Vika [28.1K]3 years ago
7 0

Answer:

3/4

Step-by-step explanation:

f(x)=3•2^x

Let x = -2

f(-2)=3•2^-2

Exponents first  ( We know a^-b = 1/ a^b)

f(-2)=3• 1/2^2

     =3 * 1/4

     = 3/4

Wewaii [24]

Answer:

$20,850.00)

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Solving our equation:

A = 139000(1 + (0.05 × 3)) = 159850

A = $159,850.00

The total amount accrued, principal plus interest, from simple interest on a principal of $139,000.00 at a rate of 5% per year for 3 years is $159,850.00.

If M is the midpoint of segment AB and AM=9x-5 and MB=15-x, what is the length of AB?
kkurt [141]

Answer:

<h2>AB = 8x+10</h2>

Step-by-step explanation:

If M is the midpoint of the segment AB, then <em>AM+MB = AB</em>. Given the following parameters;

AM=9x-5 and MB=15-x

Required parameter

segemnt AB

Substituting the given parameters into the given formula to get AB we will have;

AB = AM+MB

AB = 9x-5+15-x

collect like terms

AB = 9x-x-5+15

AB = 8x+10

<em>Hence the length of segment AB is 8x+10</em>

Find the exact or approximate area of the shaded region
Lana71 [14]

Answer: 18.24 cm^2

Step-by-step explanation:

the two 135 degree angles indicate that the third angle (the one with the shaded region) is 90 degrees, which means that the shaded region is within 1/4 of the circle.

1. In order to find the area for that 1/4 region, you would have to find the area of the circle and divide it by 12

[r^2(3.14)]/4      pi is substituted by 3.14, and the radius is 8.

50.24 is the area of 1/4 of the circle.

2. Next you'd have to find the area of the triangle formed by the shaded region, and subtract the triangle from the area of the 1/4 circle.

the triangle is an isoceles triangle with two sides each valuing at 8cm, so to find the area of the triangle you would multiply the two sides (or square them since they're the same number) and divide by two

this means the triangle is 32 cm^2

3. we can subtract the 1/4 circle (50.24) by the area of the triangle (32) to get the area of the shaded region, which is <u>18.24 cm^2</u>
