Answer:
Step-by-step explanation:
it would be "c" because the question asks for the number that makes the inequality true
4x≤ x+3
the graph in c is saying that every number that is 1 or less than 1 makes the inequality true. so lets take -7 as an example
4 x -7=-28
-28+3=-25
-25 is greater than -28 so the inequality is true. the reason why graph d doesnt work is because if we plug in 2 into the equation, then 4x =8 and x+3=5
5 is not greater than 8 so it doesnt work

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 220 grams of a radioactive isotope, how much will be left after 5 half-lives?
Answers
Answer:
\(\boxed{6.875 \text{\: grams}}\)
Step-by-step explanation:
Half-lives are how long it takes for half of a substance to decay. If you start with a certain amount and it decays for a certain amount of half-lives, you are dividing by \(2^{x}\), where x is equal to the amount of half-lives.
In order to solve this question, simply divide the starting value by 2 raised to the value of half-lives.

A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 1700 seats
Answers
The percentage of the seats that is filled is 39%.
What is percentage?A fraction or share of a whole is expressed as a percentage by dividing it by 100. It is a fundamental idea in arithmetic, finance, statistics, and daily life.
100% is a percentage that denotes the completeness or whole of something. A value is effectively represented as a piece or fraction of the entire when it is expressed as a percentage. "%" is the symbol for percentage.
We can see that the number of the filled seats would be;
1700 - 1037
= 663 seats
Percentage of the filled seats = 663/1700 * 100/1

When the scale factor is 1, what is the ratio of the side length of the side opposite ∠A and the length of the hypotenuse?
Answers
when the scale factor is 1, we have:
(side length of side opposite ∠A) / (length of hypotenuse) = sin A
When the scale factor is 1, the ratio of the side length of the side opposite ∠A to the length of the hypotenuse remains the same as in the original triangle. In a right triangle, the side opposite ∠A is referred to as the "opposite" side, and the hypotenuse is the longest side.
The ratio of the side length of the side opposite ∠A to the length of the hypotenuse is commonly known as the sine of angle A (sin A). So, when the scale factor is 1, the ratio of the side length of the side opposite ∠A to the length of the hypotenuse is equal to sin A.
In mathematical terms, when the scale factor is 1, we have:
(side length of side opposite ∠A) / (length of hypotenuse) = sin A
It's important to note that this ratio holds true for any right triangle, regardless of its size or dimensions, as long as the angle A remains the same.

Let u=〈1,9,−8〉, v=〈1,8,−4〉, and w=〈4,−9,−9〉. Compute the following scalar triple product.
u⋅(v×w)=
Answers
The value of The First Vector: 〈-16/√(721), -16/√(721), -13/√(721)〉
Second Vector: 〈0, -1/√(5), -2/√(5)〉
u⋅(v×w) is 312
In mathematics, vectors are an essential concept that is widely used in many different fields. They are used to represent physical quantities such as velocity, force, and acceleration, and also have important applications in computer graphics, engineering, and physics. In this explanation, we will discuss the concept of unit vectors and scalar triple products.
The first unit vector can be found as follows:
a x b = 〈-5, 4, -5〉 x 〈-3, -4, 1〉 = 〈-16, -16, -13〉
To normalize this vector, we divide each component by its magnitude:
||〈-16, -16, -13〉|| = √((-16)² + (-16)² + (-13)²) = √(721)
So, the first unit vector is:
v₁ = 〈-16/√(721), -16/√(721), -13/√(721)〉
To find a second unit vector that is also orthogonal to a and b, we can take the cross product of a and v1:
a x v₁ = 〈-5, 4, -5〉 x 〈-16/√(721), -16/√(721), -13/√(721)〉 = 〈0, -1/√(721), -4/√(721)〉
To normalize this vector, we divide each component by its magnitude:
||〈0, -1/√(721), -4/√(721)〉|| = √((1/√(721))² + (4/√(721))²) = 1/√(5)
So, the second unit vector is:
v₂ = 〈0, -1/√(5), -2/√(5)〉
Now, let's move on to the scalar triple product. The scalar triple product of three vectors u, v, and w is defined as the dot product of u with the cross product of v and w:
u ⋅ (v x w)
To compute this, we first need to find the cross product of v and w:
v x w = 〈8, -5, -40〉
Then, we can take the dot product of u with the resulting vector:
u ⋅ (v x w) = 〈1, 9, -8〉 ⋅ 〈8, -5, -40〉 = 1(8) + 9(-5) + (-8)(-40) = 312

