Answer:
(x²+8x+16)π in²
Step-by-step explanation:
Since were not given the diagram of the circle. Let's assume the radius of inner circle is x+4
radius r = x+4
Area of the circle = πr²
Area of the circle = π(x+4)²
Area of the circle = π(x+4)(x+4)
Area of the circle =π(x²+4x+4x+16)
Area of the circle = π(x²+8x+16)
Area of the inner circle in terms of pi is (x²+8x+16)π in²
One hundred deer were released into a wildlife preserve. The population of deer over a certain number of years is shown.
What degree polynomial could be used to model these data?
Answer:
Quartic
Step-by-step explanation:
The missing dataset showing the population of deer is shown below:
[tex]\text{Time (years) \ \ \ \ 0 \ \ \ \ 0.5 \ \ \ \ 1 \ \ \ \ 1.5 \ \ \ \ 2 \ \ \ \ 2.5 \ \ \ \ 3 \ \ \ \ 3.5 \ \ \ \ 4}[/tex]

The degree of polynomial best suitable to model the above dataset is Quartic
[tex]\text{Quartic is an algebraic equation or function of the fourth degree }[/tex]
The polynomial model of the above data is:

There are 8 students on the school chess team. They need to raise at least $760 for a field trip. Their advisor says they still need to raise 85% of the funds, and she wants each of them to raise an equal share of the money still needed. Diego wrote and solved the inequality 8m + 0.85(760) ≥ 760 to find the least amount of money, m, each student on the chess team needs to raise. He says the solution is m ≥ $14.25. Diego is incorrect.

Answer:
Look below!
Step-by-step explanation:
Angle A = 180-47 = 133
Angle B = 180-32-Angle A = 180-32-47 = 101
Angle D = 90-32 = 58
Angle C = 180-47-58 = 75
Hope I helped!
Answer:
A=133 ,B=15, C=75 D= 58
Step-by-step explanation:
Angle 32, d, and right angle add up to 180. So 180=32+90+x. Then x = 58 (D). The all 3 angles in the triangle add up too 180 so 180=47+58+x. x=75 (C). The 47 and a equal to 180 degrees. 180-47=133. The 133+32+x=180. x=15 (B).

Step-by-step explanation:
You are doing ratios
please help solve for x ................................................................
Answer:
104°+33°+(5x+13)°=180°[all angle sum is 180°]
137°+(5x+13)=180°
137°+13+5x=180°
150°+5x=180°
5x=180°-150°
5x=30
x=30/5
×=6
Answer:
x = 6
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
5x + 13 + 104 + 33 = 180, that is
5x + 150 = 180 ( subtract 150 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6

What is the cost of paving the path with bricks at rate of Rs.100 per m². When area of land is 63 m s
Answer:
Rs. 6300
Step-by-step explanation:
Given that:
Land area = 63m²
Rate of paving brick = RS. 100 per m²
Hence, to pave bring on a 63m² land area ;
Total cost of paving brick will be :
Cost per m² * land area
Rs. 100 * 63
= Rs. 6300
