Mathematics
1 answer:
Rainbow [258]3 years ago
8 0

Answer:

7.5 cm²

Step-by-step explanation:

Area of shaded sector = θ/360 × πr²

Where,

θ = 180° - 84° = 96°

r = ½(6) = 3 cm

Area of shaded sector = 96/360 × π × 3²

Area = 7.53982238 ≈ 7.5 cm²

Mei Mei invested $1700 in an account that pays 3% interest compounded annually.
algol [13]

Answer:

$2728

Step-by-step explanation:

Use compound interest formula:

A = P(1 + \frac{r}{n})^{nt}

P = 1700, r = 0.03, n = 1, t = 16

Plug in numbers:

A = 1700(1 + \frac{0.03}{1})^{(1)(16)}

Simplify:

A = 1700(1.3)^{16

Use calculator:

A = 2728

Find an equation of the line through the given point and perpendicular to the given line
s344n2d4d5 [400]

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

For two lines to be perpendicular, the slope of one line is the negative reciprocal of the other line. The equation of the given line is

y = 2x - 2

Comparing with the slope intercept form,

Slope, m = 2

This means that the slope of the line that is perpendicular to it is -1/2

The given points are (-3, 5)

To determine c,

We will substitute m = -1/2, y = 5 and x = - 3 into the equation, y = mx + c

It becomes

5 = -1/2 × - 3 + c

5 = - 3/2 + c

c = 5 + 3/2

c = 13/2

The equation becomes

y = -x/2 + 13/2
