Answer:
±sqrt( (vf) ^2 -2ad)) = vi
Step-by-step explanation:
(vf) ^2 = (vi)^2 +2ad
Subtract 2ad from each side
(vf) ^2 -2ad = (vi)^2 +2ad -2ad
(vf) ^2 -2ad = (vi)^2
Take the square root of each side
±sqrt((vf) ^2 -2ad)) = sqrt((vi)^2)
±sqrt( (vf) ^2 -2ad)) = vi

Zeke goes to a skate shop with his friend Tristan. Tristan buys a helmet that costs $28.75. Zeke finds a helmet that is [tex]\frac{3}{5}[/tex] of the cost of Tristan's helmet. If Zeke gives the cashier a $20 bill, how much change will he receive.
Answer: $2.75

Zeke's helmet cost 3/5 x 28.75 = 17.25
Change = 20 - 17.25 = 2.75

Keith is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.
Company A charges $120 and allows unlimited mileage.
Company B has an initial fee of $75 and charges an additional $0.90 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Answer: m>50
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
The amount charged by company A (120) must be less (<) than the fixed amount charged by company B (75), plus the product of the cost per mile driven (0.90) and the number of miles driven (m).
120 < 75+ 0.90m
Solving for m:
120-75<0.90m
45<0.90m
45/0.90 <m
50<m
Company A charges less than Company B when m > 50.

Answer:

Step-by-step explanation:
6 length is 2 height.
So 10(6+4) length is 10/3 height
Answer:
x = 10/3
Step-by-step explanation:
These two triangles are similar by AA similarity, as they share angle A, and both have right angles.
Not we can set up a ratio:
6/(6+4) = 2/x
6/10 = 2/x
3/5 = 2/x
Multiply both sides by 5x,
3x = 10
Divide both sides by 3:
x = 10/3

Answer:
x=30°
Step-by-step explanation:
Angles 4x and 2x are supplementary, so 4x+2x must be equal to 180°.
Therefore, to solve this problem, we must use the equation, "4x+2x=180°.
4x+2x=180
6x=180
x=30°

Answer:
Step-by-step explanation:
Well, first of all the shape needs to be a rectangle not a square. And i think you do not understand how coordinates work.
The coordinate (-1, 4). The first number -1 is the number on the x-axis, 4 is the number on the y-axis. Same thing with the other coordinate.
After you put down the two dots, you know that the Perimeter is 24 cm.
P = 2(a + b) = 24 => a+b = 12 => a = 4 => b = 8
The sides are 4 and 8 units long.

The transformation for the given function is vertical compression or stretch.
The given functions are y=3x² and y=x².
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The graph for the given functions can be determined as follows
To find the transformation, compare the expression to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Horizontal Shift: None
Vertical Shift: None
Reflection about the x-axis: None
Reflection about the y-axis: None
Vertical Compression or Stretch: Compressed
Therefore, the transformation for the given function is vertical compression or stretch.

The height of trapezoid is 7km.
Step-by-step explanation:
Given that the area of trapezoid formula is A = 1/2×(a+b)×h where a and b represents the length and h is the height. By substituing the values, you are able to find the height :
[tex]area = \frac{1}{2} \times (a + b) \times h[/tex]
Let a = 4km,
Let b = 8km,
Let area = 42km²,
[tex]42 = \frac{1}{2} \times (4 + 8) \times h[/tex]
[tex]42 = \frac{1}{2} \times 12 \times h[/tex]
[tex]42 = 6 \times h[/tex]

Answer:
5/6x = -10
=> 5/6x = -10/1
by cross multiplication
=> 6x × - 10 = 5 × 1
=> 6x = 5 × 1 / -10
