Answer:

26

Step-by-step explanation:

cosθ = adjacent / hypotenuse

cos(26) = 18 / x

x= 18 / cos(26)

x= 27.82418 ≈ 20 (to nearest tenth)

Answer:

x ≈ 20

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos26° = \frac{adjacent}{hypotenuse} = \frac{18}{x} ( multiply both sides by x )

x × cos26° = 18 ( divide both sides by cos26° )

x = \frac{18}{cos26} ≈ 20.0 ( to the nearest tenth )

Show the steps and name the properties you used to solve the equation below
DochEvi [55]

Answer:

0.477121=−log(3x+7)+0.30103

Step 1: Flip the equation.

−log(3x+7)+0.30103=0.477121

Step 2: Add -0.30103 to both sides.

−log(3x+7)+0.30103+−0.30103=0.477121+−0.30103

−log(3x+7)=0.176091

Step 3: Divide both sides by -1.

log(3x+7)=−0.176091

Step 4: Solve Logarithm.

log(3x+7)=−0.176091

10log(3x+7)=10−0.176091

3x+7=0.666667

3x+7−7=0.666667−7(Subtract 7 from both sides)

3x=−6.333333

3x

3

=

−6.333333

3

(Divide both sides by 3)

x=−2.111111

Find the product. Write your answer in<br> exponential form.<br> 5^7•5^-9•5^-5
MissTica

5^7 = 5 × 5 × 5 × 5 × 5 × 5 × 5 = 78,125

5^-9 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.000000512

5^-5 = 5 ÷ 5 ÷ 5 ÷ 5 ÷ 5 = 0.00032

78,125 × 0.000000512 × 0.00032 = 0.0000128‬

Answer: 0.0000128‬ or 1.28 x 10^-5
