Which expressions are equivalent to 5p+3p+(-9)5p+3p+(−9)5, p, plus, 3, p, plus, (, minus, 9, )? Choose all answers that apply:

Lemur [1.5K]

Answer:

Option B.

Step-by-step explanation:

The given expression is

$5p+3p+(-9)$

We need to find an expression which is equivalent to the given expression.

Combine like terms.

$(5p+3p)-9$

$8p-9$

The simplified form of given expression is 8p-9. So, option A is incorrect.

In option B, the given expression

$3(p+(-3))+5p$

$3(p-3)+5p$

Using distributive property, we get

$3p-9+5p$

Combined liker terms.

$(5p+3p)-9$

$8p-9$

It is same as the simplified form of given expression.

Therefore, the expression 3(p+(-3))+5p is equivalent to the given expression and correct option is B.

Find the cos A and tan B to four decimal places. URGENT

Nikolay [14]

cos A is 0.8511 and tan B is 1.6

Step-by-step explanation:

Find the 3rd length or the hypotenuse.

<u>Pythagoras theorem</u>

$hypotenuse^{2}$ = $adjacent^{2}$ + $opposite^{2}$

$hypotenuse^{2}$ = $8^{2}$ + $5^{2}$

$hypotenuse^{2}$ = 64 + 25

hypotenuse = $\sqrt{89}$

hypotenuse = 9.4

a) Cos A

<u>Data:</u>

Adjacent = 8

Hypotenuse = 9.4

<u>Formula:</u>

Cos (Angle) = $\frac{adjacent}{hypotenuse}$

Cos A = $\frac{8}{9.4}$

Cos A = 0.8511

A = $cos^{-1}$ (0.8511)

A = 31.7°

b) Tan B

<u>Data: </u>

Opposite = 8

Adjacent = 5

<u>Formula:</u>

Tan (Angle) = $\frac{opposite}{adjacent}$

Tan B = $\frac{8}{5}$

Tan B = 1.6

B = $cos^{-1}$ (1.6)

B = 58°

Therefore, cos A is 0.8511 and tan B is 1.6.
