In ∆MNP, m∠N = 90º, NH – altitude, m∠P = 21º, PM = 4 cm. Find MH.

Sveta_85 [38]

Answer:

0.51 cm

Step-by-step explanation:

In right triangle MNP, MP = 4 cm, m∠N = 90°, m∠P = 21°

By the sine definition,

$\sin \angle P=\dfrac{\text{Opposite leg}}{\text{Hypotenuse}}=\dfrac{MN}{MP}\\ \\MN=MP\sin \angle P\\ \\MN=4\sin 21^{\circ}\approx 1.43\ cm$

Now, consider right triangle HMN (it is right because NH is an altitude). By the cosine definition,

$\cos \angle M=\dfrac{\text{Adjacent leg}}{\text{Hypotenuse}}=\dfrac{MH}{MN}\\ \\MH=MN\cos \angle M$

In the right triangle, two acute angles are always complementary, so

$m\angle M=90^{\circ}-m\angle P=90^{\circ}-21^{\circ}=69^{\circ}$

Thus,

$MH=1.43\cos 69^{\circ}\approx 0.51\ cm$

1200$ invested at a rate of 3.5% compounded quarterly; 4 years

Tju [1.3M]

Step-by-step explanation:

1st year:

(1200 x 3.5 x 1) ÷ 100 = $42

2nd year:

(1242 x 3.5 x 1) ÷ 100= $43.47

3rd year:

(1285.47 x 3.5 x 1) ÷ 100= $44.99≈ $45

4th year:

(1330.47 x 3.5 x 1) ÷ 100= $46.56

Compound interest:

$(42 + 43.47 + 45 + 46.56)

=$ 177.03

The following table shows the number of innings pitched by each of the Greenbury Goblins' starting pitchers during the Rockbotto

Lady_Fox [76]

Answer:

The number of innings Brantley pitched is 7.

Step-by-step explanation:

We are given that the table shows the number of innings pitched by each of the Greenbury Goblins' starting pitchers during the Rockbottom Tournament below;

Pitcher Number of innings pitched

Calvin 11

Thom 12

Shawn 7

Kris 3

Brantley x

Let the number of innings Brantley pitched be 'x'.

The mean of the following data set is given by the following formula;

Mean = $\frac{\text{Sum of all data values}}{\text{Total number of observations}}$

$8 = \frac{11+12+7+3+x}{5}$

$8\times 5 =33+x$

$40 = 33+x$

x = 40 - 33 = 7

Hence, the number of innings Brantley pitched is 7.
