Answer:
2.56
Step-by-step explanation:
The equation they dive u: d = 16t^2, so in the question they said what's the distance, d, if t = 0.4
So you just have to replace t with 0.4:
d = 16t^2
d = 16(0.4)^2
d = 16(0.16)
d = 2.56

A. (2, 0) B. (-2, 0) C. (0, 2) D. (0, -2
Answer:
The answer is B. (-2, 0)
Step-by-step explanation:
x= 2 ⋅ cos(π) = −2
y=2 ⋅ sin(π) = 0
The rectangular coordinates is (-2 , 0) , Option B is the correct answer.
What is the equation of conversion of Polar Coordinates to Rectangular Coordinates ?The equation for a polar point ( r, [tex]\rm \theta[/tex]) is
x = rcos [tex]\rm \theta[/tex]
y =r sin [tex]\rm \theta[/tex]
where (x , y) are rectangular coordinates.
The polar coordinate given is ( 2 , π)
r = 2
[tex]\rm \theta[/tex] = π
so
x = 2 cos π
x = 2 * (-1)
x = -2
y = 2 sin π
y = 2 *0
y = 0
Therefore the rectangular coordinates is (-2 , 0) , Option B is the correct answer.

A rectangle has a length of x and a width of 3x3 + 9 − x2. Find the perimeter of the rectangle when the length is 6 feet. Please HELP :(
Answer:
24
Step-by-step explanation:
A rectangle as four sides, and as we know, two of the sides equal each other. I would first start by drawing a rectangle. On one length on the outside of the triangle, put x. On the opposite congruent length, put x again since we know the sides are the same. You should have two blank sides left. On both of those sides, put 3x3 + 9 - x2 (I am assuming that you meant x squared whenever you said x2. Let me know if I assumed incorrectly. Because the length is 6, we know that x must be six. Now substitute everything that says x with the number six. Use parenthesis so you don't confuse it with other numbers. (6.) Now add everything up. You should be adding 3x3 + 9 - (6)2+ 3x3 + 9 - (3)2 + 6 + 6. Your final answer should be 24.
Then again, because this question could of meant 2x rather than x^2, this could be completely wrong, so if you take a picture of the exact question I will be able to help you better. Also, I'm not sure if your 3x3 is an x or an multiplication sign.
The original selling price of a shirt was $45.
In a sale, the shirt is reduced to $32.50.
Calculate the percentage reduction,
Show your working
Given:
The original selling price of a shirt was $45.
In a sale, the shirt is reduced to $32.50.
To find:
The percentage reduction.
Solution:
We know that,
[tex]\text{Percentage reduction}=\dfrac{\text{Original value - Reduced value}}{\text{Original value}}\times 100[/tex]
[tex]\text{Percentage reduction}=\dfrac{45-32.50}{45}\times 100[/tex]
[tex]\text{Percentage reduction}=\dfrac{12.50}{45}\times 100[/tex]
On further simplification, we get
[tex]\text{Percentage reduction}=\dfrac{1250}{45}[/tex]
[tex]\text{Percentage reduction}=27.777778[/tex]
[tex]\text{Percentage reduction}\approx 27.78[/tex]
Therefore, the percentage reduction is 27.78%.

Ariel wants to find out the most popular theme for spirit week at school. She cannot decide between two methods. Option 1: She will poll each student who leaves the gym after sports practice. Option 2: She will randomly poll three students from each first-period class. Which statement about the methods is true? Option 1 is biased. Option 2 is biased. Neither is biased. Both are biased.
Answer:
Option 1 <3
Step-by-step explanation:
Option 1: Not everyone might be in a sports class and not everyone might be leaving at the exact same time.
Option 2: This way of collecting information is not biased because it is random and includes a wide variation of people.
Using sampling concepts, it is found that the correct option is given by:
Option 1 is biased.
What is sampling?Sampling is when a group is taken from a population to estimate a parameter or a characteristic. It has to take into account the entire population to avoid bias, which generate false results.
In this question, all students have to be considering, not just the ones who like sports practice, hence Option 1 is biased.

What’s the distance 3 1/4 and -15
Answer:
18 1/4
Step-by-step explanation:
The easiest way to do this is to start at 0 and go 3 1/4 units to your right.
Then start at 0 and go -15 units to your left. So far I have not used a formula because I want you to see intuitively what the answer is. Then we'll do it with a formula.
The total distance is 3 1/4 + 15 = 18 1/4. Purists will hate the way I've done it, but beginners should understand what they are doing.
A formula would look like this
distanace = sqrt( x2 - x1 )^2 + (y2 - y1)^2 )
distance = sqrt( (3 1/4 - - 15)^2 + (4 - 4)^2 )
distance = sqrt( (18 1/4 )^2 + 0)
distance = 18 1/4
What is the slope and y-intercept of the equation 3x -y=3
Answer:
Slope = 3
Y Intercept = 3
Step-by-step explanation:
3x - y = 3
(subtract 3x from both sides - we have to get y by itself)
-y = -3x - 3
(divide by -1 from both side - we need to make y positive)
y = 3x + 3
