Mathematics
1 answer:
snow_tiger [21]3 years ago

Answer:

QR ≈ 16.3

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{MN}{QR} = \frac{MP}{QT} , substitute values

\frac{40.3}{QR} = \frac{57}{23} ( cross- multiply )

57 QR = 926.9 ( divide both sides by 57 )

QR ≈ 16.3 ( to the nearest tenth )

I need serious help with this equation.​
garri49 [273]

Answer:

First, it’s already telling you that you need to find d, which is the opposite of degree 59. This means you have to do the exact thing for degree 37. Since it’s already telling you to use sine, you need to look at the opposite side of 37 which is 98.4.

So ? is 98.4

Now, you need to find sin 59 / d.

First, plug in sin 98.4 sin (37) in your calculator (make sure it’s in degree setting)

The result is 59.2.

Now, 59.2 = sin 59 / d.

Switch sides like this: d = 59.2 sin (37)

And the answer is approximatley d = 35.6

? = 98.4

d = 35.6

F(x)=-3/4x+9 what are the steps for finding f^-1(x)
ozzi

The inverse function f^{-1}(x) is such that

f\left(f^{-1}(x)\right) = x

If f(x)=-\frac34x+9, then we have

f\left(f^{-1}(x)\right) = -\dfrac34f^{-1}(x)+9 = x

Solve for the inverse :

-\dfrac34f^{-1}(x)+9 = x \\\\ -\dfrac34f^{-1}(x) = x-9 \\\\ f^{-1}(x) = -\dfrac43(x-9) \\\\ \boxed{f^{-1}(x) = -\dfrac43x+12}

May someone answer this plzz
Nataly_w [17]

D)

6 5/8

or 6.625

Basically

1/8*3 =0.375

1/4 * 3 =0.75

1/2*5 =2.5

and 3/4*4=3

So then,

0.375+0.75+2.5+3=6.625 or 6 5/8 in fraction!
