A car approaches a stop sign going 10 m/s before coming to a stop. If it takes 5 seconds to
do this, what is its acceleration
Answer:
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
Step-by-step explanation:
Given
Initial velocity u = 10 m/sFinal velocity v = 0Time taken t = 5 secondsTo determine
Acceleration a = ?
Using the formula to determine the acceleration
a = (v - u) / t
substituting u = 10 m/s, v = 0 and t = 5
a = (0 - 10) / 5
a = -10 / 5
a = -2 m/s²
Thus,
The acceleration is: a = -2 m/s²
The negative sign indicates that velocity is decreasing with time.
Write the equation of the line parallel to 4x - y = 5 and passes through (3, 4)
Answer:
Equation of the line parallel to 4x - y = 5 and passes through (3, 4) is
[tex]y=-4x+16[/tex]
Step-by-step explanation:
Slope of line 4x - y = 5 is -4. Since parallel lines have same slopes therefore slope of other line is -4 as well.
Equation of the line that passes through (3, 4) and has slope -4 is given as
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-4=-4(x-3)[/tex]
Simplifying it further
[tex]y=-4x+12+4[/tex]
[tex]y=-4x+16[/tex]

Jessica open a savings account. In 3-month period, she makes deposit of $25.50 and $45.25. She makes with drawls of $15.15 and $28.65. Her balance at the end of a three month period is $115.85. Explain how you can find her initial deposit amount. Show your work
Answer: $88.90
Step-by-step explanation:
Let her initial deposit be represented by x.
Based on the information given, in the question, an equation can be formed as:
x + $25.50 + $45.25 - $15.15 - $28.65 = $115.85
x + $70.75 - $43.80 = $115.85
x = $115.85 + $43.80 - $70.75
x = $88.90
The initial deposit is $88.90
write an equation in point-slope for the line through the given point with the given slope.(2,6); m=3/2
Answer:
y-6=3/2(x-2)
Step-by-step explanation:
point slope form is y-y1=m(x-x1), where m is the slope and (x1,y1) are numbers.
we have the slope (m) given as 3/2, and the point given as (2,6)
substitute the numbers into the equation
y-6=3/2(x-2)

Step-by-step explanation:
Given: Kristen made 4 out of 5 throws in her first basketball game, 5 out of 8 in her second game and 5 out of 7 free throws in her third game.
To Find: The experimental probability of Kristen marking her first free throw in her fourth game.
Solution:
There are only two possibilities that the first throw will be free or not.
Hence, the total outcomes = 2
Hence, Probability that the throw is free = [tex]\frac{1}{2}[/tex]
Hence, 1/2 is the experimental probability of Kristen marking her first free throw in her fourth game.

1. Write an equation in point-slope form of the line that that passes through the point (4,-5) and has a
3/2
Answer:
y + 5 = (3/2)(x - 4)
Step-by-step explanation:
The point-slope formula is y - k = m(x - h). We get h and k from the given point: h = 4 and k = -5, and m from the given slope: 3/2. Then we have:
y + 5 = (3/2)(x - 4)

Burgers come in packages of 15, and buns come in packages of 6. You want to serve Keto burgers on buns and wants to have no items left. How many of each item will you have to buy?
Answer:
2 package burgers, and 5 package buns
Step-by-step explanation:
Let us find the least common multiple of 15 and 6, which is 30!
If you buy 30 burgers, you would buy two packages (30/15=2)
If you buy 30 buns, you would buy 5 packages (30/6=5)
You would also have No items left over!

Nicky wants to surround a painting 5 inches by 11 inches with a frame that is w inches wide. Write a quadratic function A in standard form to represent the combined area A of the picture and the frame.
A(w) = w2 + w +
Answer:
Since the frame is uniform around the picture, you need to add its width, W, to the sides of the picture. We will manipulate the formula for area, A = L x W. To ease confusion with the chosen variable, I will replace the W with an H for height to be A = L x H.
L = W + 11 + W
H = W + 5 + W
You can see this by drawing a picture with a frame around it. Looking from the top to the bottom, you will have it's width plus the picture plus the width of the frame again. Same thing for the height of the picture. Looking from the far left of the frame and across, you have the width of the frame plus the picture plus the width of the frame again. Now plug these into the area formula and combine like terms.
A = L x H
A = (W + 11 + W) x (W + 5 +W)
A = (2W + 11) x (2W + 5)
Now take the product of the two parenthesis.
I learned to use the FOIL method: multiply First, Outside, Inside, Last.
A = (2W x 2W) + (2W x 5) + (11 x 2W) + (11 x 5)
A = 4W2 + 10W + 22W + 55
A = 4W2 + 32W + 55
Step-by-step explanation:
The quadratic function A in standard form to represent the combined area A of the picture and the frame is 4w²+32w+55.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
Nicky wants to surround a painting 5 inches by 11 inches with a frame that is w inches wide.
Then, the width of the painting
w = 5 + w + w
=2w+5 (w inches wider on both sides)
and, the length of the painting
l = 11 + w + w = 2w+11
So, the area is
Area = length x width
= (2w+11)(2w+5)
=4w²+22w+10w+55
= 4w²+32w+55

what is the slope and y-intercept for the line y = -2x
Answer:
slope = - 2, y- intercept = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x , that is
y = - 2x + 0 ← is in slope- intercept form
with slope m = - 2 and y- intercept c = 0 ( that is the origin )

Please help!! I need it and I don’t know what to do. (Ignore the blue dot btw)
Answer:
1 foot / 7.2 yards
Step-by-step explanation:
So all you have to do is set up a ratio, and then simplify.
You start with 25 feet / 180 yards.
Then, you can divide both parts of this ratio by 5 and it will still be equal.
(25 feet/5) / (180 yards / 5) = 5 feet / 36
Then, you divide both sides by 5 again:
(5 feet / 5) / (36 yards / 5) = 1 foot / 7.2 yards
