Answer:
A.... X=3
Step-by-step explanation:
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
Hope this helped :D

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

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.

x=18
Since we wanna find the boys, we multiply the boys ratio with our x value.
2x=2•18=36 boys
Find the Area of the below triangles #s 1 & 2 (Show all work)
Area =
1. H = 4 in.
B = 15 in.
Area =
2. H = 8 in.
B = 15 in.
Answer:
1) 30 in²
2) 60 in²
Step-by-step explanation:
a = (1/2)bh
----------------------
h = 4
b = 15
a = 1/2 * 4 * 15
a = 30 in²
----------------------
h = 8
b = 15
a = 1/2 * 8 * 15
a = 60 in²
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.

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

x=cos(18)×800= 760.845≈ 761
Each envelope in the class contains the same number of triangles and quadrilaterals. Write an expression that
represents the total number of sides in the room.
Answer: 3t+4q.
Step-by-step explanation: Triangles have 3 sides, so there will be 3 sides for each triangle in the envelope. This is represented by 3t. Quadrilaterals have 4 sides, so there will be 4 sides for each quadrilateral in the envelope. This is represented by 4q. The total number of sides will be the number of triangle sides and the number of quadrilateral sides together.

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

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.
