Tina wants to save money for school. tina invests $400 in an account that pay an interest rate of 7.5%. How many years will it t

joja [24]

Here's the given:
P=$400
i=7.5%
A=$8500

The formula used for this problem is:
A = P(1+i)^t

Manipulating the equation to arrive at t, we have:
t = ln(A/P) / ln(1+i)

Plugging in values:
t = ln($8500/$400) / ln(1+0.075)
t = 42.26 years

What is the surface area of a cylinder that is 5 centimeters high and has a diameter of 1.5 centimeters?

olchik [2.2K]

The surface area of cylinder is 8.625 $\pi$ $cm^{2}$ , if the cylinder has 5 centimeters high and 1.5 cm of diameter.

Step-by-step explanation:

The given is,

Cylinder has a 5 centimeters height

Diameter of the cylinder is 1.5 centimeters

Step:1

Formula for the surface area of cylinder is,

$A=2\pi r h + 2\pi r^{2}$ ......................................(1)

Where,

h - Height of cylinder

r - Radius of cylinder

From the values of h and r,

$r=\frac{d}{2}$

= $\frac{1.5}{2}$

r = 0.75 cm

From the formula,

= ( 2 × $\pi$ × 0.75 × 5 ) + ( 2 × $\pi$ × $0.75^{2}$ )

= ( 7.5 $\pi$ ) + ( 1.125 $\pi$ )

A = 8.625 $\pi$ $cm^{2}$

Result:

The surface area of cylinder is 8.625 $\pi$ $cm^{2}$ , if the cylinder has 5 centimeters high and 1.5 cm of diameter.

The midpoint of AB is M(-2, 1). If the coordinates of A are (-3,-5),

mrs_skeptik [129]

Answer:

B= (-1, 7)

Step-by-step explanation:

Midpoint formula is X1 plus X2, then divided by 2. So, because the midpoint is given you work backwards. So for the x value do (-3 + x) divided by 2 equals -2 and solve for x and you do the same thing for the Y value
