Answer:

The area of the shaded region is 42.46 cm2

Step-by-step explanation:

Answer:

5 x 5 = 25

25 x 3.14 = 78.5

11 x11 = 121 - 78.5 = 42.5

42.5 cm

Step-by-step explanation:

The radius of the circle is 10.5.

Pythagorean theorem states that for a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We can apply this theorem only in a right triangle.

Example:

The hypotenuse side of a triangle with the two sides as 4 cm and 3 cm.

Hypotenuse side = √(4² + 3²) = √(16 + 9) = √25 = 5 cm

We have,

AC = 20 and BC = 17

From the figure,

We apply the Pythagorean theorem.

So,

AC² = BC² + AB²

Substituting,

20² = 17² + AB²

AB² = 400 - 289

AB² = 111

Now,

Radius = AB

So,

AB = √111

AB = 10.535

Rounding to the nearest tenth.

AB = 10.5

Thus,

The radius of the circle is 10.5.

Answer:

Total area= 207 ft^2

Step-by-step explanation:

You can divide the figure to make 2 big rectangles.

The first has a base of 15 ft and a height of 15 ft

A1 = b * h

A1= 15 ft * 9 ft        A1= 135 ft^2

The second has a base of 12 ft and a height of 6 ft

A2= b*h

A2= 12 ft * 6 ft

A2= 72 ft^2

Total area= A1+A2= 135 ft^2 + 72 ft^2  

Total area= 207 ft^2

  10. Expanded vertically by 3, shifted left 2 and up 4.

  11. Shifted right 6 and up 7.

Step-by-step explanation:

This sort of question involves matching patterns. You need to know what the various transformations look like, and what that means for a specific parent function.

Here are the transformations used in this problem:

For these problems, the parent function is f(x) = 1/x.

__

10. The multiplier of 3 in the numerator (3/x) means the function has been scaled vertically (expanded) by a factor of 3.

The replacement of x with x+2 means the function has been shifted to the right by -2 units. That is the same as shifted left 2 units.

The addition of 4 to the function value means the function has been shifted up by 4 units.

__

11. We note the numerator is still 1, so there is no vertical expansion. The replacement of x with x-6 means a right shift by 6 units. The addition of 7 to the function value means a shift up by 7 units.

Answer:

<1 = 95

<2 =85

Step-by-step explanation:

<1 = 95

They are alternate exterior angles and alternate exterior angles are equal when the lines are parallel

<1 + <2 = 180  since they form a straight line

95+ <2 =190

Subtract 95 from each side

95-95+<2 =180-95

<2 =85

Answer:

Step-by-step explanation:

The rate of growth (the slope of the transformed curve) is first higher than for an exponential function, but later it goes down. ... Initially, the quadratic function grows much faster. The function x² grows from 0 to 1 in finite time, while the exponential function takes from minus infinity to 0.

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  4a+5

Pull out from each group separately :

Group 1:   (4a+5) • (1)

Group 2:   (a-5) • (a2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  1  and the Trailing Constant is  5.

Answer:

S = {-1, 0, 1}

Step-by-step explanation:

First we need to solve the inequation x^2<=3

Using square root in both sides, we have:

|x| <= 1.73

Separating the module in two, we have:

x <= 1.73

x >= 1.73

So we have that -1.73 <= x <= 1.73

Solving this inequation only with integer values, we have:

x = -1, x = 0 or x = 1

So the set of integer solutions is S = {-1, 0, 1}

Answer:

Lin should expect to sell 10 cups more

Step-by-step explanation:

The line c = 2t − 89 relates the cups Lin expect to sale (c) with the high temperature of the day (t)

If high temperature on Saturday is t1, then high temperature on Sunday is (t1+5)

Cups sold on Saturday are: 2t1 − 89

Cups sold on Sunday are:  2(t1+5) − 89 = 2t1 + 10 - 89

Cups sold on Sunday - Cups sold on Saturday:

2t1 + 10 - 89 - (2t1 − 89) = 2t1 + 10 - 89 - 2t1 + 89 = 10

Answer:

-26

Step-by-step explanation:

If the temperature dropped by 14 degrees than it decreased by 14, which means we subtract:

-12-14= -26

Answer:

Each side is (7/2d +4) cm

Step-by-step explanation:

The perimeter of a square is given by

P = 4s  where s is the side length

14d +28 = 4s

Divide each side by 4

14d/4 +28/4 = 4s/4

7/2d +7 = s

Each side is (7/2d +4) cm

Answer:

6

Step-by-step explanation:

The slope (m) can be found using the formula ...

 m = (y2 -y1)/(x2 -x1)

Any pair of points will do. We can use the first two.

 m = (2 -(-10))/(17 -15) = 12/2

 m = 6
