find the value of x. (picture)
Answer:
x = 23
Step-by-step explanation:
Remember, angles in a triangle add up to equal 180
That being said we can create an equation to solve for x
180 = 110 + 35 + x + 12
now we solve for x
step 1: combine like terms
110 + 35 + 12 = 157
now we have 180 = 157 + x
step 2 subtract 157 from each side
180 - 157 = 23
157 - 157 cancels out
we're left with x = 23
Which function represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0)?
A) f(x) = - 7(x – 3) (x + 4)
B) f(x) = -6(x + 3) (x – 4)
C) f(x) = 8 (x-3) (x+4)
D) f(x) = 2 (x+3) (x – 4)
The function C represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0). Option C is correct.
What is a function, exactly?A function is a statement, rule, or law that establishes the connection between two variables. In mathematics, functions are everywhere and are necessary for constructing physical connections.
The general parabola equation is as follows: y=p (x-h)²+k or x=p(y-k)²+h, with (h,k) indicating the vertex.
The equation of the parabola is;
y=p (x-3)²+0
y=p(y-0)²+ (-4)
On combining both the equations;
f(x) = 8 (x-3) (x+4)
The function C represents a parabola that opens downward and intersects the x-axis at (3,0) and (-4,0).
Hence,option C is correct.

Is the proportion of the female population age 60 or older in country A greater than the proportion of the female proportion age 6 or older in country B
Answer:
Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.
Step-by-step explanation:
From. The plot given :
We could approximate the proportion of females older than 60 as follows _
COUNTRY A :
60 - 69 = 0.105
70 - 79 = 0.065
80 - 89 = 0.038
90+ = 0.01
Total = About 0.218
COUNTRY B :
60 - 69 = 0.14
70 - 79 = 0.11
80 - 89 = 0.07
90+ = 0.02
Total = About 0.34
From the estimated proportion, the proportion of females on country B is more than the proportion in country A.

Find the zeros of the function below, algebraically.
f(x)=(x-2)^2-64
Please show how you got answer and explain :D
Answer:
x=10 and x=-6
Step-by-step explanation:
f(x)=(x-2)²-64 (Given)
0=(x-2)²-64 (Set equation equal to 0)
64=(x-2)² (Add 64 to both sides)
±8=x-2 (Take the square root of both sides)
Because there are two possible roots, make 2 equations to find both:
8=x-2 and -8=x-2
10=x and -6=x

The national interest rate for savings accounts is 0.04%. I put $2,000 in my savings account for 40 years. How much interest will I earn?
Answer: $32.25
Step-by-step explanation:
Assuming this is compound interest, the value of the investment after a period of time can be calculated with the future value formula:
Value = Investment * ( 1 + rate) ^ no. of periods
Value ₄₀ = 2,000 * ( 1 + 0.04%)⁴⁰
Value ₄₀ = $2,032.25
Interest earned = Value at 40 years - Initial investment
= 2,032.25 - 2,000
= $32.25

What is the approximate area of a semicircle with radius of 21 ft? Use 3.14
Answer:
692 ft^2
Step-by-step explanation:
Area of a circle = (pi)(radius)^2
Here,
Area of the circle = (3.14)(21 ft)^2 = 1385 ft^2
Area of half this circle = area of the semicircle = 1385 ft^2 / 2, or
Area of semicircle = 692 ft^2
The surface area of a soccer ball is 254.5 in?.
What is the radius to the tenths' place?
Answer:
4.5 inches
Step-by-step explanation:
Use the formula for the surface area of a sphere, SA = 4[tex]\pi[/tex]r²
Plug in the surface area and solve for r, the radius:
SA = 4[tex]\pi[/tex]r²
254.5 = [tex]\pi[/tex]r²
20.25 = r²
4.5 = r
So, the radius is approximately 4.5 inches

Amy scheduled herself from 8am-1pm sunday through wednesday on wednesday she needed to release her intervals from 11am-1pm at the last minute she serviced all of the other time for which she posted what was her overall commitment adherence percentage?
Answer:
Commitment Adherence Percentage = 81.[tex]\overline{81}[/tex]%
Step-by-step explanation:
The time period Amy scheduled herself, t = 8 a.m. - 1 p.m. from Sunday through Wednesday
The period she released her interval = 11 a. m. - 1 p.m.
Commitment Adherence Percentage = Service Minutes/(Posted Minutes + Released Lockdown Minutes) × 100
Posted minutes = 5 hours/day × 60 minutes × 4 days = 1200 minutes
Serviced minute = 5 hours/day × 60 minutes × 3 days + 3 hours × 60 minutes/hour = 1,080 minutes
Released minutes = 2 hours × 60 minutes/hour = 120 minutes
Commitment Adherence Percentage = (1,080/(1,200 + 120)) × 100 = 81.[tex]\overline{81}[/tex]%

Last weekend, Abigail collected 7 times as many trading cards as Trey. Together, they collected 40 trading cards. How many trading cards did Abigail collect?
Answer: 35 trading cards
Step-by-step explanation:
Assume the trading cards collected by Trey is x.
That means that the number of trading cards collected by Abigail is 7x.
Relevant expression is:
7x + x = 40
8x = 40
x = 40/8
x = 5 trading cards
This means that Trey collected 5 trading cards
Abigail collected 7 times that figure so Abigail collected:
= 7 * 5
= 35 trading cards
