The distance, s(t), in feet traveled by a freely falling object is given by the function s(t) = 162, where
t is time in seconds. Use this formula to find the time it would take for an object to fall to the
ground from a cliff that is 1024 feet high.
7 sec
64 sec
8 sec
9 sec
Answer:
8 seconds
Step-by-step explanation:
The correct formula is
s(t) = 16t²
-------------------------
1024 = 16t²
Divide both sides by 16
64 = t^2
Take the square root of both sides
8 = t
8 seconds

Oberon makes $13.75 an hour. He gets a 3.5% raise. What is his new hourly salary?
Answer:
$14.23
Step-by-step explanation:
Multiply the original value by 1.035 to get your answer.
Let x be the initial salary
x=13.75
Let y be the new salary
y=x+x(3.5%)
y=13.75+13.75(0.035)
y=13.75+0.48=14.23
New hourly salary=14.23$
How to solve this equation
Set up an equation for each store by multiplying the cost of the basketball by the number of basketballs bought (b) and add the cost of the hoop:
Hoops House: total = 20b + 200
Baller Basement: total = 15b + 250
Now to solve for b, set the two equations equal to each other:
20b + 200 = 15b + 250
Subtract 15b from both sides:
5b + 200 = 250
Subtract 200 from both sides:
5b = 50
Divide both sides by 5:
B = 10
The answer is 10 basketballs

Here we have
[tex]\lim_{x \to -3} f(x)=f(x)[/tex]
Therefore
[tex]\lim_{x \to -3} \sqrt{x^2 - 8} = \lim_{x \to -3} \sqrt{(-3)^2 - 8} = \lim_{x \to -3} \sqrt{9 - 8} = \lim_{x \to -3} \sqrt{1}[/tex]

Answer:
x = 73
Step-by-step explanation:
A circle is 360 degrees
4x-5 + x = 360 degrees
5x - 5 = 360 degrees
5x = 365 degrees
Divide by 5
5x/5 = 365/5

In the isosceles trapezoid ABCD, find m
Answer:
answer C
Step-by-step explanation:
Isosceles trapezoids have the property that opposite angles are supplementary.
Here are some needed properties of isosceles trapezoids.
<C and <D are supplementary
<A = <D
<B = <C
<D + <B = 180
<D = 110 Given
110 + <B = 180 Subtract 110 from both sides..
<B = 70

1. Although a Ferris Wheel is turning at a constant rate, the rate of change of height is
not constant. Explain why.
9514 1404 393
Explanation:
The "speed made good" is the product of the speed and the cosine of the angle between the direction of the speed and the direction of interest. A change in height is accomplished by speed in the vertical direction.
When a spot on the Ferris Wheel is traveling vertically, as at a side position, the angle difference is zero and the cosine is a maximum. All of the vertical speed results in a change in height.
When a spot on the Ferris Wheel is traveling horizontally, as at a top or bottom position, the angle difference from the vertical is 90°, and the cosine of the angle is 0. That is, none of the horizontal speed results in a change in height.
The vertical speed is not constant because the angle of the direction of motion with respect to the vertical is not constant.

Find the measure of angle x in the figure below:
Answer:

Step-by-step explanation:
180- 59- 52 = 69
Therefore,
69 + x + 63 = 180
x = 48
Thenks and mark me brainliest :)
Answer:
the answer is b=48
Step-by-step explanation:
52+y+59=180(angle on a straight line is 180)
collect like terms
y=180-59+52
y=180-111
y= 69
to look for x is equal to
69+x+63=180
collect like terms
x=180-69+63
x=180-132
x=48

The manager of the Danvers-Hilton Resort Hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim. a. Which form of the hypotheses should be used to test the manager's claim? H 0: less than or equal to $600 H a: greater than $600 b. When H 0 cannot be rejected, can we conclude that the manager's claim is wrong? No c. When H 0 can be rejected, can we conclude that the manager's claim is wrong? Yes
Answer:
H0 : μ ≤ 600
H1 : μ > 600
B.) NO
C.) YES
Step-by-step explanation:
Here, the null hypothesis is the claim, that mean guest bill is $600 or less ; The alternative will be the opposite of the null which is the counterclaim. This ubstge accountants assertion that guest bill has been increasing
Hence,
H0 : μ ≤ 600
H1 : μ > 600
When the null cannot be rejected, that means there is no sufficient evidence to support the alternative hypothesis, Hence, we stick with the manager's claim
When H0 can be rejected, then there is sufficient evidence to support, the accountant's claim. Thus, we go with the accountant's claim and conclude that the manager is wrong.

Step-by-step explanation:
please I'm not sure for the numbers 3 and 2.
for number 10,
2/3x -4 = 3 +5
2/3x = 8+4
2/3x = 12
2x= 12 x 3
2x = 36
x = 18
and for number 4
(y+1)/5 - (y-2)/4 = -1
to clear out the fraction, multiply throughout by 20
after multiplying, we have
4(y+1) -5(y-2)= -20
4y+4-5y+10 =-20
14 -y = -20
-y = -20 + 14
-y = -6

A report states that the mean household income last year for a certain rural county was $46,200 and the median was $37,800. If a histogram were constructed for the incomes of all households in the county, would you expect it to be skewed to the right, to the left, or approximately symmetric
Answer:
skewed to the right
Step-by-step explanation:
Given that
the mean household income for the last year was $46,200
And, the median was $37,800
In the case when the historgram is prepared so the income would be skewed to the right as the mean i..e $46,200 is more tha the median i.e. $37,800
So, the distribution would be right skewed
Hence, the same would be considered and relevant

Step-by-step explanation:
Given that,
The length of the rectangle, [tex]L=\dfrac{2}{13}\ yards[/tex]

Find the equation of a circle whose endpoints of the diameter are (15, - 3) and (7,3). The equation of the circle is (Simplify your answer. Type your answer in standard form.)
Answer:
(x - 11)² + y² = 25
Step-by-step explanation:
First find the center
O = ( (15 +7 / 2), (-3 + 3)/2 )
O = (11, 0)
Then find the radius squared
use the distance formula from the center to either end point of the diameter
r² = (15 - 11)² + (-3 - 0)²
r² = 16 + 9
r² = 25
Formula for circle
(x - h)² + (y - k)² = r²
(h, k) is the center = (11, 0)
The equation is
(x - 11)² + y² = 25
