A rock is thrown from the top of a ladder. The function
h(t) = -16t² + 120t + 10 gives the height of the rock t seconds after it is
thrown a certain number of feet.
1. What is the initial height that the rock was thrown from?
Answer:
h'(t)=88
Step-by-step explanation:
h'(t)=d/dt (-16t x 2 + 120t + 10)
h'(t)=d/dt (-32t + 120t + 10)
h'(t)=d/dt (88t + 10)
h'(t)=d/dt (88t) + d/dt (10)
h'(t)=88 + 0

Answer:
[tex]95ft^2[/tex]
Step-by-step explanation:
We need to multiply 10 feet by 9 feet 6 inches.
6 inches is half a foot so technically 9 feet 6 inches is 9.5 feet.
Multiply 10 by 9.5.
(10)(9.5) = 95
Therefore the answer is 95ft squared.

10th grade geometry Help!!!
Answer:
m∠W = (4x)° = 4 × 18 = 72°
m∠Y = (3x)° = 3 × 18 = 54°
m∠Z = (3x)° = 3 × 18 = 54°
Step-by-step explanation:
m∠W = (4x)°
m∠Y = (3x)°
m∠Z = (3x)°
i.e.,
We Know That,
The sum of a Triangle is 180°
So,
m∠W + m∠Y + m∠Z
i.e.,
(4x)° + (3x)° + (3x)° = 180°
10x° = 180°
x = 180/10
x = 18°
Now,
m∠W = (4x)° = 4 × 18 = 72°
m∠Y = (3x)° = 3 × 18 = 54°
m∠Z = (3x)° = 3 × 18 = 54°
Thus, x = 18°
FOR VERIFICATION ONLY:(4x)° + (3x)° + (3x)° = 180°
4 × 18 + 3 × 18 + 3 × 18 = 180
72° + 54° + 54° = 180°
180° = 180°
Hence, L.H.S = R.H.S

One fish tank is being filled while another is being drained. The first fish tank has 175 liters of water and more water is being added at a rate of 7 liters per minute. The second fish tank has 550 liters of water and is being drained at 8 liters per minute. Which equation can be used to calculate how many minutes it will it take for the two tanks to have the same amount of water?
A: 175 + 7x - 550 - 8x
B: 175 + 7x - 550 + 8x
C: 8x - 7x = 550 + 175
D: 8x - 7x = 550 - 175
Please Help!!!
In this equation, it will require 175 + 7x - 550 - 8x water to fill both tanks to the same level.
Explain about the equation?A formula that describes how two expressions on each side of a sign are connected. It typically has an equal sign and one variable. akin to this 2. 2x - 4 = 2. The variable x is present in the preceding example.
Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the expressions 3x + 5 and 14 make up the equation 3x + 5 = 14, with the word "equal" separating them.
The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.
You start first by the number of minutes that have passed.
Regardless of how many minutes have passed, the second had loses.
=175 + 7 liters
=550 liters loses 8 times
= 175 + 7x - 550 - 8x

Answer:
a₇ = [tex]\frac{4096}{3125}[/tex]
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
r = 4 ÷ 5 = [tex]\frac{4}{5}[/tex]
r = [tex]\frac{16}{5}[/tex] ÷ 4 = [tex]\frac{4}{5}[/tex]
This indicates the sequence is geometric with n th term
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 5 and r = [tex]\frac{4}{5}[/tex] , thus
a₇ = 5 × [tex](\frac{4}{5}) ^{6}[/tex] = 5 × [tex]\frac{4096}{15625}[/tex] = [tex]\frac{4096}{3125}[/tex]

if f is a linear function, f(k)=16 and f(-k)= -4 then what is the value of f(0)?
f(0) = ( f(k) +f(-k) ) / 2
f(0) = (16 - 4) / 2
f(0) = 12 / 2
f(0) = 6 → ANSWER
*Remember that f(0) = m(0) + n = n
If we have f(x) = mx + n, then:
f(k)= mk + n and f(-k)= -mk + n
If we add them:
f(k) + f(-k)
= mk + n -mk + n
= 2n
= 2f(0)
So we conclude that:
f(0) = [f(k) + f(-k)] / 2

What is the radius of a hemisphere with a volume of 324\text{ ft}^3,324 ft 3 , to the nearest tenth of a foot?
Answer:
5.4 ft
Step-by-step explanation:
Given that the volume of the hemisphere sphere, [tex]V= 324 ft^3[/tex].
Let r be the radius of the hemisphere.
As the volume of the hemisphere, [tex]V=\frac {2}{3}\pi r^3[/tex]
By using the given value, we have
[tex]\frac {2}{3}\pi r^3=324[/tex]
[tex]\Rightarrow r^3=\frac{324\times 3}{2\pi} \\\\\Rightarrow r^3=\frac{324\times 3}{2\times3.14} \\\\\Rightarrow r^3=154.78 \\\\\Rightarrow r=\left( 154.78 \right)^{1/3} \\\\[/tex]
[tex]\Rightarrow r=5.4[/tex] ft
Hence, the radius of the hemisphere is 5.4 ft.

Solve for b: 4b-11=1-2(3-b)
A) 0
B) 14
C) 3
D) -16
Answer:
4b -11 = 1 -2(3-b) (use the distributive property on -2(3-b))
4b -11 = 1 -6 +2b ( combine like terms on the right side of the = sign)
4b -11 = -5 +2b (subtract 2b from both sides)
2b -11 = -5 (add 11 to both sides)
2b = 6 (divide each side by 2)
b= 3 ( so, your answer is C)
Answer:
C
Step-by-step explanation:
4b-11=1-2(3-b)
4b-11=1-6+2b
4b-11=-5+2b
