Given three interior angle measures of a triangle:

Use the triangle sum theorem to find the missing angle:

So the missing angle is 67°.

The equation of the line tangent to the curve at the point corresponding to the given value of t.

x = t²-23 and y = t³ + t, at t = 5 is

38x - 5y + 574 = 0

Given, a curve with the points represented by

x = t²-23 and y = t³ + t, at t = 5

we have to find an equation of the line tangent to the curve at the given point on the curve.

so, the given point is (x , y) = (5² - 23 , 5³ + 5)

(x , y) = (2 , 130)

Now, the slope of the curve at that point be,

dy/dx = (3t² + 1)/(2t)

dy/dx = 76/10

Now, on using the slope-intercept form, we get

(y - 130)/(x - 2) = 38/5

5(y - 130) = 38(x - 2)

5y - 650 = 38x - 76

38x - 5y + 574 = 0

Hence, the equation of the line tangent to the curve at the point corresponding to the given value of t.

x = t²-23 and y = t³ + t, at t = 5 is

38x - 5y + 574 = 0

We need to identify a matrix X such that X1AX is in diagonal form in order to write A=[1 1 0 3] as XX1. One option is:

X = [1 1 1 0; 1 1 -1 0; 0 0 0 1; 1 -1 0 0]

Then, X⁻¹ = (1/4)[-1 1 -1 3; 1 1 1 -1; 0 0 0 4; -1 1 1 1]

X⁻¹AX = [5 0 0 0; 0 -1 0 0; 0 0 0 0; 0 0 0 -2]

A = X[5 0 0 0; 0 -1 0 0; 0 0 0; 0 0 0 -2] so.X⁻¹.

We must exponentiate each block of the diagonal matrix in order to determine eAt, so:

X[e5t 0 0 0; 0 e-t 0 0; 0 0 1 0; 0] = eAt

eA0 = X[e0 0 0 0; 0 e0 0 0; 0 0 1 0; 0 0 0 e0]X⁻¹

= X[I]X⁻¹

= AA⁻¹

= I

To find the derivative of eAt at t=0, we can use the formula:

d/dt(eAt)|t=0 = AXe0X⁻¹

= AXIX⁻¹

= A

Therefore, we have eA0 = I and d/dt(eAt)|t=0 = A.

Based on the given information and the secant-Secant Theorem, we have derived the equation (XY * XZ) = (10X * 10X).

Given that Circle U has points X and Z on the circle, and secant segments XY and ZY intersect at point Y outside the circle, we will use the following terms in our answer: Circle, Secant Segments, Intersection, and Ratio.

Step 1: Identify the segments involved.
We have two secant segments intersecting at point Y: XY and ZY.

Step 2: Apply the secant-secant theorem.
According to the secant-secant theorem, the product of the lengths of the segments from the intersection point to the points on the circle should be equal. In other words, (XY * XZ) = (ZY * ZY).

Step 3: Apply the given ratio.
We are given that ZY = 10X. Let's substitute this into the equation from Step 2: (XY * XZ) = (10X * 10X).

Step 4: Solve for XY and XZ.
Now, we need to solve for XY and XZ using the equation from Step 3. However, since we only have one equation and two variables, we cannot solve it completely. We need more information to find the specific values of XY and XZ.

Based on the given information and the secant-secant theorem, we have derived the equation (XY * XZ) = (10X * 10X). To find the specific values of XY and XZ, additional information is required.

The slope of the line which is perpendicular to the given line 3x+18y=108 is (6).

We already know the equation of a line in slope intercept form y = mx + b and we also know that perpendicular lines that have slopes which are negative reciprocals of each other.

Given a line 13x + 18y=108, this slope intercept form can be written as,

3x + 18y = 108

18y = 108 - 3x

y = (108 /18) - (3/18)x.

y = (6) - 1x/6.

y = -(1/6)x + 6.

Hence the slope of the given line is (-1/6), thus the slope of the line which is perpendicular is (6).

There is no real number solution to this equation. Therefore, it is not possible to find an equation relating a, b, and c that guarantees the given linear system to be consistent for any values of a, b, and c.

To ensure that the given linear system is consistent for any values of a, b, and c, we need to find an equation that guarantees the existence of a solution.

This can be achieved by setting up a condition on the coefficients of the system such that the determinant of the coefficient matrix is zero.

