Answer:

D. twenty-eight and nine tenths

Answer:

A = 60 degrees

C = 8 m

Step-by-step explanation:

Whenever we are faced with a geometry problem, and we have a right-angled triangle within the problem, we are to remember Pythagoras' Law first, and the fact that a right-angled triangle always has an angle that measures 90 degrees.

We will also need to know that the sum of the angles in a triangle is 180 degrees.

Therefore, angle A will be = 180 - (90 +30) = 60 degrees

From Pythagoras' Law, we can see that [tex]c= tan 30 \times 8\sqrt{3} =8[/tex]

therefore, line c = 8m

Answer:

-15%

Step-by-step explanation:

percentage change is calculated by

(new price - old price) / old price

(850 - 1000) / 1000

please give thanks by hitting heart button! :)

Answer:

15%

Step-by-step explanation:

1. Subtract the sale price from the normal price.

$1000 - $850 = $150.

2. Divide this amount by the original price.

$150/$1000 = 0.15

3. Multiply by 100 to get the %.

0.15 x 100 = 15%

Answer:

B. Baseball cap

Step-by-step explanation:

Given that:

Total money available with Annabeth = $29.00

Amount at which T-shirt was bought = $15.32

Things that Annabeth wants to buy:

Soccer ball for the price of $12.87 or

Baseball cap for the price of $8.39 or

Set of shin guards for the price of $14.98 or

Water bottle for the price of $5.93

The equation that can be used to find the cost of most expensive item with the remaining amount of money:

$15.32 + [tex]c[/tex] = $29.00

[tex]\Rightarrow c = 29 - 15.32\\\Rightarrow c= \$13.68[/tex]

Cost of items that can be bought in the decreasing order is:

Cost of pair of shin guards ( $14.98 ) > Cost of soccer ball ( $12.87 ) > Cost of baseball cap ($8.39) > Cost of water bottle ( $5.93 )

The most expensive item that can be bought is the Soccer ball at $12.87.

Answer is:

B. Soccer ball

Cost of shin guards is more than the amount of money remaining.

Answer:

5b - 3

Step-by-step explanation:

5b-3 is the algebraic expression for "3 less than the product of 5 and b"

Expression is a combination of variables, numbers and Operators.

The given sentence is

"3 less than the product of 5 and b"

Let us write the sentence in algebraic form.

We know that product of 5 and b means multiplication of 5 and b that means five times of b.

3 less than means subtracting 3 from another number.

So 3 less than the product of 5 and b is 5b-3.

Hence 5b-3 is the algebraic expression for "3 less than the product of 5 and b"

Answer:2/3

Step-by-step explanation:

Steps in pic below

Answer:

I will explain each step

3(x-y) / 2 =9

so first you have to make the equation equal to 0 so you can find the intercepts

3(x-y) /2  -9 =0

now simplify

3x-3y/2 -9 =0

2(3x-3y/2 -9)=0(2)

3x-3y-18

we will factor

3(x-y-6)

3=0

(x-y-6)=0

make the x=0 to find y and vise versa

(-y-6)=0

-y=6

y=6/-1 or -6

(x-6)=0

x=6/1 or 6

2/3x +4(y-2)=0

it is already equal to 0 to we simplify and factor

3(2/3x = 4(y-2)= 0(3)

2x+ 4y -8

2(x+y-4)

2=0

as we did in the last problem make x=0 then do the same to y

(y-4)=0

y=4

(x-4)=0

x=4

Step-by-step explanation:

Answer:

y = 4

Step-by-step explanation:

21 = 3(y + 3), Distribute

21 = 3y + 9, Subtract 9 on both sides

12 = 3y, Divide 3 on both sides

4 = y

Step-by-step explanation:

From the question, we are informed that a coach has 17 pompoms to give to her cheerleading team and that each cheerleader needs 2 pompoms to compete.

The greatest number of cheerleaders that can compete will be calculated as:

= 17 / 2

= 8 1/2

Therefore, the greatest number of cheerleader is 8.

