This scatter plot shows the association between time elapsed and distance left to go when John drove from city A to city B. What are the slope
and the y-intercept of the line of best fit on the scatter plot?
Answer:
The y intercept is 80 and the line of the best fit is -3/5
Step-by-step explanation:
The y intercept of the line of best fit is 80 miles with a slope of -0.6 mile per minute
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the graph, the y intercept is 80 miles. The line passes through (0, 80) and (100, 20), hence:
slope = (20 - 80) / (100 - 0) = -0.6 mile per minute
The y intercept of the line of best fit is 80 miles with a slope of -0.6 mile per minute

Evaluate the expression when x=-6.
x² + 5x-5
Answer:
1
Step-by-step explanation:
x² + 5x-5
Let x = -6
(-6)^2 + 5(-6) -5
36 -30 -5
6-5
1
To evaluate the expression x² + 5x - 5 for x=-6, substitute -6 into the expression and follow the order of operations to obtain a result of 1.
Substitute -6 for x in the expression, which gives us (-6)² + 5(-6) - 5.Calculate the square of -6, which is 36.Multiply 5 by -6, which is -30.Add these results and subtract 5: 36 - 30 - 5 = 1.Therefore, the value of the expression when x = -6 is 1.

First, she needs to find her resting heart rate by counting her pulse for one minute immediately after she wakes up for 5 days in a row. She finds her average resting heart rate to be 62 after
5 days and she remembers the last day's pulse was 58 and all the others were the same. Write and solve an equation to find what her pulse was on all the other days. Justify your answer by showing your steps. Put in Simple equation
Answer:
63
Step-by-step explanation:
She finds her average resting heart rate to be 62 after 5 days.
That means, average of the 5 heart rate pulse=62
If the last day was 58 and all the other days were the same.
Let x be her pulse on the other days,
Then,
[tex]Average, 62=\dfrac{58+4x}{5}\\\text{Cross Multiply}\\58+4x=62 X 5\\\text{Suntract 58 from both sides}\\4x=(62X5)-58\\4x=310-58\\4x=252\\\text{Divide both sides by 4}\\x=63[/tex]

What is the value log5 25?
Answer:
2
Step-by-step explanation:
You can think of logarithms as a rewritten exponent.
So exponents are in the form of a^b=c
Logarithms are [tex]log_a c=b[/tex]
Here, we have [tex]log_{5} 25[/tex]
Basically we have to figure out 5 to the power of what is 25.
So our answer is 2.
5^2=25
The value of log5 25 is 2, as 5 to the power of 2 equals 25.
The value of log₅ 25 is determined by asking the question: 'to what power do we need to raise 5 to get 25"
Since 5 squared is 25 (5² = 25).
The power of 5 is 2.
Therefore, log₅ 25 = 2
Frank averages a speed of 19 miles per hour during his bike race. The race is 60 miles long.
Answer:
3 hours and 16 minutes or 3.16 for Frank to finish the race
Step-by-step explanation:
60 miles long Frank is going 19 miles an hour
60 divided by 19 3.157 rounded up 3.16
Using the distance and speed, we calculate the time it takes for Frank to complete the bike race. He averages a speed of 19 miles per hour for a 60-mile race, which means it will take him approximately 3.16 hours to finish.
Explanation:This question is about solving a typical problem in math - specifically, calculating time with information on distance and speed. To figure out how long it would take Frank to finish the 60-mile bike race, we use the formula Time = Distance / Speed. Given that Frank averages a speed of 19 miles an hour, we divide the total distance (60 miles) by his average speed (19 mph).
So, 60/19 ≈ 3.16. That means Frank will take approximately 3.16 hour to complete the bike race.

Nancy's spaghetti and meatballs recipe calls for 2 cloves of garlic the recipe makes 8 servings how much garlic is in each serving
Answer:
1/4 clove
Step-by-step explanation:
Each serving of Nancy's spaghetti and meatballs recipe contains a quarter (or 0.25) of a garlic clove.
Explanation:In the given scenario, Nancy's spaghetti and meatballs recipe asks for 2 cloves of garlic and yields 8 servings. Hence, to find out the amount of garlic in each serving, we need to divide the total cloves of garlic by the number of servings. Hence,
Garlic per serving = Total garlic / Number of servings
Here's how to do the math:
Garlic per serving = 2 cloves / 8 servings = 0.25 cloves per serving
So, there is 0.25 or a quarter of a garlic clove in each serving of Nancy's spaghetti and meatballs recipe.

An observer at the top of a skyscraper sees a car on the road below. The angle of depression to the car is 29°. If the car is about 62 m from the skyscraper when it is seen, how tall is the skyscraper?
The height of the skyscraper is 34.4m
Step-by-step explanation:
Let the height of the skyscraper be 'h'
Distance between the skyscraper and the car = 62 m
Angle of depression = 29°
Angle = 61°
tan 61° = 62/h
1.80 = 62/h
h = 62/1.80
h = 34.4m
The height of the skyscraper is 34.4m

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain.
Answer:
So when two lines intersect, it creates 4 angles. The angles that lie opposite to each other are congruent
If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

The height of a trapezoid is 6 in. and it’s area is 72 in to the 2nd power. One base of the trapezoid is 6 inches longer than the other base. What are the lengths of the bases? Complete the explanation of how you found your answer.
One base is __ inches for one of the bases and __ inches for the other base.
Use the formula for the area of a trapezoid. Substitute 72 for A and 6 for h and simplify the equation to find __ = (b1 + b2). Use guess and check to find two numbers that add to __ with one number 6 more than the other to get __ inches for one of the bases and __ inches for the other base.
Given:
The height of the given trapezoid = 6 in
The area of the trapezoid = 72 in²
Also given, one base of the trapezoid is 6 inches longer than the other base
To find the lengths of the bases.
Formula
The area of the trapezoid is
[tex]A=\frac{1}{2} (b_{1} +b_{2} )h[/tex]
where, h be the height of the trapezoid
[tex]b_{1}[/tex] be the shorter base
[tex]b_{2}[/tex] be the longer base
As per the given problem,
[tex]b_{2}=b_{1} +6[/tex]
Now,
Putting, A=72, [tex]b_{2}=b_{1}+6[/tex] and h=6 we get,
[tex]\frac{1}{2} (b_{1} +b_{1}+6)(6) = 72[/tex]
or, [tex]b_{1}+b_{1}+6 = \frac{(72)(2)}{6}[/tex]
or, [tex]2b_{1}+6 = 24[/tex]
or, [tex]2b_{1}=24-6[/tex]
or, [tex]b_{1}= \frac{18}{2}[/tex]
or, [tex]b_{1}=9[/tex]
So,
The shorter base is 9 in and the other base is = (6+9) = 15 in
Hence,
One base is 9 inches for one of the bases and 15 inches for the other base.

pi/5
(3pi)/2
(2pi)/5
pi/2
Answer:
(2pi)/5
Step-by-step explanation:
The cosine function cos(x) has a period of 2*pi.
If we change the argument of the cosine, the new argument will have a period of 2*pi. If the new argument is 5x, we have that the period will be:
5x = 2*pi
x = 2*pi/5
The period of this function will be (2pi)/5, because for every (2pi)/5 change in the value of x, the function will have the same value. The value of 5 multiplying the cosine does not interfere in the period.
