A pole casts a 6-foot shadow. If the distance from the top of the pole to the tip of the shadow is
10 feet, how many feet high is the pole?
a) 4
b) 8
c) 12
d) 16
e) 20
Answer:
8feet high
Step-by-step explanation:
To get the height of the pole, we will use the pythagoras theorem. Let H be the height
H² = 10² -6²
H² = 100 - 36
H² = 64
H = √64
H = 8feet
Hence the pole is 8feet high

F(x)=4x^2+3x+13
Find f(1)
Answer:
f(1) = 42
Step-by-step explanation:
Step 1: Switch all x out to 1 for f(1) which would look like this: f(1)=4(1)^2+3(1)+13
Step 2: You would then simplify it starting with 4(1)^2 which would equal 4 squared which equals 16.
Step 3: After simplifying you would have f(1)=16+3+13
Step 4: You then just add and get 42

4x = 2(x-5)-2 can you solve please
Answer:
x = -6
Step-by-step explanation:
4x = 2(x-5)-2
2 * x = 2x
2*-5 = -10
4x = 2x - 10 -2
4x = 2x - 12
4x - 2x = 2x
2x = -12
-12/2 = -6
x = -6
What are the domain and the range of this function?
•< •≤ •-5 •-4 •1 •7
D: ?, ? | X: ?, ?
R: ?, ? | Y: ?, ?
Answer:
The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} . Note that the domain elements 1 and 2 are associated with more than one range elements, so this is not a function.

The ratio of boys to girls is 2 to 3. If there are 90 students in the band, how many of them are boys?
Answer:
36
Step-by-step explanation:
We can make an algebric equation.

5x=90
x=18
Since we wanna find the boys, we multiply the boys ratio with our x value.
2x=2•18=36 boys

Why does the highest percent profit occur with the smallest annual interest rate?
Answer:
This is so because the higher the interest rate the lower the profit and the higher the total expenses and the percentage profit = (Profit/Expenses) × 100
Step-by-step explanation:
Question;
It is desired to find out the monthly percentage profit made to help decide the best loan option
Part A
Given that the monthly operating cost of the gym is 5,000 and the monthly sales is 7,500
Let 'I' represent the monthly interest paid on the loan, we have;
The percentage profit = Profit/(Total expenses) × 100
The total expenses = I + 5000
Profit = Sales - The total expenses
∴ Profit = 7,500 - (I + 5,000) = 2,500 - I
The percentage profit, P = (2,500 - I)/(5,000 + I) × 100
Therefore, as the interest rate becomes smaller, the numerator of the function for the percentage profit approaches its maximum value of 2,500 and the denominator approaches the minimum value of 5,000 and the percentage profit therefore, approaches the maximum value
Therefore;
The highest percentage profit occurs at the smallest interest rate.

The solutions of the of the equation are,
⇒ x = 3.12
⇒ x = 0.21
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ (3x - 5)² = 19
Now,
We can simplify the expression for the solutions as;
⇒ (3x - 5)² = 19
Take square root both side,
⇒ √(3x - 5)² = √19
⇒ (3x - 5) = √19
Add 5 both side,
⇒ 3x - 5 + 5 = √19 + 5
⇒ 3x = √19 + 5
⇒ 3x = ± 4.36 + 5
⇒ 3x = 4.56 + 5
⇒ 3x = 9.36
Divide by 3;
⇒ x = 9.36 / 3
⇒ x = 3.12
And, 3x = - 4.56 + 5
3x = 0.64
x = 0.64/3
x = 0.21
Thus, The solutions of the of the equation are,
⇒ x = 3.12
⇒ x = 0.21

You are constructing a 95% confidence interval using the information: n = 60, x-bar = 65.5, s = 2.5, and E = 0.70. What is the value in the middle of the interval?
Answer:
65.5
Step-by-step explanation:
Using the relation :
Xbar ± Margin of error
Margin of Error = Zcritical * s/√n
The Zcritical value at 95% = 1.96
Hence,
Margin of Error = 1.96 * 2.5/√60
Margin of Error = 1.96 * 0.3227486
Margin of Error = 0.6326
Lower boundary = 65.5 - 0.6326 = 64.867
Upper boundary = 65.5 + 0.6326 = 66.133
(64.867 + 66.133) / 2

Step-by-step explanation:
The circumference of a circle is given by
C = pi *d
The diameter is given by d=5
C = pi *5
If we use pi is approximated by 3.14
C = 3.14 *5 =15.7

Step-by-step explanation:
just use 1/2 x b x h
Answer:
Area of circle:
2^2 = 4
4 x 3.14 = 12.56
Area of two circles:
12.56 x 2 = 25.12
Now we find circumference:
2 x 3.14 x 2 = 12.56
Now we multiply it by height:
12.56 x 8 = 100.48
Let's add the given areas now:
100.48 + 25.12 = 125.6 cm2 is your answer.

The height of a cone is equal to three timesthe radius of the base. If the base has area 49 pie cm2, what is the volume of the cone?
Answer:
343pi^3
Step-by-step explanation:
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
h = height
Base area = area of a circle
Area of a circle = πr²
49 pi = πr²
r² = 49
r = 7
h = 7 x 3 = 21
volume = 1/3 x 21 x 7^2 = 343pi
