Answer:

All you need to remember is the rules

Step-by-step explanation:

Let us remember

a to the m power x a to the nth power is = a to the m+n power. (add the exponents)

And

a to the m power ÷ a to the nth power is = a to the m-n power. (subtract the exponents) So

14 to the -4 power x 14 to the 7 power= 14 to the -4+7 which is equal to 14 to the 3rd power

Translate the phrase into an algebraic expression.

adell [148]

Answer:

8 + $\frac{5}{w}$

Step-by-step explanation:

From the phrase, the answer is smaller(less) by 8 when compared(equal (=)) to quotient of 5 and w ...

So:

Answer - 8 = quotient of 5 and w

Here, quotient is the whole number from a division. The division here is $\frac{5}{w}$

Therefore,

Answer - 8 = $\frac{5}{w}$

Answer = 8 + $\frac{5}{w}$

Hence the phrase into algebraic expression is 8 + $\frac{5}{w}$

Find the approximate value of each trigonometric function.

vodka [1.7K]

Answer:

Given

tanθ = 3.454
θ is in the III quadrant

We know in the III quadrant both sine and cosine are negative.

Use the following identities to get values of sinθ and cos θ

sinθ = - tanθ/√(1 +tan²θ)
cosθ = - 1/√(1 +tan²θ)

Substitute the value of tanθ and find sine and cosine:

sinθ = - 3.454/√(1 + 3.454²) = - 0.961
cosθ = - 1/√(1 + 3.454²) = - 0.278

A rectangular prism and its dimensions are shown in the diagram.

lilavasa [31]

Answer:

51.08 in.²

Step-by-step explanation:

S.A = (l x b) + (l × h) + (b × h)

= (8.2 in. × 3.4 in.) + (8.2 in. × 2 in.) + (3.4 in. × 2 in.)

= 27.88 in.² + 16.4 in.² + 6.8 in.²

= 51.08 in.²

If a varies directly as the cube root of b and if a=3 and b=64.find the formula connecting the variables hence find b when a=15/

Liono4ka [1.6K]

Answer:

b = 125

Step-by-step explanation:

Given a varies directly as $\sqrt[3]{b}$ then the equation relating them is

a = k $\sqrt[3]{b}$ ← k is the constant of variation

To find k use the condition a = 3 , b = 64 , then

3 = k $\sqrt[3]{64}$ = 4k ( divide both sides by 4 )

$\frac{3}{4}$ = k

a = $\frac{3}{4}$ $\sqrt[3]{b}$ ← equation of variation

When a = $\frac{15}{4}$ , then

$\frac{15}{4}$ = $\frac{3}{4}$ $\sqrt[3]{b}$ ( multiply both sides by 4 to clear the fractions )

15 = 3 $\sqrt[3]{b}$ ( divide both sides by 3 )

5 = $\sqrt[3]{b}$ , then

b = 5³ = 125
