Answer:
y=-2(x+8)²-7
Step-by-step explanation:
Given: y=-2x²+5
After transformations: y=-2(x+8)²-7
Vertex would be (h,k) -> (-8,-7) instead of (0,5)
The function f(t) = 790(0.994) 60t represents the change in a quantity over t
hours. What does the constant 0.994 reveal about the rate of change of the quantity?
Answer:
Please check explanations
Step-by-step explanation:
From what we have, the constant term is 0.994
Now, what this mean is that with an increase in the value of t, there will be a decrease in the change of quantity
This is because the rate of change is less than 1
With an increasing value of power, the value of the exponent would be less than its previous value
So what this mean is that we would have less quantities over time since the value of the constant term is less than 1

Answer:
A circle is a round shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.
The distance from the center to the circumference of a circle
The diameter is the length of the line through the center that touches two points on the edge of the circle.
The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
In plane geometry, a chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle.
A line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. The diameter is twice the size of the radius. A line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. A circle is the same as 360°.
A line that intersects two or more points on a curve. (From the Latin secare "to cut")
The length of the side opposite the angle divided by the length of the adjacent side.
A line that intersects a circle in exactly one point is called a tangent and the point where the intersection occurs is called the point of tangency. The tangent is always perpendicular to the radius drawn to the point of tangency. A secant is a line that intersects a circle in exactly two points.
Common tangents to two circles may be internal or external. A common internal tangent intersects the line segment connecting the centers of the two circles whereas a common external tangent does not.

c
C. V2
2
D.
2
Answer:
C
Step-by-step explanation:
Short explanation:
Using the unit circle, the answer is C.
If you want a full in depth, answer:
The unit circle has a radius of 1.
3pi/4 is located in the 2nd quadrant.
That radian measures 135 degrees.
The 2nd quadrant start after 90 degrees.
To find the terminal angle, subtract 90 from 135.
Which gives you 45.
This means we are dealing with a 45-45-90 triangle.
Since our hypotenuse is 1, our y and x have to be
[tex] \frac{ \sqrt{2} }{2} [/tex]
Sin is positve in the 2nd quadrant so C is the answer.
Determine if each pair of triangles is congruent. If so, write the congruence

Derrick started a new job at McDonald's. He makes $10 per hour. Which
equation models his total weekly earnings y, in terms of the number of
hours he works x? *
Answer:
10x=y.
Step-by-step explanation:
10 represents the amount he earns an hour. X represents the number of hours so 10x. 10 times the amount of hours equals y (total amount of money)
Answer:
y = 10x
Step-by-step explanation:
The total earnings, y, is equal to the hourly rate, 10, times x, the hours worked.
y equals 10 times x, or, in equation form, y = 10x.

An engineer is designing a fountain that shoots out drops of water. The nozzle from which the water is launched is 3 meters above the ground. It shoots out a drop of water at a vertical velocity of 14 meters per second. Function h models the height in meters, h, of a drop of water t seconds after it is shot out from the nozzle. The function is defined by the equation h(t)=−5t2+14t+3. How many seconds until the drop of water hits the ground?
Answer:
After 3 seconds
Step-by-step explanation:
Given
[tex]h(t) = -5t^2 + 14t + 3[/tex]
Required
Time the drop will hit the ground
When the drop hits the ground,
[tex]h(t) = 0[/tex]
So, we have:
[tex]0 = -5t^2 + 14t + 3[/tex]
Rewrite as:
[tex]5t^2 - 14t - 3 = 0[/tex]
Expand
[tex]5t^2 + t - 15t - 3 = 0[/tex]
Factorize
[tex]t(5t + 1) -3(5t + 1) = 0[/tex]
Factor out 5t + 1
[tex](t -3)(5t + 1) = 0[/tex]
Split
[tex]t -3 = 0[/tex] or [tex]5t + 1 = 0[/tex]
Solve for t
[tex]t = 3[/tex] or [tex]5t = -1[/tex]
Time cannot be negative.
So:
[tex]t = 3[/tex]

