What is the slope of a line perpendicular to the line whose equation is
10x – 8y = -80. Fully reduce your answer.
Answer:
-4/5
Step-by-step explanation:
write the given equation in y=mx+b form, where m is the slope
10x-8y=-80
-8y= -10x-80 divide both sides by -8
y=(10/8)x+10
y=(5/4)x+10
m= 5/4 is the slope of the given function
the slope of an equation that is perpendicular is the negative reciprocal of the given one so is
m= -4/5

Merritt is driving to Mount Shasta. On her map, she is a distance of 7 inches away. The scale of the map is 2 inches is to 50 miles. How far must Merritt travel to reach her destination?
Answer:
7 inches on the map is 175 miles.
Step-by-step explanation:
2 inches equals 50 miles. Use 50 divided by 2 to find the 1-inch scale which is 1:25 ( one inch to 25 miles)
Find a formula for the function f(x) such that f′(x)=sin(x) and f(2)=5.
Answer: f(x) = -cos(x) + 4.584
Step-by-step explanation:
we know that f'(x) = sin(x)
if we integrate that, we get:
f(x) = -cos(x) + C
Where C is a constant of integration.
And we also want that:
f(2) = 5
with that relationship we can find the value of C.
f(2) = 5 = -cos(2) + C
(The calculation is done in radians)
5 = -(-0.416) + C
5 - 0.416 = C = 4.584
Then the function is:
f(x) = -cos(x) + 4.584

which point is closer to the x-axis (0.7, 21) or (0.77, 10)
Answer:
As
[tex]d_A=21[/tex][tex]d_B=10[/tex]Therefore, point B is closer to the x-axis.
Please check the attached graph.
Step-by-step explanation:
We know that:
x-coordinate of any point P(x, y) gives its distance of that point from the y-axisy-coordinate of any point P(x, y) gives its distance of that point from the x-axisGiven the points
(0.7, 21)(0.77, 10)Let us say
A(0.7, 21)B(0.77, 10)FOR POINT A(0, 7)
As the y-coordinate of point A(0.7, 21) ⇒ y = 21We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis
Thus, the distance of point A(0.7, 21) from the y-axis is 21 units.
i.e.
[tex]d_A=21[/tex]
FOR POINT B(0.77, 10)
As the y-coordinate of point A(0.77, 10) ⇒ y = 10We know that the y-coordinate of any point P(x, y) gives its distance of that point from the x-axis
Thus, the distance of point B(0, 7) from the y-axis is 10 units.
i.e.
[tex]d_B=10[/tex]
As
[tex]d_A=21[/tex][tex]d_B=10[/tex]Therefore, point B is closer to the x-axis.
Please check the attached graph.

A poster of the detroit lions football players uses a scale of 4 inches= 3 feet. If quarterback Matthew stafford is 8 1/2 inches tall on the poster, find his actual height.
Answer:
The actual height = 6.38 feet
Step-by-step explanation:
Given that a poster of the detroit lions football players uses a scale
of 4 inches = 3 feet
so
1 inch = 3/4 feetGiven that the poster's length:
[tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex] inch
We need to determine the actual height if quarterback Matthew Stafford is 8 1/2 inches tall on the poster.As 1 inch = 3/4 feetThus, we need to multiply 8.5 inches by 3/4 to determine the actual height of the player.
Actual height = 8.5 × 3/4 feet
= 6.38 feet
Therefore, the actual height = 6.38 feet

find the missing measures
Answer:
8 cm and 28 cm
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
(i)
Here A = 48, b = AB and h = DE = 6 , then
AB × 6 = 48 ( divide both sides by 6 )
AB = 8 cm
(ii)
Here A = 252, b = PQ = 9 and h = RT , then
9 × RT = 252 ( divide both sides by 9 )
RT = 28 cm

The scale factor from triangles ABC to XYZ IS 6.
Option A is the correct answer.
What is a scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object,
We have,
ΔABC and ΔXYZ
The corresponding sides are:
AB = XY
BC = YZ
AC = XZ
Now,
We see that,
XY = 6 x AB
YZ = 6 x BC
XZ = 6 x AC
So,
The scale factor is 6.
Thus,
The scale factor from triangles ABC to XYZ IS 6.
