F(x) = 3x + 5<br> Work out a if f(a)= -13
vekshin1

Answer:

a = - 6

Step-by-step explanation:

Given

f(x) = 3x + 5 , then

f(a) = 3a + 5 and f(a) = - 13 , then equating the right sides

3a + 5 = - 13 ( subtract 5 from both sides )

3a = - 18 ( divide both sides by 3 )

a = - 6

fenix001 [56]

Answer:

21 7/8 square feet

Step-by-step explanation:

To solve the above Question, we have to used the formula of a parallelogram

The formula is given as:

Base × Height

Base = 6 1/4 feet

Height = 3 1/2 feet

Area = 6 1/4 × 3 1/2

Area = 25/4 × 7/2

Area = 175/8

Area = 21 7/8 ft²

Therefore, they would need 21 7/8 square feet poster paper for the parallelogram shaped banner

A central angle θ in a circle of radius 4 m is subtended by an arc of length 5 m. find the measure of θ in degrees. (round your
koban [17]

Answer:

\theta=71.6\°

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

C=2\pi r

we have

r=4\ m

substitute the values

C=2\pi (4)=8 \pi\ m

step 2

Remember that

360 degrees subtends the arc of length  8 \pi\ m (circumference)

so

by proportion

Find the measure of θ by an arc of length 5 m

assume \pi=3.1416

\frac{360}{8\pi}=\frac{\theta}{5}\\ \\ \theta=360*5/8\pi \\ \\ \theta=71.6\°
