Answers
Answer:
633.9 in.²
Step-by-step explanation:
Surface Area = Base Area + ½(Perimeter of Base)(slant height)
Base area = s² = 15.75² = 248.0625 in.²
Perimeter = 4(15.75) = 63 in.
Slant height = 12.25 in.
Surface area = 248.0625 + ½(63)(12.25)
= 633.9375 ≈ 633.9 in.² (nearest tenth)

Choose 1 answer:
B
m(x) = -2x² +24x54
-
m(x) = -2(x - 6)² + 18
m(x) = -2(x - 3)(x-9)
Write one of the zeros.
Answers
Answer:
m(x) = -2(x - 3)(x - 9)
One of the zeros of the function is x = 3
Step-by-step explanation:
The form that most quickly reveals the zeros (or "roots") of the function is:
m(x) = -2(x - 3)(x - 9)
To find the zeros of the function, we set m(x) equal to zero:
-2(x - 3)(x - 9) = 0
From this equation, we can see that the zeros (roots) of the function occur when either (x - 3) equals zero or (x - 9) equals zero. Solving these equations gives us the zeros:
x - 3 = 0
x = 3
x - 9 = 0
x = 9
Therefore, one of the zeros of the function is x = 3.

Niamh runs 6 km in 30-minutes what is the average speed in km h
Answers
Answer:
12 km/hr
Step-by-step explanation:
The average speed is 12 km/hr.
It is to find the average speed in km /h.
What is speed?Speed is measured as the ratio of distance to the time in which the distance was covered.
Given that :
Distance covered by Niamh = 6 km
Time =30minutes=30/60hour
=1/2hour
∴ The average speed=Total distance/Total time
The average speed=6*2/1
The average speed=12 km/hr.
So, the average speed is 12 km/hr.

Determine without converting the form and leave your answer in the form a+bi, where a,b ∈R
[tex]i^2^1(i+2)(i-3)\\\\\\\frac{(1+2i)(3+i)}{-2+i}[/tex]
Answers
The expression is in the form of a+bi where a,b ∈R. where, a = [tex]\frac{29}{5}[/tex]and b = [tex]\frac{-41}{5}[/tex] therefore, The complex number is [tex]\frac{29}{5}[/tex] [tex]-\frac{41i}{5}[/tex].
Given expression is:[tex]\frac{(i+2)(i-3)((1+2i)(3+i))}{(-2+i)}[/tex]
To simplify the above expression, first, we need to expand all the terms in the brackets which are given above.
We get,= [tex]\frac{(i^{2} - i*3 + 2i - 6) * (3 + i + 2i + 2i^{2} )}{(-2+i)}[/tex]
We know that i² = -1 and i²² = 1 and i*3 = 3i.
Therefore, the above expression becomes=[tex]\frac{(-1 -3i + 2i - 6) * (3 + i + 2i - 2)}{(-2+i)} =\frac{(-7 - i) * (5 + 3i)}{(-2 + i)}[/tex]
Now, we need to simplify the above expression by multiplying the numerator and denominator by the conjugate of the denominator.
Conjugate of -2 + i = -2 - i
Therefore, the expression becomes=[tex]\frac{(-7 - i) * (5 + 3i)*(-2 - i)}{((-2 + i)*(-2 - i))} = \frac{(-7 - i) * (5 + 3i)*(-2 - i)}{(4 + 1)} = \frac{(29 - 41i)}{5}[/tex]
The expression is in the form of a+bi where a,b ∈R. where, a = [tex]\frac{29}{5}[/tex]and b = [tex]\frac{-41}{5}[/tex]
Therefore, The complex number is [tex]\frac{29}{5}[/tex] [tex]-\frac{41i}{5}[/tex].

I will mark brainliest!!!Use the coordinate grid to determine the coordinates of point A A. What are the coordinates of point A?
Answers
Answer:
(-1/4, 1 3/4)
Step-by-step explanation:
The first thing to look at is the scale of the grid. To do that, look at the x-axis (horizontal). The space between 0 and 1 has been divided into 4 equal parts, so each part (square) is worth 1/4 in the horizontal directio.
The scale on the y-axis (vertical) is similar. Again, the space between 0 and 1 is divided into 4 equal parts, so each square represents 1/4 in the vertical direction.
To get to point A, begin at the origin, then go left one space. The x-coordinate of point A is -1/4. Now go up to point A, moving up through 7 spaces. The y-coordinate of point A is 7/4 = 1 3/4.
What is the vertex of the parabola
Answers
Answer:
lallalalaal hiiiiii
Step-by-step explanation:
The standard form is written as y = ax ^2 + b + c
Using the given equation:
A = -5, b = 30 and c = 7
The x value of the vertex = -b/ 2/a = -30/2(-5) = -30/-10 = 3
To find the y value replace x with the x value and solve for y:
Y = -5(3)^2 + 30(3) + 7
Y = -45 + 90 + 7
Y = 52
The vertex is (3,52)
The answer is G

229.22-57.3$171.92Answer:
$171.92
Step-by-step explanation:
Given information:
Weekly gross pay = $229.22Gross pay is the pay received before any deductions are taken.
Therefore, if 25% of deductions are taken from the given gross pay, the net pay will be 75%, since 100% - 25% = 75%.
Therefore, to calculate the expected weekly paycheck, find 75% of the gross weekly pay:
75% of $229.22
= 0.75 × 229.22
= 171.915
= $171.92
