A model car has a scale factor of 1/64 The diameter of a tire on the model is 0.39 inches. So, the diameter of the tire on an ac
Blizzard [7]
This is the concept of scale factors, given that the length of the model which has been modeled by scale factor 1/64 is 0.39 inches, then the actual diameter will be:
scale scale factor=(model diameter)/(actual diameter)
where:
actual diameter=(model diameter)/(scale factor)
=0.39/(1/64)
=24.96 inches

Graph h(x)=7 sin x ?
DENIUS [597]

Answer:

The graph of h(x) is shown below.

Step-by-step explanation:

The given function is

h(x)=7\sin x

The general form of sine function is

f(x)=a\sin(bx+c)+d

Where, a is amplitude, b is period, c is phase shift and d is vertical shift.

So, the amplitude of the given function is 7, period is 1, phase shift is 0 and vertical shift is 0.

It means the minimum value of function is -7 and maximum value is 7.

Put x=0 in the given function.

h(x)=7\sin (0)=7(0)=0

Put  x=-\frac{\pi}{2} in the given function.

h(x)=7\sin (-\frac{\pi}{2})=-7(1)=-7

Put  x=\frac{\pi}{2} in the given function.

h(x)=7\sin (\frac{\pi}{2})=7(1)=7

Therefore the points on the function are (0,0), (-\frac{\pi}{2},-7),(\frac{\pi}{2},7).

The graph of function is shown below.

Write an equation in slope intercept form for a line with a slope of - 3/2 that passes through the point 4,10 help please
Archy [21]

Answer:

y =  \frac{ - 3}{2} x + 16

Step-by-step explanation:

They give us the slope so this makes it a lot easier.

Slope intercept formula is

y=mx+b

(m) is slope

(b) is y intercept

we can apply our slope into the formula

y=-3/2x+b

Now we can replace (y) with the (y) from the ordered pair they gave us (4, 10), and replace the (x) with the (x) from the ordered pair they gave us

(4, 10)

10=-3/2(4)+b

Now solve

10=-6+b

Add 6 to each side

16=b

Now we we put both our slope and intercept into the formula.

y =  \frac{ - 3}{2} x + 16

Mazyrski [523]

Answer:

elimination.

Step-by-step explanation:

6x-6x eliminates and then you just have to simplify the expression. then plug whatever you got for y into one of the expressions and then you have an answer.
