Answer: See below

Step-by-step explanation:

1) 1/2 x 3.14 x 35^2

1/2 x 3.14 x 1225

1/2 x 3846.5

A = 1923.25 yd^2

2) (3.14)r^2

(3.14) (35)^2

3846.50 yd^2

3) P = d + (3.14)r^2

P = 70 + (3.14) (35)

P = 70 + 109.90

P = 179.90 yd

4) P = 2( l + w)

P = 2 (70 + 100)

P = 2 (170)

P = 340

Perimeter of the square minus the perimeter of the circle.

340 - 179.90 = 160.10 yd

Answer:

y=[-4]x+[10]

Step-by-step explanation:

For a line to be perpendicular to another it must have the reverse reciprocal of the opposite line, to find the reverse reciprocal you take your slope, flip the numerator and denominator, and multiply it by -1.

The slope \frac{1}{4} turns into \frac{4}{1} and is then multiplied by -1 to become \frac{-4}{1} which can be simplified down to: -4

Now that we know the slope we need the line to pass through a point, so we will use point slope form:

y-y1=m(x-x1)
Substitute in our slope and point values:

y-2=-4(x-2)

Now solve for y:

y-2=-4(x-2)\\y-2=-4x+8\\y=-4x+10

Then you will find that line y=-4x+10 runs perpendicular to y=\frac{1}{4}x-8 and intersects point (2,2).

A rectangle has a height of k2 + 3 and a width of k2 + 7.
ElenaW [278]

Answer:

The area of the rectangle in polynomial form is k^4 +10 k^2 + 21

Step-by-step explanation:

Given

Shape: Rectangle

Height: k^2 + 3

Width: k^2 + 7

Required

Area of the rectangle

The area of a rectangle is calculated as thus;

Area = Length * Width

By substituting k^2 + 3 for height and k^2 + 7 for width; This gives

Area = (k^2 + 3)(k^2 + 7)

Expand the bracket

Area = k^2(k^2 + 7) + 3(k^2 + 7)

Open each bracket

Area = k^2*k^2 + k^2*7 + 3*k^2 + 3*7

Area = k^4 +7 k^2 + 3k^2 + 21

Area = k^4 +10 k^2 + 21

Hence, the area of the rectangle in polynomial form is k^4 +10 k^2 + 21

Find the exact value of tan 195 degrees
melamori03 [73]

Answer:

tan(195\°)=tan(15\°)=0.267949192431123...

Step-by-step explanation:

We know that

tan(195\°)=tan(15\°), because 195\° - 180\° = 15\°.

Now, angle 15° or 195° is not an important angle which can be solve by a given table like 30°, 45° or 60°. This means we have to use the calculator to find the more exact value, which is

tan(195\°)=tan(15\°)=0.267949192431123...
