Answer:

v=10.1

Step-by-step explanation:

v= 4.5 + at  -------> equation 1

given

a=1.6

t=3.5

so we will plug in the value in equation 1

v = 4.5 + (1.6 x 3.5)

v = 4.5 + 5.6

v = 10.1

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither
stiks02 [169]

Answer:

C)  Neither

Step-by-step explanation:

y = -1/4x + 8

-2x + 8y = 4

To compare the slopes  we need to convert the second equation to the same form as the first ( that is slope/intercept form).

-2x + 8y = 4

8y = 2x + 4

Divide through by 8:-

y = 1/4 x + 1/2

The slope of the first line is -1/4 and its  1/4 for the second line.

If the slopes were the same the lines would be parallel and if they were perpendicular  their product would be = -1.

The product is 1/4 * -1/4 = -1/16

So they are neither parallel nor perpendicular.

Suppose you invest $10,000 in a mutual fund that earns 6% annual interest. What is the value of your investment 30 years later?
likoan [24]

Answer:

$57400

Step-by-step explanation:

Given data

P= $10,000

R= 6%

T= 30 years

Let us Assume the investment is compounded Anually

A= P(1+r)^t

A=10000(1+0.06)^30

A=10000(1.06)^30

A=10000*5.74

A=$57400

Hence the Final Amount after 30 years compounded anually is $57400