aurav went to school for 216 days in a full year. If his attendance is 90%, find the number of days on
which the school was open.
Answer:
The school was open for 240 days
Step-by-step explanation:
216 / x = 90%/100%
216*100= 21,600
21,600/90 = 240
Which function has the same range as
f(x)= -2sqrt (x-3)+8
Answer:
Answer: : g(x)=-sqrt(x+3)+8
Step-by-step explanation:
The function has the same range is the third one:
g(x)=-sqrt(x+3)+8
The range of this function is:
x+3>=0
sqrt(x+3)>=sqrt(0)
sqrt(x+3)>=0
Multiplying the equation by -1:
-1[ sqrt(x+3)>=0]
- sqrt(x+3)<=0
Adding 8 both sides of the equation:
- sqrt(x+3)+8<=0+8
- sqrt(x+3)+8<=8
g(x)<=8
Then Range g(x)= (-Infinite, 8]
Answer: Third option: g(x)=-sqrt(x+3)+8
Two wires are attached 6 feet up a tree and 3 feet from the base of the tree. About how much TOTAL wire was used?
Answer:
9 cm²
Step-by-step explanation:
Two wires are attached 6 feet up a tree and 3 feet from the base of the tree. About how much TOTAL wire was used?
We solve the above question, using the Area of a Triangle
Area = 1/2 × Base × Height
Area = 1/2 × 3 × 6
Area = 9 cm²
Therefore, the total wore that was used was 9cm² of wire

What is the area in square centimeters of the trapezoid below
Answer:
39.6 cm²
Step-by-step explanation:
The formula for the area of a trapezoid is given as:
Area of a Trapezoid = 1/2(a + b) h
Where, from the question:
a = 8.9 cm
b = 5.5 cm
h = 5.5cm
Hence,
1/2 (8.9cm + 5.5cm) × 5.5cm
= 1/2 × 14.4 cm × 5.5 cm
= 39.6 cm²
Area of the Trapezoid = 39.6 cm²
Find the area of the given shape.

Solve. 1/2(4x + 2/5) = 4/5
Answer:
[tex]\frac{1}{2}(4x + \frac{2}{5} ) = \frac{4}{5}\\2x + \frac{1}{5} = \frac{4}{5}\\\frac{10x + 1}{5} = \frac{4}{5}\\10x + 1= 4\\10x = 3\\x = \frac{3}{10}[/tex]
Answer:
x = 3/10
Step-by-step explanation:
Given equation,
→ 1/2(4x + 2/5) = 4/5
Let's solve the problem,
→ 1/2(4x + 2/5) = 4/5
→ 2x + (1/5) = 4/5
→ 2x = (4/5) - (1/5)
→ x = (3/5) × (1/2)
→ [ x = 3/10 ]
Thus, the value is 3/10.
What is the difference between the number of solutions for a two-step equation and for a two-step inequality
Answer:
A two-step equation is something like:
A*X + B = C
In this case, like in a linear equation, we have only one solution that can be found as:
A*X = C - B
X = (C - B)/A
In the case of a two-step inequality, we have something like:
A*X + B > C
Solving this we get;
A*X > C - B
X > (C - B)/A
In this case, any value of X that is larger than (C - B)/A is a solution, so in this case, we have infinite solutions.
That is the difference between the number of solutions for each case, in a two-step equation we have only one, while in the case of the inequality we have infinite.

Each container has a base of 4 1/4 yds by 1 2/3 yds. What is the area covered by all the containers?
Answer:
See Explanation
Step-by-step explanation:
Given
Base Dimension
[tex]Length = 4\frac{1}{4}yd[/tex]
[tex]Width = 1\frac{2}{3}yd[/tex]
Required
The base area of all containers
First, calculate the base area of 1 container.
This is calculated as:
[tex]Area = Length * Width[/tex]
[tex]Area = 4\frac{1}{4}yd * 1\frac{2}{3}yd[/tex]
Express as improper fraction
[tex]Area = \frac{17}{4}yd * \frac{5}{3}yd[/tex]
So, we have:
[tex]Area = \frac{17*5}{4*3}yd^2[/tex]
[tex]Area = \frac{85}{12}yd^2[/tex]
The number of containers is not given. So, I will use 'n' as the number of containers.
So, we have:
[tex]Total = n * Area[/tex]
[tex]Total= n * \frac{85}{12}yd^2[/tex]
--------------------------------------------------------------------------------------------
Assume n is 3 (i.e. 3 containers)
The total area is:
[tex]Total= 3 * \frac{85}{12}yd^2[/tex]
[tex]Total= \frac{85}{4}yd^2[/tex]
[tex]Total= 21\frac{1}{4}yd^2[/tex]

HI thts way tooo much to answer but ye
A door is fixed at the point O. Ben opened it by an angle of 30°. The area swept by the door was {25}{12}\pi\
Answer:
5 units
Step-by-step explanation:
Area swept by the floor will be the area ofd a sector
Area of a sector = theta/2π * πr²
We are to find the radius r
Given
Area= 25π/12
theta = 30° = π/6
Substitute
25π/12 = 30/360 * πr²
25π/12 = 1/12 * πr²
25/12 = r²/12
r² = 25
r = √25
r = 5
Hence the radius od the part swept by the door is 5 units
