Answer:

Please see the solution below:

Step-by-step explanation:

33)

Principal = $5,000

Interest Rate = 2.5% = 0.025

Time = 10 years

Interest = Principal x Interest Rate x Time

Interest = $5,000 x 0.025 x 10

Interest = $1,250

Total Balance = Interest + Principal

Total Balance = $1,250 + $5,000

Total Balance = $6,250

34)

Principal = $45,000

Interest Rate = 4.5% = 0.045

Time = 20 years

Interest = Principal x Interest Rate x Time

Interest = $45,000 x 0.045 x 20

Interest = $40,500

Please help me i need to find the area of shaded region please help me

Montano1993 [528]

Answer:

Part 1) $A=60\ ft^2$

Part 2) $A=80\ cm^2$

Part 3) $A=96\ m^2$

Part 4) $A=144\ cm^2$

Part 5) $A=13\ m^2$

Part 6) $A=(49\pi -33)\ in^2$

Step-by-step explanation:

Part 1) we know that

The shaded region is equal to the area of the complete rectangle minus the area of the interior rectangle

The area of rectangle is equal to

$A=bh$

where

b is the base of rectangle

h is the height of rectangle

$A=(12)(7)-(8)(3)\\A=84-24\\A=60\ ft^2$

Part 2) we know that

The shaded region is equal to the area of the complete rectangle minus the area of the interior square

The area of square is equal to

$A=b^2$

where

b is the length side of the square

$A=(12)(8)-(4^2)\\A=96-16\\A=80\ cm^2$

Part 3) we know that

The area of the shaded region is equal to the area of four rectangles plus the area of one square

$A=4(4)(5)+(4^2)\\A=80+16\\A=96\ m^2$

Part 4) we know that

The shaded region is equal to the area of the complete square minus the area of the interior square

$A=(15^2)-(9^2)\\A=225-81\\A=144\ cm^2$

Part 5) we know that

The area of the shaded region is equal to the area of triangle minus the area of rectangle

The area of triangle is equal to

$A=\frac{1}{2}(b)(h)$

where

b is the base of triangle

h is the height of triangle

$A=\frac{1}{2}(6)(7)-(4)(2)\\A=21-8\\A=13\ m^2$

Part 6) we know that

The area of the shaded region is equal to the area of the circle minus the area of rectangle

The area of the circle is equal to

$A=\pi r^{2}$

where

r is the radius of the circle

$A=\pi (7^2)-(3)(11)\\A=(49\pi -33)\ in^2$

How to get a equation of a line in slope intercept form with the rate of change as undefined?

harkovskaia [24]

Answer:

Linear equation: x = -1

Step-by-step explanation:

Vertical lines have undefined slopes, as represented by the linear equation, <em>x = a, </em>where the x-intercept is (a, 0).

A vertical line has <em>undefined</em> slope because all points the line have the same x-coordinate. Since any two points on a vertical line have the same x-coordinate, slope cannot be computed as a finite number. The equation cannot be expressed in slope-intercept form because it has an undefined slope.

Therefore, since you're given the point, (-1, 4), then it means that your equation will be: x = -1.
