HELP IM BEING TIMED ANSWER FAST PLEASE

Answer:

7. about 41.8 degrees or 0.72972 radians (used [tex]sin^{-1} (\frac{4}{6} )[/tex], because the given leg is opposite from the angle)

8. about 50.4 degrees or 0.87946 radians (used [tex]tan^{-1} (\frac{29}{24} )[/tex])

9. about 12.8 degrees or 0.224 radians (used [tex]sin^{-1} (\frac{12}{54} )[/tex])

10. about 51.3 degrees or 0.8957 radians (used [tex]cos^{-1} (\frac{25}{40} )[/tex], given leg is opposite from angle)

Step-by-step explanation:

S.O.H.--C.A.H.--T.O.A

sine = opposite (to angle)/hypotenuse

cosine = adjacent (to angle)/hypotenuse

tangent = opposite (to angle)/adjacent (to angle)

I didn't know if it was degrees or radians, so I did both! I saw you on the film question asking for help, so I just wanted to do so! Have a great day!

Answer:

Linear equations are an important tool in science and many everyday applications. They allow scientist to describe relationships between two variables in the physical world, make predictions, calculate rates, and make conversions, among other things. Graphing linear equations helps make trends visible.

Answer:

5h ≤ 20 or h ≤ 4

Step-by-step explanation:

Lia walks at a rate of 5 miles per hour.

Lia has a goal of walking at least 20 miles

Let h be the number of hours she should walk in order to meet or exceed her goal.

At least in inequality means ≤. ATQ,

5h ≤ 20

Dividing both sides by 5.

h ≤ 4

So, she should walk atleast 4 hours. Hence, the correct option is (b).

1. Supplementary

2. Complementary

3. Adjacent angles

4. Vertically opposite angles

Answer:

A. The maximum represents the most amount of pencil price in dollars sold for the most amount of profit and the x-intercepts represent the profit when it is. The intervals at where the function increases represents a bigger profit for a price, whereas a decreasing interval represents a lower profit for a price.

Step-by-step explanation:

my answer for my test

The average rate of a function is 20 and for every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

Average rate of a function:

= (160-100)/5-2

= 20

For every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

Because prices are rarely negative, the domain is most likely confined to 0≤x. The price may be set so high that it yields a loss, but that is not a viable option. As a result, x ≤10 is the upper limit of the sensible domain.

Thus, the average rate of a function is 20 and for every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

Answer:

£3,692

Step-by-step explanation:

First four years

A = p(1 + r/n)^nt

P = £2350

r = 4.2% = 0.042

n = 1

t = 4

A = p(1 + r/n)^nt

= 2350(1 + 0.042/1)^1*4

= 2350(1 + 0.042)^4

= 2350(1.042)^4

= 2350(1.5789)

= 2770.42

A = £2770.42

Next 6 years

P = £2770.42

r = 4.9% = 0.049

n = 1

t = 6

A = p(1 + r/n)^nt

= 2770.42(1 + 0.049/1)^1*6

= 2770.42(1 + 0.049)^6

= 2770.42(1.049)^6

= 2770.42(1.3325)

= 3691.59

A = £3691.59

Approximately £3692

Answer:

x^2 - 6x + 9

Step-by-step explanation:

(x-3)^2

(x-3)(x-3)

x^2 -3x -3x + 9

x^2 - 6x + 9

^2 means (x - 3) times itself twice.

(x - 3)(x - 3)             multiplying polynomials- Firsts, Outs, Inners, Lasts (FOIL)

                                 Firsts (x* x)   Outs (x*-3)   Inners (-3 * x)   Lasts (-3*-3)

xx -3x -3x +9            Combine like terms.

      -3x -3x             Adding/subtracting integers- same signs means you add          

                                     and keep the sign.

Answer:25

Step-by-step explanation:

Simply multiply by five on both the 5 and 4 and you get an equivalent fraction

Answer:

25/20

Step-by-step explanation:

I set up a proportion and to find the how 4 goes to 20, I divided 20/4 to get 5 and then I multiplied 5*5 to get 25.

You can also cross multiply.

Answer:

The sum of interior angles of a regular shape is found by doing no. of sides - 2 and times this by 180

8-2 =6

6x 180= 1080

then divide by 8 to find each angle

1080/8 = 135

Answer:

Step-by-step explanation:

Simplifying

7x + -2y = 1

Solving

7x + -2y = 1

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2y' to each side of the equation.

7x + -2y + 2y = 1 + 2y

Combine like terms: -2y + 2y = 0

7x + 0 = 1 + 2y

7x = 1 + 2y

Divide each side by '7'.

x = 0.1428571429 + 0.2857142857y

Simplifying

x = 0.1428571429 + 0.2857142857y

///////////////////////

Simplifying

2y = x + -1

Reorder the terms:

2y = -1 + x

Solving

2y = -1 + x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '2'.

y = -0.5 + 0.5x

Simplifying

y = -0.5 + 0.5x

Answer:

1) y = − 1 2 + 7 x 2

2)  x = 2 y + 1

Step-by-step explanation:

Subtract 7 x from both sides of the equation. − 2 y = 1 − 7 x Divide each term by − 2 and simplify.

y = − 1 2 + 7 x 2

Solve for x by simplifying both sides of the equation, then isolating the variable. x = 2 y + 1

Answer:

[tex]9\ \text{inches}[/tex]

Step-by-step explanation:

[tex]2\ \text{inches}[/tex] of the blueprint is [tex]3\ \text{feet}[/tex] of the actual concrete patio.

So [tex]1\ \text{inch}[/tex] of the blueprint = [tex]\dfrac{3}{2}\ \text{feet}[/tex] of the actual concrete patio

Width of the patio in the blueprint is [tex]12\ \text{inches}[/tex].

So [tex]12\ \text{inches}[/tex] of the blueprint = [tex]12\times \dfrac{3}{2}=18\ \text{feet}[/tex] of the actual concrete patio.

Now for the new blueprint [tex]1\ \text{inch}=2\ \text{feet}[/tex] of the actual concrete patio.

[tex]1\ \text{feet}[/tex] of the actual concrete patio = [tex]\dfrac{1}{2}\ \text{inch}[/tex] of the new bluprint.

So, [tex]18\ \text{feet}[/tex] of the actual concrete patio = [tex]\dfrac{18}{2}=9\ \text{inches}[/tex] of the new blueprint.