Let's consider the coefficient matrix A:

A = [[1, 2, -3],

[2, 3, 3],

[5, 9, -6]]

We want to find an equation relating a, b, and c such that the determinant of A is zero.

det(A) = 0

Using the properties of determinants, we can expand the determinant along the first row:

det(A) = 1 * det([[3, 3], [9, -6]]) - 2 * det([[2, 3], [5, -6]]) + (-3) * det([[2, 3], [5, 9]])

Simplifying further, we have:

det(A) = 1 * (3*(-6) - 39) - 2 * (2(-6) - 35) + (-3) * (29 - 3*5)

det(A) = -54 + 2*(-12) - 3*3

det(A) = -54 - 24 - 9

det(A) = -87

Setting the determinant equal to zero, we get:

-87 = 0

However, there is no real number solution to this equation. Therefore, it is not possible to find an equation relating a, b, and c that guarantees the given linear system to be consistent for any values of a, b, and c.

If you want to travel the recipe to make a smaller batch of 12 cookies, you would need 1/3 cup of flour, for preparing the chocolate chip cookies.

If a recipe for chocolate chip cookies calls for 2/3 cup of flour, then if you want to triple the recipe, you would need 2/3 x 3 = 2 cups of flour.

However, if you want to travel the recipe, meaning reduce the recipe to make a smaller batch, then you need to know the ratio of the ingredients.

For example, if the original recipe made 24 cookies, and you only want to make 12 cookies, then you would need to reduce all of the ingredients by half.

Since the recipe calls for 2/3 cup of flour to make 24 cookies, to make 12 cookies, you would need:

Step-by-step explanation:

Let the first number be \(x\)

The next number be \(2\) more than the previous as it is an even number

The second number is \(x+2\)

and the last number is \(x+4\)

The sum of the numbers is \(108\), so the expression will be

\(x+(x+2)+(x+4)=108\)

\(\Rightarrow 3x+6=108\)

\(\Rightarrow x=\dfrac{108-6}{3}\)

Answer:

The time it'd take for the element to have 15 g of mass is approximately 68 min.

Step-by-step explanation:

The radioactive decay of a substance is given by the following formula:

Since the element has a half life of 12 minutes, this means that after this time the mass of the element will be half of it was originally, therefore:

Therefore the mass of the element is given by:

If the initial mass is 760 g and the final mass is 15 g, we have:

The time it'd take for the element to have 15 g of mass is approximately 68 min.

Step-by-step explanation:

Element X take 32.6 minutes to decay to 87 grams.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Element X decays radioactively with a half life of 15 minutes.

And, there are 400 grams of Element X.

Now, By the given information, we can formulate;

⇒ \(y = x (0.5)^{t/h}\)

Substitute all the values we get;

⇒ 400 = 87 × \((0.5)^{t/15}\)

⇒ 400 / 87 =  \((0.5)^{t/15}\)

⇒ 4.6 =  \((0.5)^{t/15}\)

Take log both side,

⇒ ln 4.6 = t/15 (ln 0.5)

⇒ 1.52 = t/15 x 0.7

⇒ t = 32.6 minutes

Thus, Element X take 32.6 minutes to decay to 87 grams.

Therefore, probability solution is estimating this likelihood without additional data or analysis is inappropriate correct response is option a.

The main goal of the mathematical branch known as statistical inference is to estimate the likelihood that a statement is accurate or that a particular event will take place. Any number among 0 and 1, where 1 typically denotes confidence and 0 typically denotes possibility, can be used to symbolise chance. A probability diagram illustrates the likelihood that a particular occurrence will take place.

Here,

Because of the skewed demographic distribution, the right response is (a).

We could use the normally distributed to compute probabilities because the length of adult American ladybirds is distributed normally with a known standard deviation. The normal distribution may not, however, correctly depict the distribution of ladybird lengths in the population due to the skewed population distribution.

Furthermore, even if the difference between the actual community mean and the assumed mean of 1 cm is tiny, the given size of the population of 440000 could result in a statistically significant outcome.

However, because the assumption of normality may not hold true, this does not imply that we can accurately determine the likelihood of a random ladybird in Raleigh being larger than 1.5 centimetres.

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

For example , in an equation 6x +5x = 3x + 24 , to find x in this equation we need to follow some steps;

First we collect like terms

6x +5x - 3x = 24

8x = 24

then we divide both sides by the coefficient of x

x = 24/8

x = 3

Similarly , solving 18 - 2x = 4x

collect like terms

18 = 4x +2x

18 = 6x

divide both sides by coefficient of x

x = 18/6 = 3
