Answer:

3.44.

Step-by-step explanation:

We can see that in this square, the radii of the semicircles are 2. Using that, we can calculate that the area of each one is 6.58. Both combined is 12.56. Now, the original area of the circle was 16. 16 minus 12.56 is equal to 3.44, so the area of the shaded region is 3.44.

3.44

Answer:

D

Step-by-step explanation:

It is a 30, 60, 90 triangle

if the leg on the same side as the 90 degree angle is [tex]14\sqrt{3}[/tex], then:

The base is 14, and the hypotenuse is 28

In this type of triangle:

the base [tex]\sqrt{3}[/tex] is the other leg

and 2 times the base is the hypotenuse

so x=14, and y=28

Answer D

Answer:

y= 16(0.25)^x

Step-by-step explanation:

y= 16(0.25)^x

The exponential equation represents an exponential decay because the rate of decay is 0.25 which is less than 1.

The general form equation is:

y(x)= a(1-r)^x such that r is the decay percent.

Comparing two equation we have 1-r = 0.25

==> r= 1-0.25 = 0.75 = 75%

2. y= 0.8(1.8)^x

The equation represents exponential growth because the growth factor is greater than 1.

==> 1+r = 1.8

==> r= 0.8 = 80%

3. y= 17(1/5)^x

The equation represents exponential decay because 1/5 is less than 1.

==> 1-r = 1/5

==> r= 1- 1/5 = 4/5 = 0.8= 80%

Answer:

8*8+12*3=100 is the answer

Given:

The equation is:

[tex]x^2-10x=7[/tex]

To find:

The number that should be added to sides of the equation to complete the square.

Solution:

If an expression is in the form of [tex]x^2+bx[/tex], then we have to add [tex]\left(\dfrac{b}{2}\right)^2[/tex] to make it perfect square.

We have,

[tex]x^2-10x=7[/tex]             ...(i)

To make it perfect square we need to add square of half of coefficient of x on both sides.

Coefficient of x is -10, so square of half of coefficient of x is:

[tex]\left(\dfrac{-10}{2}\right)^2=(-5)^2[/tex]

[tex]\left(\dfrac{-10}{2}\right)^2=25[/tex]

On adding 25 on both sides of (i), we get

[tex]x^2-10x+25=7+25[/tex]

[tex](x-5)^2=32[/tex]

Therefore, we need to add 25 to both sides of the equation to complete the square.

Given :

⊕   f(x) = 2x + 1

⊕   g(x) = 5x + 4

⊕   m(x) = f(x) - g(x)

⇒   m(x) = (2x + 1) - (5x + 4)

⇒   m(x) = 2x + 1 - 5x - 4

⇒   m(x) = -3x - 3

Step-by-step explanation:

To evaluate f(- 7) substitute x = - 7 into f(x)

f(- 7) = 2(- 7) + 2 = - 14 + 2 = - 12

Similarly for g(- 4)

g(- 4) = 3(- 4)³ + 5 = 3(- 64) + 5 = - 192 + 5 = - 187

x=y−4

Answer:

28%

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Percent of catalogues received = 100% - percent of magazines received

100 - 22 = 78%

Percent of clothing catalogues = 0.78 x 36 = 28%

Answer:

y = (-1 visit/block)x + 9 visits

6 visits

Step-by-step explanation:

The y-intercept is 9 (meaning 9 visits per week).

Note that (1, 8) is a point on the line.

To find the equation of this line, start with the slope-intercept form y = mx + b.  We know that when x = 1, y = 8 and that the y-intercept, b, is 9.  Therefore:

8 = m(1) + 9.

Solve this by subtracting 9 from both sides.  We get:

-1 = m

The slope is m = -1 visits/block

and the desired equation is y = (-1 visit/block)x + 9 visits

If a particular coffee shop is 3 blocks away, we predict that the number of visits per week made to this shop is y = -1(3) + 9, or 6 visits

Answer:

let kiran's age be x

kiran's father's age is 65

acc.to ques

kiran's father is 8 years older than 3 times kiran's age ....which gives us the equation as follows

8+3x =65

therefore

3x =65-8

3x =57

x =57/3

x= 19 ans

so kiran's age is 19 years.

Answer:

kiran is 19 years old.

Step-by-step explanation:

kiran's father age = 65

let kiran's age be x

kiran's father is 8 years older than three times kiran's age means 8 + 3x

so according to the question equation is

65 =  8 + 3x

65 - 8 = 3x

57/3 = x

19 = x

therefore kiran's age is 19 years.

-3 is the value of x in the solution set of inequality 2(3x-1)≥4x-6

The given inequality is 2(3x-1)≥4x-6

We have to find the solution set of the inequality.

Let us plug in x value as 10.

2(3(-10)-1)≥4(-10)-6

2(-30-1)≥-40-6

-62≥-46

It is not true so -10 is not the solution of given inequality.

Now plug in -5.

2(3(-5)-1)≥4(-5)-6

2(-16)≥-20-6

-32≥-26

It is not true so -5 is not the solution of given inequality.

Now plug in -3.

2(3(-3)-1)≥4(-3)-6

2(-10)≥-12-6

-20≥-18

It is not true so -3 is not the solution of given inequality.

Now plug in -1

2(-3-1)≥-4-6

-8≥-10

It is true

So -3 is the value of x in the solution set of inequality 2(3x-1)≥4x-6.
