Answer:
B. 75.36 cubic cm
Step-by-step explanation:
We will use the formula V=π times r² times h
so, V= 3.14 times 2² times 6
so, V= 3.14 times 4 times 6
= 3.14 times 24
=75.36 cubic cm

Uma volta inteira na Terra corresponde a uma distância 2πr≅40.000 km. Se um satélite leva 85 minutos para dar uma volta completa ao redor da Terra, qual a sua velocidade média em m/s (metros por segundo)
Answer:
7.8. 10 ^ 3 m / s
Step-by-step explanation:
The computation of the average speed in m/s is shown below:
The average speed equation is
= ΔS ÷ Δt;
As We know that
an entire revolution would be40,000 km
and a satellite takes 85 minutes to complete a revolution,
So,
ΔS = 40,000 km = 40,000,000 m
Δt = 85 min = 5 100 s
Now the average speed is
= 40 000 000 ÷ 5 ÷ 5 100
= 7843.14 m / s
= 7.8. 10 ^ 3 m / s

Answer:
A = (5x - 1) (x^2 + 4)
Step-by-step explanation:
Area = length × width
= (5x - 1) (x^2 + 4)
Trevor pet goat weighed 6 3/ pounds when oit was born. By age 3 the goat weighted 8 times as much. Fill in each box with a number or sysmobe to answer tthis question.
Answer: 51 pounds
Step-by-step explanation:
Since the goat weighed 6 3/8 pounds and weighed 8 times as much by age 3, the weight of the goat at age 3 will be gotten by multiplying 6 3/8 by 8. This will be:
= 6 3/8 × 8
We change 6 3/8 to an improper Fraction
= 51/8 × 8
= 51 pounds
The weight is 51 pounds

Answer:
22
Step-by-step explanation:
You can also use the radius of the circle and the arc length to find the central angle. Call the measure of the central angle θ. Then: θ = s ÷ r, where s is the arc length and r is the radius.
So...
0=31 divided by 22
0
22 remainder
0=22
22 is the arc's central angle.

Answer: Pretty sure its A.
Step-by-step explanation:
A community theater uses the function p(d)= -5d²+300d -200 to model the profit (in dollars) expected in a weekend when the tickets to a comedy show are priced at d dollars each: Part A: Write and solve an equation to find out the prices at which the theater would earn $2,300 in profit from the comedy show each weekend. Show your reasoning Part B: At what price would the theater make the maximum profit. and what is that maximum profit? Show your reasoning.
Answer:
A. $66.33B. $4300Step-by-step explanation:
Given function:
p(d)= -5d² + 300d - 200 Part Ap(d) = 2300, find d:
2300 = -5d² + 300d - 200 5d² - 300d + 200 - 2300 = 05d² - 300d - 2100 = 0d² - 60d - 420 = 0d²- 2*30d + 900 = 1320(d - 30)² = 1320d- 30 = √1320d = 30 + 36.33d = 66.33 Part BMaximum point of the function is obtained at vertex, which is (x = -b/2a):
d = - 300/-10 = 30The maximum profit is:

Write an equation to represent the exponential A wildlife biologist determines that there are approximately 200 deer in a region of a national park. The population grows at a rate of 7% per year. Write an equation to represent the exponential growth of the population.
Answer:
FV= 200*(1.07^n)
Step-by-step explanation:
Current population= 200 deer
Growth rate= 7% per year
To calculate the future value of deer in any given years, we need to use the following formula:
FV= PV*(1+g)^n
FV= future value
PV= present value
g= growth rate
n= number of years
FV= 200*(1.07^n)
For example, the population in 5 years:
FV= 200*(1.07^5)
FV= 281
A traingle has coordinates at A(-2,0) B(-4,4) and C(1, 6). What are the new locations of the coordinates after a dilation by a scale factor of 4?
Answer: A (-2,0) --> (-8,0)
B(-4,4) --> (-16,16)
C(1,6)--> (4,24)
Step-by-step explanation:
Multiply each coordinate by 4
A (-2,0) --> (-8,0)
B(-4,4) --> (-16,16)
C(1,6)--> (4,24)
The new locations of the coordinates after dilation by a scale factor of 4 as
A (-2,0) ⇒ (-8,0)
B(-4,4) ⇒ (-16,16)
C(1,6) ⇒ (4,24)
What is dilation?Dilation is a process for creating similar figures by changing the size.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
As we know dilation factor is the ratio of sides in the original image and the image after dilation.
Dilation factor = 4
Multiply each coordinate by 4
A(-2,0) ⇒ (-8,0)
B(-4,4) ⇒ (-16,16)
C(1,6) ⇒ (4,24)

(b) [tex]U_1 = 11[/tex]; [tex]U_2 =17[/tex]; [tex]U_{18} = 113[/tex]
Step-by-step explanation:
Required
1st, 2nd and 18th terms
To do this, we simply substitute 1, 2 or 18 for n in the given equations
Solving (a):
[tex]U_n =n^2 + 4[/tex]
1st term: n = 1
[tex]U_1 =1^2 + 4[/tex]
[tex]U_1 =1 + 4[/tex]
[tex]U_1 =5[/tex]
2nd term: n = 2
[tex]U_2 = 2^2 + 4[/tex]
[tex]U_2 = 4 + 4[/tex]
[tex]U_2 = 8[/tex]
18th term: n = 18
[tex]U_{18} = 18^2 + 4[/tex]
[tex]U_{18} = 324 + 4[/tex]
[tex]U_{18} = 328[/tex]
Solving (b):
[tex]U_n = 6n + 5[/tex]
1st term: n = 1
[tex]U_1 = 6*1 + 5[/tex]
[tex]U_1 = 6 + 5[/tex]
[tex]U_1 = 11[/tex]
2nd term: n = 2
[tex]U_2 = 6*2 + 5[/tex]
[tex]U_2 =12 + 5[/tex]
[tex]U_2 =17[/tex]
18th term: n = 18
[tex]U_{18} = 6*18 + 5[/tex]
[tex]U_{18} = 108 + 5[/tex]
[tex]U_{18} = 113[/tex]

Answer:
sinB
Step-by-step explanation:
Using trigonometric sum/difference rule -
we can expand the expression to
= (sinAcosB + cosAsinB)cosA - (cosAcosB - sinAsinB)sinA
= cosAsinAcosB + cos^2(A)sinB - sinAcosAcosB + sin^2(A)sinB
= cos^2(A)sinB + sin^2(A)sinB
= (cos^2(A) + sin^2(A))sinB, (Pythagorean identity)
= (1 * sinB)
= sinB
