This question is essentially asking one to find the vertex of the parabola formed by the given equation. One could plot the equation, but it would be far more efficient to complete the square. Completing the square of an equation is a process by which a person converts the equation of a parabola from standard form to vertex form.
The first step in completing the square is to group the quadratic and linear term:
[tex]h(t)=-5t^2 + 10t + 6\\\\h(t) = (-5t^2 + 10t) + 6[/tex]
Now factor out the coefficient of the quadratic term:
[tex]h(t)=-5(t^2 -2t) + 6[/tex]
After doing so, add a constant such that the terms inside the parenthesis form a perfect square, don't forget to balance the equation by adding the inverse of the added constant term:
[tex]h(t) = -5(t^2 -2t) + 6\\\\h(t) = -5(t^2 -2t + 1 -1 ) + 6[/tex]
Now take the balancing term out of the parenthesis:
[tex]\\\\h(t)=-5(t^2 -2t + 1) + 6 + ((-1)(-5))[/tex]
Simplify:
[tex]h(t) = -5(t^2 -2t + 1) + 6 + 5\\\\h(t) = -5(t-1)^2 + 11[/tex]
The x-coordinate of the vertex of the parabola is equal to the additive inverse of the numerical part of the quadratic term. The y-coordinate of the vertex is the constant term outside of the parenthesis. Thus, the vertex of the parabola is:

What restrictions are there on the range of the function H(w) below?
H(w)
(5.0,20.00)
A. H(w) s 1
B. H(w) > 0
C. H(w) < 0
D. There are no restrictions on the range of H(w).
Answer:
There are no restrictions on the range of H(w).
The restrictions that are there on the range of the function H(w) is:
Option B: H(w) > 0
How to Identify the Function restrictions?The function, named H(w) is defined by a graph that is a descendant line, that belongs only to the first quadrant.
As w approaches to 0 by the right, the function approaches to + infinity. It never touches the vetical axis, decreases and approaches to 0 when w approaches to infinity. The graph never touches the horizontal - axis.
Then, the function is defined only for positive values of w and H(w) is always positive.
Then, the answer is H(w) > 0, this is the option B

On a coordinate plane, a line goes through (0, 3) and (3, negative 1). A point is at (negative 3, 2).
What is the equation of the line that is parallel to the given line and passes through the point (−3, 2)?
Answer:
Step-by-step explanation:
Slope of line passing through (0, 3) and (3, -1) = (-1-3)/(3-0) = -4/3
Slope of any parallel to the line is also -4/3.
Point-slope equation for line of slope -4/3 that passes through (-3, 2):
y-2 = (-4/3)(x+3)
simplify 2(5+3x)+(x+10)
20+7x
just use the distributive property on 2(5+3x) then add x and 10

Answer: (-3, -8) (0, 1) (-3, -8)
Step-by-step explanation:
So in the equation, y=3x+1, 1 is the y intercept (which is where the line goes through the y intercept, so graph a point at 0,1 (that also fills out the middle of the chart. 3 is the slope of the equation so then you have to use the slope and you will find 2, 7 as a point and -3, -8 as a point.

The radius of a quarter circle is 3 millimeters. What is the quarter circle's area?
r=3 mm
Answer:
28.3mm
Step-by-step explanation:
3(3)=9(pi)= 28.274...
Answer: 9[tex]\pi[/tex], or more specifically, 28.26, or even more specifically, 28.2643.
Explanation:
To find the area of a circle, you need to do r squared x pi. Since pi repeats randomly infinitely, we are going to simplify it to 3.14. 3 squared or 3 x 3 equals 9. 9 x 3.14 = 28.26. Therefore, the area of the quarter is 28.26. If you want to find the answer without simplifying pi, it is approximately 28.2643. You can also write it as 9[tex]\pi[/tex].

Question: pentagon STUVW is similar to S' T' U' V' W'. angle U=56 degrees, angle U' = 3x-16, and Angle T'=x+46. ST=57, UV=63, S' T'=19 and U' V' =y+4
a. Find x
b. find angle T'
c. Find y
you have to do, a, b, and c
Answer:
Similarity doesn't changes angle measures
∠U = 56°, ∠U' = 3x - 16∠U = ∠U'a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°
b) ∠T = x + 46 = 24 + 46 = 70°
c) Scale factor:
k = S'T'/ST = 19/57 = 1/3Find y using known sides and scale factor:
U'V'/UV = 1/3(y + 4)/63 = 1/3y + 4 = 21y = 21 - 4y = 17[tex]\frac{\sqrt[3]{60} }{\sqrt[3]{36} }[/tex]

Determine the missing side length:
I will give 25 points for the answer!!!!!!!!
Answer:
3
Step-by-step explanation:
Use Pythagorean theorem
Base²+ altitude² = hypotenuse²
Base² + (√3)² = (2√3)²
Base² + √3 *√3 = 2√3 *2√3
Base² + 3 = 4*3
Base² + 3 = 12
Base² = 12 - 3
Base² = 9
Base = [tex]\sqrt{9}=\sqrt{3*3} =3[/tex]
