[tex]\boxed{Explanation}[/tex]
So, we have the following equation...
[tex]5^2+20=(?)[/tex]
Remember, 5² also means 5x5.
Therefore, [tex]5x5=25\\25+20=45[/tex]
This means your final answer is 45.

Which number is not a perfect square?
(A) 1
(B) 25
(C) 30
(D) 36
Answer:
Hello! :) I hope I’m correct!!
Step-by-step explanation:
I think (C) 30 is not a perfect square.
(A) 1 = perfect square
(B) 25 = perfect square
(C) 30 = NOT a perfect square
(D) 36= perfect square
{Note: The square root of 30 is not an integer, so therefore 30 is not a square number}
Since the question is asking to find a number that is NOT a perfect square...
The answer would be (C) 30
Hope this helps! If you have any questions about this, feel free to ask! Have a wonderful day! ^-^

A cone is shown
What is the approximate volume of the cone?
A.
120 cubic inches
B.
628 cubic inches
C.
1,884 cubic inches
D.
2,512 cubic inches
Answer: 628.32 inch cubed
Step-by-step explanation:
Formula for volume of a cone: 1/3 x area of base x height
Area of base: pi x radius squared
= pi x 10 squared
= 314.16
Now, 1/3 x 314.16 x 6
= 628.32
Answer:
Answer:
B
Step-by-step explanation:
[tex]Known\ by\ the\ graphic,\ r=\frac{1}{2}\bullet20=10,\ h=6[/tex]
[tex]V=\frac{1}{3}[/tex]π[tex]r^2[/tex]·h[tex]=200\pi\approx628[/tex]

5. number of terms
6. degree
7. leading coefficient
8. end behavior
9. turning point(s)
10. x-intercept(s)
11. relative minimum(s)
12. relative maximum(s)
Answer:
5 terms
to the fourth degree
leading coeff of 1
3 turning points
end behavior (when x -> inf, y -> inf. When x -> - inf, y -> -inf)
x intercepts are (0,-4) (0,-2) (0,1) (0,3)
Relative min: (-3.193, -25) (2.193, 25)
Relative max: (-0.5, 27.563)
Step-by-step explanation:
The terms can be counted, seperated by the + and - in the equation given.
The highest exponent is your degree.
The number before the highest term is your leading coeff, if there is no number it is 1.
The turning points are where the graph goes from falling to increasing or vice versa.
End behaviour you have to look at what why does when x goes to -inf and inf.
X int are the points at which the graph crosses the x-axis.
The relative min and max are findable if you plug in the graph on desmos or a graphing calculator.

The equation the function after the transformation is g(x) = -4x² - 16
What is transformation?Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.
here, we have,
to determine the transformation of the function:
The equation of the function is given as
f(x) = x²+2
The sequence of transformations is given as follows:
Translate up by 2 units
Reflection across the x-axis
Vertically stretched by a factor of 4
When the above transformations are combined, we have:
Translate up by 2 units: g(x) = f(x) + 2
Reflection across the x-axis: g(x) = -(f(x) + 2)
Vertically stretched by a factor of 4: g(x) = -4(f(x) + 2)
So, we have
g(x) = -4(x²+2 + 2)
Expand
g(x) = -4x² - 16
Hence, the function g(x) is g(x) = -4x² - 16

A chair can be purchased in one of four colors: red, white, green, or blue. The number of chairs purchased in each color is listed below. Red: 150 white: 450 green: 225 blue: 375 Based on the information shown in the list, what is the probability that the next chair purchased will be red?
Answer:
[tex]P(Red) = 0.125[/tex]
Step-by-step explanation:
Given
[tex]Red: 150[/tex]
[tex]White: 450[/tex]
[tex]Green: 225[/tex]
[tex]Blue: 375[/tex]
Required
Determine the probability of getting a red chair, next.
First, we nee the total number of chairs
[tex]Total = 150 + 450 + 225 + 375[/tex]
[tex]Total = 1200[/tex]
Probability of getting red is then calculated as thus;
[tex]P(Red) = Red/Total[/tex]
[tex]P(Red) = 150/1200[/tex]
[tex]P(Red) = 0.125[/tex]

Answer:
oranges $3.50 per Kg, bananas $3 per Kg
Step-by-step explanation:
let b represent cost of bananas and o represent cost of oranges , then
2b + 3o = 16.5 → (1)
o = b + 0.5 → (2)
substitute o = b + 0.5 into (1)
2b + 3(b + 0.5) = 16.5 ← distribute parenthesis on left side and simplify
2b + 3b + 1.5 = 16.5
5b + 1.5 = 16.5 ( subtract 1.5 from both sides )
5b = 15 ( divide both sides by 5 )
b = 3
substitute b = 3 into (2)
o = 3 + 0.5 = 3.5
cost of oranges = $3.50 and cost of bananas = $3
if the points (0,4) and (2,8) lie on the same line what is the rate of change of the line. I WILL GIVE BRAINLIST!!!
Answer:

change in x = 2-0 = 2
4 / 2 = 2
4. Shelton earns an hourly wage at a grocery store. The following expression represents Shelton’s take home pay after taxes, social security, and his health care plan are deducted. Let x represent the number of hours Shelton worked.
10.25x − 0.21(10.25x)
a) Which term represents Shelton’s total pay before deduction?
b) Shelton wants to save $1,675 for a new laptop. If Shelton saves 25% of his take-home pay, how many hours will he need to work to meet his savings goal?
Answer:
a) Shelton’s total pay before deduction: 10.25x
b) To meet savings goal he'll have to work 827.415869 hours.
Step-by-step explanation:
Take-home pay:
10.25x − 0.21(10.25x)
10.25x − 2.1525x
8.0975x
Save 25% for new laptop:
.25(8.0975x) = 1675
2.024375x = 1675
x = 827.415869 hours

Can you say if each statement is true or false
2. Counter statements like sum += 1 are often used in the body of for loops.
3. A for loop with the header for i in range(1, 5): would iterate exactly 5 times.
4. A for loop with the header for i in range(4, 10, 2): would iterate exactly 6 times.
5. The for loop with the header for i in range(4): would iterate exactly 4 times.
6. The statement sum += 1 is equivalent to the statement sum = sum + 1 True
7. A good name for a for loop's control (or loop) variable would be z.
8. A for loop is considered to be a definite loop.

f(x) = 3x + k
f(4) = 10
easy equation but I just need a confirmation that the answer is actually -2 lol
Answer:
-2
Step-by-step explanation:
f(x) = 3x + k
f(4) = 10
f(4) = 3×4+k
10 = 12 + k
10-12 = k
k = -2

x+4y=9
if x = y+4
Answer:
4x + 8y =12 [inconsistent]
x + 2y = -3
x = 6 [inconsistent]
x = -2
2y = 5x + 6 [inconsistent]
-10x + 4y = 8
x - 3y=2
4x - 12y = 8 [dependent]
x+ 4y = 12 [independent]
2x - 8y = 4
4x + 8y = -6 [dependent]
6x + 12y = -9
4y - 2x = 6 [inconsistent]
8y = 4x -12
y - x = 0 [independent]
y = -x
2y - x = 4
