what is [tex]\frac{-8 + \sqrt{-20} }{24}[/tex]?

Answer:

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.

Answer:

Step-by-step explanation:

Solve for x=0 and x=1

y(0)=2(3^0)=2(1)=2 so (0,2) is a point.

y(1)=2(3^1)=2(3)=6 so (1,6) is a point.

Only graph B has those two points.

Answer:

13 and 14

Step-by-step explanation:

From the inequality

x + 2 x + 6 < 50

we work out the answer for x isolating it on one side of the inequality as shown below

3 x + 6 < 50

3 x < 50 - 6

3 x < 44

x < 44/3  ≅ 14.6666...

Therefore, select from the set the numbers:  13 and 14.

Answer:

Number of dogs (x) | Amount charged to walk a dog (y)

1 | 20

2 | 40

3 | 60

4 | 80

5 | 100

6 | 120

7 | 140

8 | 160

Step-by-step explanation:

Charge for walking a dog = $20 per dog

Number of dogs = x

Amount charged to walk a dog in a day = y

Unit rate = 20

Equation to represent this is: y = 20x

Let's use this to form a table for walking 1 to 8 dogs:

For 1 dog (x):

y = 20(1) = $20

For 2 dogs (x):

y = 20(2) = $40

For 3 dogs(x):

y = 20(3) = $60

For 4 dogs:

y = 20(4) = $80

And so on till we get to tl8 dogs.

This, we should have the following table:

Number of dogs (x) | Amount charged to walk a dog (y)

1 | 20

2 | 40

3 | 60

4 | 80

5 | 100

6 | 120

7 | 140

8 | 160

33.85 or 32.75 sorry if I am wrong

Step-by-step explanation:

for this one you have you multiply 17 by itself like this 17x17=289 but you also have to do it with the 28 to like this 28x28=784, now what you do it add up the 289+784=1,073 then you square root 1,073 which gives you 32.75 round it to the nearest tenth of needed so your will be between 33.85 or 32.75

Answer:

5

Step-by-step explanation:

First, find the equation of the line:

put it in the form y = mx + b where m is the slope and b is the y-intercept

You already have m = 2, so y = 2x + b.

Then, since you know (1, 3) is a solution so you can plug x = 1 and y = 3 into the equation to find out what b is.

3 = 2 * 1 + b

3 = 2 + b

1 = b

This means the equation of the line is y = 2x + 1.

Then, since you're trying to find out what y is when x = 2, you can plug in x = 2 into the equation:

y = 2 * 2 + 1

y = 4 + 1

y = 5

5 is the answer

Answer:

¼(√6 + √2)

Step-by-step explanation:

We want to find cos (π/12) in surd form.

Now, cos (π/12) can be expressed as;

cos [(π/4) - (π/6)]

Now, from trig derivations we know that;

Cos (A - B) = CosACosB + sinAsinB

Thus;

cos [(π/4) - (π/6)] = cos(π/4)Cos(π/6) + sin(π/4)sin(π/6)

Now, in surd form;

cos(π/4) = sin(π/4) = (√2)/2

Cos(π/6) = (√3)/2

sin(π/6) = 1/2

Thus, Plugging in relevant values to get;

cos(π/4)Cos(π/6) + sin(π/4)sin(π/6) = ((√2)/2 × (√3)/2) + ((√2)/2 × 1/2)

This gives;

((√6)/4) + ((√2)/4) = ¼(√6 + √2)

Answer:

3?

Step-by-step explanation:

Answer:

x² + 2x - 6

Step-by-step explanation:

= f(x) + g(x)

= (2x + 1) + (x² - 7)

= 2x + 1 + x² - 7  

= 2x - 6 + x²  

= x² + 2x - 6

Answer:

Department Store:

7(18.75)+8= 139.25

Gas Station:

18.75+22= 40.75

Step-by-step explanation:

The mistake is 7x+8+x+22 should not equal 90. It should equal 180 degrees because the two angles are supplementary angles. (It forms a straight line)

Correct equation and how to solve for X:

7x+8+x+22=180

Answer:

The price of the bicycle after the discount is 357 lei

Step-by-step explanation:

The given question says, "The bicycle costs 420 lei. Its price is reduced by 15%. How much will the bike cost after the discount."

Cost price of the bicycle = 420 lei

Discount = 15%

We need to find the price of the bicycle after the discount. It can be calculated as follows :

[tex]P=420\times \dfrac{15}{100}\\\\=63[/tex]

Price = 420 -63

= 357 lei

Hence, the price of the bicycle after the discount is 357 lei.

Answer:

The correct answer is C. 27 ft, 45 ft, 63 ft.

Step-by-step explanation:

Given that the ratio of the measures of the sides of a triangle is 3: 5: 7, and its perimeter is 135 feet, in order to find the measure of each side of the triangle, the following calculation must be performed:

3 + 5 + 7 = 15

135/15 = 9

9 x 3 = 27

9 x 5 = 45

9 x 7 = 63

Therefore, the measures of the sides of the triangle are 27 ft, 45 ft, and 63 ft.

Answer:

b = 34

m = 5

f(t) = 5x+34

Step-by-step explanation:

f(0) = 34, so that is its y intercept.

f(t) contains (0,34) and (8,74), which can be used to find the slope:

[tex]\frac{74-34}{8-0}=\frac{40}{8}=5[/tex]

Answer:

the 9 in the tenths place is 10 times bigger than the one in the hundredths place

Step-by-step explanation:

The value of the 9 in the tenth place is "10 times" the value of the 9 in the hundredth place.

Place value strategies are defined as math strategies that use to assist you in resolving your elementary math problems, using your place values, such as tens and hundreds.

The decimal we are examining is 3.9928.

The 9 in tenth place has a value of 0.9.

The value of 9 in the hundredth place is 0.09

The fraction of the 9 in the tenth place is now the 9 in the hundredth place.

To get this, simply multiply the value of 9 in the hundredth place by the value of 9 in the tenth place.

Mathematically, that would be;

0.09/0.9 = 0.1 = 1/10

This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place

So you can complete the statement by dragging and dropping "10 times" into the response area.

Answer:

Step-by-step explanation:

You can tell by looking at the form of each equation.

y = tx

This is a straight line that passes through the origin, so it symmetric with respect to the origin.

y = x²+1

This is an up-opening parabola with vertex at (0,1), so it is symmetrical about the y-axis.

y = x²+x = (x+½)² - ¼

This is an up-opening parabola with vertex at (-½,-¼). Not symmetrical to either axis nor to the origin.