For the following vectors, (a) find the dot product v•w ; (b) find the angle between v and w , (c) state whether the vectors are parallel, octagonal, or neither. V=-3i-4j, w=6i+8j
A- v•w
B-the angle between v and w is theta ^•?
C- the vectors v and w are?
Answers
B) The angle between vectors v and w can be found using the formula: cos(theta) = (v • w) / (||v|| ||w||), where ||v|| and ||w|| are the magnitudes of vectors v and w respectively.
First, we need to find ||v|| and ||w||:
||v|| = sqrt((-3)^2 + (-4)^2) = 5
||w|| = sqrt((6)^2 + (8)^2) = 10
Now, we can substitute in the values to get:
cos(theta) = (-50) / (5 * 10) = -1
theta = arccos(-1) = pi radians or 180 degrees.
Therefore, the angle between vectors v and w is 180 degrees.
C) Two vectors are parallel if their directions are the same, which can be determined by comparing their unit vectors.
The unit vector of v is:
v_hat = v / ||v|| = (-3/5)i + (-4/5)j
The unit vector of w is:
w_hat = w / ||w|| = (6/10)i + (8/10)j = (3/5)i + (4/5)j
We can see that the unit vectors are in opposite directions, which means that the vectors are anti-parallel or opposite. Therefore, the vectors v and w are neither parallel nor orthogonal.

1. Global warming creates local problems. Projections forecast that even a moderate air temperature increase of only 1.8 °F could cause brook trout distributions to decrease dramatically. For example, such a temperature increase would take Washburn county's 19 ponds that support brook trout down to 10 ponds. What would be the percent decrease in the number of ponds that support brook trout?
Answers
The percent decrease in the number of ponds that support brook trout would be approximately 47.37%.
To calculate the percent decrease in the number of ponds that support brook trout, we need to determine the difference between the initial number of ponds and the final number of ponds, and then express that difference as a percentage of the initial number of ponds.
Initial number of ponds: 19
Final number of ponds: 10
To calculate the percent decrease, we can use the following formula:
Percent Decrease = (Difference / Initial Value) * 100
Let's apply this formula to the given data:
Difference = Initial number of ponds - Final number of ponds
Difference = 19 - 10
Difference = 9
Percent Decrease = (9 / 19) * 100
Now, let's calculate the percent decrease:
Percent Decrease = (9 / 19) * 100
Percent Decrease ≈ 47.37%

A bag contains 3 blue marbles, 10 green marbles, 4 yellow marbles, and 8 red marbles. A marble is chosen at random, not replaced, then another marble is chosen. What is the probability that it is a red marble, then a blue marble? Write your answer as a fraction in simplest form.
Answers
Answer:
There are a total of 25 marbles in the bag.
The probability of choosing a red marble first is 8/25 since there are 8 red marbles out of 25 marbles in the bag.
Since a marble is not replaced after the first selection, there are now 24 marbles in the bag. There are still 3 blue marbles in the bag.
The probability of choosing a blue marble second, after a red marble has already been selected, is 3/24 or 1/8 since there are 3 blue marbles left out of 24 marbles in the bag.
To find the probability of both events occurring together, we multiply their individual probabilities:
8/25 x 1/8 = 1/25
Therefore, the probability that a red marble is chosen first, followed by a blue marble, is 1/25.
