HELP PLEASE WORTH 23 points

Answer:

21.5 square units

Step-by-step explanation:

The 4 circles touching eachother have a total combined length of 20.

There are 4 circles. 20/4 = 5. The diameter of each circle is 5 units.

The length ofthe rectangle is 20 units. the width of the rectangle is 5 units.

The area of the shaded region is the area of the rectangle minus the ares of 4 circles.

A = area of rectangle - area of 4 circles

A = LW - 4 × πr²

The radius of each ciorcle is d/2 = 5/2 = 2.5

A = 20 × 5 - 4 × 3.14 × 2.5²

A = 100 - 78.5

A = 21.5

Answer:

for every 21 votes for A there were 6 for b or 9 for c

Answer:

f = 79

Step-by-step explanation:

You need to perform one-step equations process

146 + f = 225 (You're trying to solve for "f")

*First way, you could subtract both sides by 146 which makes the 146 cancel out then do 225-146 = 79. So f is 79

*A rule to remember is that the opposite of addition is subtraction. If you move 146 to 225 side you must switch it to negative 146.

Answer:

x = 98 degrees

Step-by-step explanation:

The sum of angles in a pentagon is 540 degrees. You can find this with the formula where n is the number of sides: 180(n-2). This formula will find the angle sum of a polygon. Now, since you know the value of every other angle except X, we can construct the equation 112+100+113+117+x=540

Solving this equation yields x=98 degrees

Sum of angles in a pentagon is 540°

x = 540 - (117+113+100+112)

x = 540 - 442

x = 98°

Using it's concept, it is found that there is a 0.643 = 64.3% probability that it will rain in the village on Wednesday.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, considering Monday - Tuesday - Wednesday, the possible outcomes are as follows:

R - R - R(0.7 x 0.7 x 0.7)

R - N - R(0.7 x 0.2 x 0.6)

N - R - R(0.3 x 0.6 x 0.8)

N - N - R(0.3 x 0.4 x 0.6)

Then, the probability is given by:

p = 0.7 x 0.7 x 0.7 + 0.7 x 0.2 x 0.6 + 0.3 x 0.6 x 0.8 + 0.3 x 0.4 x 0.6 = 0.643.

0.643 = 64.3% probability that it will rain in the village on Wednesday.

Answer:

Step-by-step explanation:

Givens

pi = 3.14

d = 10 cm

h = 2*d

Formula

The combined formula is given below.

SA = 2*pi*r^2  +  2*pi*r * h

Conversions

d = 10 cm

h = 2*10

h = 20 cm

r = d/2

r = 10 / 2

r = 5cm

Solution

SA = 2*pi*r^2  +  2*pi*r * h

SA = 2*3.14*5^2 + 2*3.14*5*20

SA = 157 + 628

SA = 785 cm^2

Answer:

[tex](x+4)^2+3=0[/tex]

Step-by-step explanation:

Hey there!

Standard form is what this equation is in

Standard form is this: [tex]ax^2+bx+c[/tex]

So order to complete the square, you need to take the [tex]b[/tex] term out of the equation, divide it by two, and then square it

In this case, the [tex]b[/tex] term is 8

We need to divide 8 by 2 ---> 4

Then square 4 ---> 16

So now you should add 16 to both sides

[tex]x^2+8x+16+19=16[/tex]

Now you can simplify the LHS

[tex](x+4)^2 +19=16[/tex]

Now you subtract 16 from both sides

[tex](x+4)^2+3=0[/tex]

So this is as far as you can go since you cannot take the square root of a negative number

Answer:

Yes, at positive x coordinates

Step-by-step explanation:

Find the equation of g(x)

Given ordered pairs of g(x):  (-1, -22)  (0, -20)  (1, -18)

[tex]\sf let\:(x_1,y_1)=(0,-20)[/tex]

[tex]\sf let\:(x_2,y_2)=(1,-18)[/tex]

[tex]\sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-18-(-20)}{1-0}=2[/tex]

Point-slope form of linear function: [tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-(-20)=2(x-0)[/tex]

[tex]\implies \sf y=2x-20[/tex]

Substitute the equation of g(x) into the equation of the circle and solve for x

Given equation:  [tex]y^2+x^2=100[/tex]

[tex]\implies (2x-20)^2+x^2=100[/tex]

[tex]\implies 4x^2-80x+400+x^2=100[/tex]

[tex]\implies 5x^2-80x+300=0[/tex]

[tex]\implies x^2-16x+60=0[/tex]

[tex]\implies x^2-10x-6x+60=0[/tex]

[tex]\implies x(x-10)-6(x-10)=0[/tex]

[tex]\implies (x-6)(x-10)=0[/tex]

Therefore:

[tex](x-6)=0 \implies x=6[/tex]

[tex](x-10)=0 \implies x=10[/tex]

So the linear function g(x) will intersect the equation of the circle at positive x coordinates.

The area of the rhombus with length of diagonals 12 cm and 12 cm is 72 centimetre squared.

The area of a rhombus can be represented mathematically as follows:

area of a rhombus  = ab / 2

where

a = 6 + 6 = 12 cm

Therefore, let's find b

tan 45 = opposite / adjacent

tan 45 = 6 / x

x = 6 / tan 45

x = 6 / 1

x = 6

b = 6 + 6 = 12 cm

Therefore,

area = 12 × 12 / 2

area = 144 / 2

area = 72 cm²

Answer:

A number less than or equal to 3 will add one point.

Step-by-step explanation:

The answer above is correct.

Answer:

y=e^x - 4

Step-by-step explanation:

The log functions decrease with increasing x.  The line shown increases as x increases, so it must be one of the two e^x equations.  We can decide which one by calculating which equation povides the correct values to match the two points the curve crosses the y and x axes.

The graph shows the line crossing the y axis at -3 (0,-3)

It shows it crossing the x axis at a little over 1, perhaps 1.4 (1.4,0).  

When x=0, e^0 = 1.  

Look at the point (0,-3):  

We know the e term will be 1 (e^0 = 1), so for y to be -3, we need to subtract 4:  The form e^x - 4  would yield a value for y, when x is 0, of y = 1 - 4 or -3.

Check the other point (1.4,0):

y = e^1.4  is equal to 4.00

y = 4.00 - 4

y = 0

This point is also correct (1.4,0)

The correct equation is y=e^x - 4
