Answer:

[tex] \frac { 5\sqrt{21} }{ - 7} [/tex]

Step-by-step explanation:

Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r

[tex] {7}^{2} + {24}^{2} = {r}^{2} [/tex]

49+576=

[tex] {c}^{2} [/tex]

525=c^2

[tex] \sqrt{525} = 5 \sqrt{21} [/tex]

So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals

[tex] \frac{x}{r} [/tex]

cos=

[tex] \frac{ - 7}{5 \sqrt{21} } [/tex]

then we find secant which is the reciprocal of cos so we flip the numbers and that equals

[tex] \frac{5 \sqrt{21} }{ - 7} [/tex]

Answer:

Sum: 34 + 17 = 51

Difference: 34 - 17 = 17

Step-by-step explanation:

math

Answer:

34, 17

Step-by-step explanation:

We can first get the two equations x + y = 51 and x - y = 17 by calling the first number x and the second one y. Next, we can add y on both sides in the second equation to get that 17 + y = x. Now, since we know that 17 + y is equal to x, we can substitute 17 + y in for x in the first equation. We get that 2y + 17 = 51, and if we subtract by 17 on both sides and get that 2y = 34. This means that y is equal to 17, meaning that x is 34.

area of parallelogram=base×height=32×25=800cm²

Answer:

Step-by-step explanation:

If you change the bases to the same number, the exponents must equal each other.

Answer and Step-by-step explanation:

First, we find the area of one area of a face on the cube.

6.5 × 6.5 = 42.25

Now, we times 42.25 by 6, since there are 6 faces on a cube.

42.65 × 6 = 253.5

The answer is 253.5

Answer:

They are both identical cubes which makes it much easier.

Work out the volume for just one first.

The formula for volume is:

l x w x h

However, since it is a cube, all lengths are the same.

3 x 3 x 3 = 27

Now multiply it by 2 to get the volume of both combined:

27 x 2 = 54.

In short, your answer is  54cm 3

Answer:

1: 42

2: 107.6 °F

Step-by-step explanation:

For question 1 you insert the x and y values into the expression:

8 × 5 = 40 (xy = 40)

40 - 8 = 32 (xy - x = 32)

2 × 5 = 10 (2y = 10)

32 + 10 = 42 (xy - x + 2y = 42)

For question two you insert the celsius value into the expression:

9/5 × 42 = 75.6 (9/5C = 75.6)

75.6 + 32 = 107.6 (9/5C + 32 = 107.6)

Answer:

Domain is all real numbers greater than or equal to 7. Range is all real numbers greater than or equal to 9.

Step-by-step explanation:

The domain is possible x-values while the range is possible y-values. This question look like

[tex] \sqrt{x - 7} + 9[/tex]

The domain of square root function cant have a the radical inside being a negative number because we can't take the sqr root of a negative number and graph it on a cartisean plane We can take the sqr root of 0 . So we set x-7=0. And which x=7 so the domain is all real numbers that are equal to or greater than 7. The range of a sqr root function can only yield any positive y-values. So we must find the lowest point of it. Since the lowest x value we can possible use is 7 we plug it in

[tex] \sqrt{7- 7} + 9[/tex]

which equals 9. So the range is all real numbers greater than or equal to 9.

Answer:

2.5

The lowest point on the graph, or the minimum is at f(x)= 2.5

The minimum value of the given periodic function is, 2.5

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

A periodic function,

Period  = 3π

The value of the function is in the range of (2.5, 4.5)

So,

Maximum value = 4.5

Minimum value  = 2.5

Thus, the minimum value is 2.5

Answer:

19% alcohol solution = 65 ounces

37% alcohol solution = 25 ounces

Step-by-step explanation:

Let

19% alcohol solution = x

37% alcohol solution = y

x + y = 90 (1)

0.19x + 0.37y = 90*0.24

0.19x + 0.37y = 21.60 (2)

from (1)

x = 90 - y

Substitute into (2)

0.19x + 0.37y = 21.60

0.19(90-y) + 0.37y = 21.60

17.1 - 0.19y + 0.37y = 21.60

- 0.19y + 0.37y = 21.60 - 17.1

0.18y = 4.5

y = 4.5/0.18

y = 25 ounces

x + y = 90 (1)

x + 25 = 90

x = 90 - 25

x = 65 ounces

Answer:

7 ÷ 9 = 0.77777777777

= 0.778

The given fraction 7/9 as a decimal rounded to 3 decimal places is 0.778.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

To convert a fraction to a decimal, we need to divide the numerator by the denominator.

Here, we have:

7/9 = 0.777777...

7 divided by 9 gives us a repeating decimal of 0.7777777... and so on.

To round this to 3 decimal places, we need to look at the fourth decimal place. If it is 5 or greater, we round up the third decimal place. If it is less than 5, we simply leave the third decimal place as is.

In this case, the fourth decimal place is a 7, which means we need to round up the third decimal place.

Therefore, 7/9 as a decimal rounded to 3 decimal places is 0.778.

Hello there!

Your question asks to find what was the size of the population in 2017

Answer: 6,721

In order to solve this problem, we're going to need to use the given information in the question in order to find the population in 2017.

Key information:

In 2010, population was 6500

In 2014, population increased by 10% from 2010

In 2017, population decreased by 6% from 2014.

With the information above, we can solve the problem.

We're going to start with 6500 as our starting population.

We know that the population increased by 10% in 2014, so we would multiply 6500 by 1.10.

7 teams with 6 girls and 8 boys on each team

Step-by-step explanation:

Both 42 (girls) and 56 (boys) are divisible by 7 (getting 6 and 8).

Therefore, there would be 6 girls and 8 boys on each team.

The ratio would be 6 girls:8 boys per team.

Check:

6•7=42 ––(6 girls amongst 7 teams = 42 girls total)

8•7=56 ––(8 boys amongst 7 teams = 56 boys total)

Answer:

54 1/3 yards

Step-by-step explanation:

Yards needed = Required net yards - Yards already ran

We know that Required net yards = 20

We can set yards already ran to -34 1/3

Yards needed = (20) - (-34 1/3)

= 20 + 34 1/3                   Subtracting a negative makes it a +

= 54 1/3

They have to get 54 1/3 yards on their next play to get a first down
