Use POE to eliminate answers that are not correct. Plug 1,2,3,4 into n for each of the sums, and see if they give you 0+2+6+12. Only D does this.
In 1990 Detroit, Michigan, had an estimated population of 1,027,974. By 2000 the population had decreased 7 1/2%. What was the estimated population in 2000 for Detroit, Michigan? Find the answer to the nearest whole number.
Answer:
950876
Step-by-step explanation:
- the population had gone down 7.5%, that means 92.5% of the population remained [ 100 - 7.5 = 92.5 ]
- 92.5% of the original population is
( 92.5/100 ) * 1,027,974
- calculate and you'll get = 950875.95
- rounded up, its 950876

Captain America's circular shield has a diameter of 76.2 centimetres. What is the area of his shield?
Answer:
4560.37
Step-by-step explanation:
A= 1 /4 x π x 76.2²
Brainliest?????
The area of the Captain America's circular shield is 4560.36 cm²
From the question,
We are to determine the area of Captain America's circular shield, which has a diameter of 76.2 cm.
To do this,
We will use the formula for finding the area of a circle.
The formula for the finding the area of a circle is
[tex]A = \pi r^{2}[/tex]
Where, A is the area
and r is the radius of the circle
From the question
Diameter of the circular shield = 76.2 cm
First, we will determine the radius of the circular shield
From
[tex]Radius = \frac{Diameter}{2}[/tex]
∴ Radius of the circular shield = [tex]\frac{76.2}{2}[/tex] cm
Radius of the circular shield = 38.1 cm
Now, for the area of the shield
r = 38.1cm
∴ Area of the shield = [tex]\pi \times 38.1^{2}[/tex]
Area of the shield = 1451.61π
(Take π = 3.14159)
∴ Area of the shield = 1451.61 × 3.14159
Area of the shield = 4560.36 cm²
Hence, the area of the circular shield is 4560.36 cm²

3. Sum of digits of a two digit number is 14. When 18 is added to the original number, then the new number is obtained by exchanging the digits of the original number. Express the statements in equation.
Answer:
let the numbers be xy
general form of the number =10x+y
sum of digits of a number =14
x+y=14………[1]
if 18 is added to the number, then digits are interchanged
10x+y+18=10y +x
9x-9y=-18
X-y=-2………[2]
the linear equations are 1) x+y=14
2) X-y=-2
adding [1],[2]
2x=12
x=6
x+y=14
y=14-x
y=14-6
y=8
there fore the number =10*6+8
=68
check:-
1)6+8=14
2)68+18=86

Put 2y= -3x = 5 in standered form
Answer:
3x + 2y = 5
Step-by-step explanation:
Given: 2y= -3x + 5 (assuming the sign before 5 is + instead of =)
for standard form, it has to be in ax + by = c
2y = -3x + 5; add 3x to both sides
3x + 2y = 5

Let f(x) = 4x + 3 and g(x) = -2x + 5. Find.(f.g)(5)
a. 23
b. -17
c. -41
d. -5
Answer:
After solving we get (f.g)(5)=-115
But the correct option is not given in the question.
Step-by-step explanation:
We are given:
[tex]f(x) = 4x+3\\g(x)=-2x+5[/tex]
We need to find (f.g)(5)
First we will multiply f and g to find (f.g) i.e
[tex](f.g)(x)= f(x) \times g(x)\\(f.g)(x) = (4x + 3)(-2x + 5)\\(f.g)(x)=4x(-2x+5)+3(-2x+5)\\(f.g)(x)=-8x^2+20x-6x+15\\(f.g)(x)=-8x^2+14x+15\\[/tex]
Now putting x=5
[tex](f.g)(x)=-8x^2+14x+15\\Put \ x=5\\(f.g)(5)=-8(5)^2+14(5)+15\\(f.g)(5)=-8(25)+70+15\\(f.g)(5)=-200+70+15\\(f.g)(5)=-115[/tex]
So, after solving we get (f.g)(5)=-115
