A ball is kicked from a height of 3 feet above ground the height of the ball is h(t) is given by h(t) = 5t raised to the 2 power +14t+3 where t is the time in seconds after the ball is kicked. How long will it take the ball to hit the ground after kicked?
Answers
Answer:
t = -2.566s and -1.169s
Step-by-step explanation:
Given the height of the ball expressed at
h(t) = 5t²+14t+3
The ball will hit the ground at h(t) = 0
Substitute and get t
0 = 5t²+14t+3
Use general formula
t = -14+/- √14²-4(5)(3)/2(5)
t = -14+/- √196-60)/10
t = -14+/- √136/10
t =-14+/- 11.66/10
t = -25.66/10 and -2.338/2
t = -2.566s and -1.169s
Hence the ball will hit the ground at these times
Emilia went out to eat dinner, and the meal cost $20.00. If Emilia received a 30% discount, what was the total

The distribution of household incomes in a small town is strongly skewed to the right. The mean income is $42,000 and the standard deviation is $24,000. The Ames family’s household income is $60,000. The z-score for the Ames family’s income is
Answers
Answer:
0.75
Step-by-step explanation:
Given :
mean = 42000
Standard deviation = 24000
score, x = 60000
The Zscore :
Zscore = (score - mean) / standard deviation
(60000 - 42000) / 24000
18000 / 24000
= 0.75

If 4x - 8 = 4 , find the value of x
Answers
Answer:
x=3
Step-by-step explanation:
4x-8=4
4x=12
4x/4=12/4
x=3
Answer:
x = 3
Step-by-step explanation:
Add 8 to both sides.
4x = 4 + 8
Simplify 4 + 8 to 12.
4x = 12
Divide both sides by 4.
x = 12 ÷ 4
Simplify 12 ÷ 4 to 3
x = 3

[tex]x\geq 2[/tex]
Step-by-step explanation:
The parent function, [tex]y=\sqrt{x}[/tex], has a domain of [tex]x\geq 0[/tex] or [tex][0, \infty)[/tex], because the value under the radical cannot be less than 0 (we cannot take the square root of a negative number). Thus, by setting everything inside the radical to 0, we can find the domain of this function:
[tex]x-2\geq 0,\\x\geq 2[/tex]
Thus this domain of this function is:
As an inequality: [tex]x\geq 2[/tex] (desired in problem)
In interval notation: [tex][2, \infty)[/tex]

Initially, the ratio of Alex's toy cars to Pete's toy cars was 7:3. After Alex gave 20 toy cars to Pete, they each had an equal number of cars. how many toy cars did they have altogether?
Answers
Answer:
100 cars
Step-by-step explanation:
Alex: Pete
7: 3
Multiply by x to get the number of cars
Alex has 7x cars
Pete has 3x cars
Now Alex gives pete 20
Alex has 7x-20
Pete has 3x+20
They have the same number of cars so set the expressions equal
7x-20 = 3x+20
Subtract 3x from each side
7x-20-3x = 3x+20-3x
4x-20 = 20
Add 20 to each side
4x-20+20 = 20+20
4x= 40
Divide by 4
4x/4 = 40/4
x = 10
Alex had 7x = 7*10 = 70 to start
Pete had 3x = 3*10 = 30 to start
Together 70+30 = 100 cars
Answer:
100 cars
Step-by-step explanation:
Alex: Pete
7: 3
Multiply by x to get the number of cars
Alex has 7x cars
Pete has 3x cars
Now Alex gives pete 20
Alex has 7x-20
Pete has 3x+20
They have the same number of cars so set the expressions equal
7x-20 = 3x+20
Subtract 3x from each side
7x-20-3x = 3x+20-3x
4x-20 = 20
Add 20 to each side
4x-20+20 = 20+20
4x= 40
Divide by 4
4x/4 = 40/4
x = 10
Alex had 7x = 7*10 = 70 to start
Pete had 3x = 3*10 = 30 to start
Together 70+30 = 100 cars

Jack can program an app in 3 hours. Chris can program the same app in 8 hours. How long would it take them to program the same app working together?
Answers
Answer:
2 2/11 hours
Step-by-step explanation:
Let the number of hours
Jack spent programming his app = J
Chris spent programming his app = C
Total hours if they worked together = T
Hence,
1/T = 1/3 + 1/8
Lowest Common Denominator = 34
1/T = 8 + 3/24
1/T = 11/24
Cross Multiply
T × 11 = 1 × 24
T = 24/11
T = 2 2/11 hours
Therefore, it would take them to program 2 2/11 hours to program the same app working together
Find the GCF of the expression 24a^7 +18a^5+12a^3
Answers
Answer:
the correct answer is 6a³
Answer:
6a³
Step-by-step explanation:
First find the GCF of the numbers, which is the easy part...
The largest number that 24, 18, and 12 can all be divided by is 6.
So 6 is the first part of the GCF.
Now for the variable...
The smallest exponent in an instance of the variable is 3.
So a³ is the variable part.
GCF: 6a³

If f(y) = e^(9y) + e^(-9y), find f'(y). Use exact values.
Answers
Given:
[tex]f(y)=e^{9y}+e^{-9y}[/tex]
To find:
The f'(y).
Solution:
Chain rule of differentiation:
[tex][f(g(x))]'=f'(g(x))g'(x)[/tex]
Differentiation of exponential:
[tex]\dfrac{d}{dx}e^x=e^x[/tex]
We have,
[tex]f(y)=e^{9y}+e^{-9y}[/tex]
Differentiate with respect to y.
[tex]f'(y)=e^{9y}\dfrac{d}{dx}(9y)+e^{-9y}\dfrac{d}{dx}(-9y)[/tex]
[tex]f'(y)=e^{9y}\cdot 9(1)+e^{-9y}\cdot (-9)(1)[/tex]
[tex]f'(y)=9e^{9y}-9e^{-9y}[/tex]
Therefore, the differentiation of the given function is [tex]f'(y)=9e^{9y}-9e^{-9y}[/tex].