There be 1 pompom remaining.

Kinetic Energy (K. E) = 25 J

Mass ( m) = 2 kg

Velocity or speed (v) = ?

We have the formula that

[tex]ke \: = \frac{1}{2} m {v}^{2} \\ or \: 25 = \frac{1}{2} \times 2 \times {v}^{2} \\ or \: 25 = {v}^{2} \\ or \: {5}^{2} = {v}^{2} \\ therefore \: v \: = 5 \: m |s[/tex]

it's speed is 5 m/s .

Hope it helps. :)

The speed of the body is 5 m/s

Applying the formular of kinetic energy

Kinetic energy: This can be defined as the energy posses by a moving body or that depends on the speed of a body.

The formular for kinetic energy is

E = mv²/2.................... Equation 1

Where E = Kinetic energy of the body, m = mass of the body, v = veocity/ speed of the body.

make v the subject of equation 1 above

v = [tex]\sqrt{2E/m}[/tex]................ Equation 2

From the question,

Given: E = 25 J, m = 2 kg

Substitute these values into equation 2

v = [tex]\sqrt{2*25/2}[/tex]

v = [tex]\sqrt{50/2}[/tex]

v = [tex]\sqrt{25}[/tex]

v = 5 m/s.

Thus, the speed of the body is 5 m/s

Answer:

First, let's define the transformations in a general way.

Vertical translation:

A vertical translation of N units is defined as:

g(x) = f(x) + N

if N is positive, the translation is up

if N is negative, the translation is down.

Horizontal translation:

A horizontal translation of N units can be written as:

g(x) = f(x - N)

if N is positive, the translation is to the right

if N is negative, the translation is to the left.

Reflected vertically (or a reflection over the x-axis)

This type of reflection changes the sign of the y component.

We can write those as:

g(x) = -f(x)

Then:

We start with the function:

f(x) = 2^x

First we reflect it vertically.

g(x) = -2^x

now we do a vertical translation of 5 units up, then:

g(x) = -2^x + 5

Now we do a translation of 3 units to the left, then we get:

g(x) = - 2^(x + 3) + 5

Then we already did the first step.

Now we want to find the domain for this function, the domain will be the set of the possible values of x that we can input in the function g(x).

Notice that in this function the denominator is never zero, so there are no values of x that generate problems here, so the domain will be the set of all real numbers, that can be written as:

(-∞, ∞)

3) Now we want to find the range, this is the set of the possible values of g(x).

The Largest value of g(x) will be when the exponential part tends to zero, this is for really small values of x, such that when x goes to minus infinity, -2^(x + 3) goes to zero.

Then:

g(-∞) ≈ 5

The maximum of the range is 5.

And we do not have a minimum, because as x increases the function will decrease infinitely.

Then the range will be:

(-∞, 5)

Step-by-step explanation:

13/10÷2/10

13/10×10/2

1.3×5

=6.5

Answer:

Part A: So the solution for 4 = 2x-1 is -2. Why they're intersecting is because x is -0.5 in both cases. 2/4, as we already know, is 0.5. Since, this -2/4, we can just make 0.5 negative, so -0.5. -0.5 times 4 = -2, so x is -0.5. For y = 2x-1, multiply -0.5 by 2, which would get you -1. Then after that subtract 1, for -2.

Part B:

Well, notice how none of the entries for y = 4x and y = 2x-1 match. That would mean the answer wouldn't be an integer. (Attachment is the table)

Part C:

First, graph both y = 4x and y = 2x-1. After that, find where the two equations' y-coordinates are the same (So, on a graph, where they intersect.). The y-coordinate in common is your answer.

Answer:

A: the intersection represents the answer because the place where it intersects is where the equations have the same x values.

B:  they intersect at the point (0,1)

C: plot the equations on an online graph and solve, Its almost impossible to draw an accurate continuing graph for an exponential equation. I recommend desmos.
