Answer:5
Step-by-step explanation:
A car accelerates uniformly from 3.5 m/s to 12.5 m/s in 4.5 s.
What is the magnitude of the acceleration?
a) 0.3 m/s²
b) 0.5 m/s²
c) 2.0 m/s²
d) 3.6 m/s²
Answer:
c) 2.0 m/s^2.
Step-by-step explanation:
Acceleration = change of velocity / time
= (12.5 - 3.5)/4.5
= 9/4.5
= 2.0 m/s^2.
When you plug in 8 for m, what problem will you have to solve?
3+m
3+m=8
3+8
fraction equivalent to 3/8 with denominator of 72

SOLVE THR SIMULTANEOUS EQUATIONS
3X+Y=8
X-3Y=11
ANSWER PLEASE
Answer:
if you just wanted the equations fixed: y= -3x + 8 & y= 1/3x - 11/3
but if you wanted x then x = 7/2
Step-by-step explanation:
3x + y = 8 *subtract 3x from both sides*
y = -3x + 8
x - 3y = 11 *add 3y to both sides*
x = 3y + 11 subtract 11 from both sides*
x - 11 = 3y * divide both sides by 3*
1/3x - 11/3 = y --> y = 1/3x - 11/3
and to solve for x i just used ma thway but if you did want to solve it you'd need to put the equations equal to each other --> -3x + 8 = 1/3x - 11/3
Can someone help me please?

the population of a deer in the national park in model by the equation P = 300e^(it). If the population of the deer is 400 after 2 years, find the value of k. Round your answer to the nearest hundredth. NO LINKS!!!
Answer:
k ≈ 0.14
Step-by-step explanation:
Given
P = 300 [tex]e^{kt}[/tex]
Substitute P = 400 and t = 2 into the equation
400 = 300 [tex]e^{2k}[/tex] ( divide both sides by 400 )
[tex]e^{2k}[/tex] = [tex]\frac{4}{3}[/tex] ( take ln of both sides )
ln [tex]e^{2k}[/tex] = ln ([tex]\frac{4}{3}[/tex] )
2k = ln ([tex]\frac{4}{3}[/tex] ) ( divide both sides by 2 )
k = [tex]\frac{ln\frac{4}{3} }{2}[/tex] ≈ 0.14 ( to the nearest hundredth )
Hoang has worked as a nurse at Springfield General Hospital for 7 years longer than her friend Bill. Two years ago, she had been
at the hospital for twice as long. How long has each been at the hospital?
Answer:
[tex]Bill\to 9\ years[/tex]
[tex]H \to 16\ years[/tex]
Step-by-step explanation:
Let
[tex]H \to Hoang[/tex]
[tex]B \to Bill[/tex]
Currently:
[tex]H = B + 7[/tex]
Two years ago
[tex]H - 2 = 2 * (B -2)[/tex]
Required
H and B
We have:
[tex]H - 2 = 2 * (B -2)[/tex]
Open bracket
[tex]H -2 =2B - 4[/tex]
Add 2 to both sides
[tex]H -2+2 =2B - 4+2[/tex]
[tex]H =2B -2[/tex]
Substitute [tex]H = B + 7[/tex]
[tex]B + 7 =2B -2[/tex]
Collect like terms
[tex]2B - B =7+2[/tex]
[tex]B = 9[/tex]
Substitute [tex]B = 9[/tex] in [tex]H = B + 7[/tex]
[tex]H = B + 7[/tex]
[tex]H = 9 + 7[/tex]
[tex]H = 16[/tex]

The residuals are normally distributed. b. The model over predicts the value of the dependent variable for small values and large values of the independent variable. c. The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship. d. The residuals have a constant variance.
Answer: Hello the scatter plot related to your question is missing attached below is the scatter plot
answer : The model fails to capture the relationship between the variables accurately, and there may exist nonlinear relationship ( C )
Step-by-step explanation:

Find the area of the triangle
Answer:
About 292.72
Step-by-step explanation:
We can imagine a circle circumscribed around the triangle, then solve it as we normally do using the apothem. By dividing 360 by the number of sides (3) we know that the central angle constructed by the apothem and radiuses would be 120. Divided by 2 (because we are using a right triangle to solve it) is 60. Now with this you can either use trig ratios (sin, cos, or tan) or use special right triangles (30-60-90 or 45-45-90). I used special rights. With this I know my apothem is [tex]\frac{13\sqrt{3} }{3}[/tex]. Perimeter is 26 times 3 which is 78. The formula for area of regular polygons is 1/2(perimeter times apothem). When we plug our values in the answer is about 292.72. You are lucky that I just had my test on this, I hope it helps.
Here is my work since this is very visual for me:
Is a triangle with side lengths of 33 inches, 56 inches, and65 inches a right triangle? Explain your reasoning.
Answer:
Yes
Step-by-step explanation:
Pythagorean's Theorum is that a^2 + b^2 = c^2
a and b are the sides of the triangle and c is the hypotenuse. 33x33+56x56=4225 sqrt4225 is 65. Everything checks out.

the results of rolling a single die are shown in a table below. find the experimental probability of rolling a 5
number total
1 12
2 16
3 21
4 23
5 18
6 10
Answer:
1/12
Step-by-step explanation:
To find experimental probability you have to solve the Number of times an event occurs / Total number of trials. So since the 5 only appears once and there are 12 numbers, it would be 1/12. Did this help?
The experimental probability of rolling 5 will be 0.18.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
The table is given below:
Number Total
1 12
2 16
3 21
4 23
5 18
6 10
The experimental probability of rolling a 5 is calculated as,
P = 18 / (12 + 16 + 21 + 23 + 18 + 10)
P = 18 / 100
P = 0.18
Thus, the probability is 0.18.
More about the probability link is given below.

Answer:
(d) {-7, -2, 11, 20}
Step-by-step explanation:
You can put the domain values into the function and evaluate to find the corresponding range values. Here, we'll do them "all at once."
y = 3{-4, -1, 2, 5} +5
= {-12, -3, 6, 15} +5
= {-7, 2, 11, 20} . . . . . matches choice d
_____
To save yourself some arithmetic, you can observe that the answer choices differ in the 2nd and 4th values, so you only need to evaluate the function for x=-1 or x=5 to determine the correct answer choice.
