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

The scale factor from triangles ABC to XYZ IS 6.

Option A is the correct answer.

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.

Answer:

c+b=1000

Step-by-step explanation:

This problem can be solved by process of elimination. If the end weight is 1000, then at the equal sign, it should also be 1000. Since the last option is the only one with 1000, then it would be the only correct option.

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

Given that the poster's length:

[tex]8\frac{1}{2}=\frac{17}{2}=8.5[/tex] inch

Thus, 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

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

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

Answer:

Therefore, point B is closer to the x-axis.

Please check the attached graph.

Step-by-step explanation:

We know that:

Given the points

Let us say

FOR POINT A(0, 7)

We 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)

We 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

Therefore, point B is closer to the x-axis.
