Find the arc length of the semicircle.

Answers

Answer 1

Answer:

34.54 units

Step-by-step explanation:

The length of the circle:

C = 2πr

Semicircle is half of it:

C/2 = πr = 3.14*11 = 34.54 units

a = 8 b = c = 10

Answers

Answer:

B= 6

Step-by-step explanation:

pythagorean theorem formula is a² + b² = c²

so: 8² + b² = 10²

then: 64 + b² = 100

subtract 64 from both sides to get b²= 36

square root 36 and you get 6 for b

answer: B= 6

The graphs of rational functions m and n have the same vertical asymptotes, and both have a single x-intercept at x = 5.
Which equation could represent function n?

A.
n(x) = 5m(x)
B.
n(x) = m(x) + 5
C.
n(x) = m(x − 5)
D.
n(x) = m(x + 5)

Answers

Answer:

Step-by-step explanation:

We are given two rational functions m(x) and n(x) that have the same vertical asymptotes both with a single x-intercept at x = 5.

The correct choice will be A.

Recall the transformations of functions.

B represents m(x) being shifted up 5 units. If the function is shifted up, the vertical asymptotes will be the same, but the x-intercept will change.

C represents m(x) being shifted 5 units to the right. This changes both the x-intercept and the vertical asymptotes.

Likewise, D represents m(x)being shifted 5 units to the left. Again, this will change both the x-intercept and the vertical asymptotes.

Therefore, the only choice left is A. It represents a vertical stretch by a factor of 5. This preserves the x-intercepts and the vertical asymptotes. Consider, as an example, the function:

[tex]\displaystyle m(x)=\frac{x-5}{(x-3)(x-7)}[/tex]

If n(x)=5m(x), we can see that:

[tex]\displaystyle n(x)=\frac{5(x-5)}{(x-3)(x-7)}[/tex]

So, the x-intercepts and vertical asymptotes are preserved.

–3(–2h + 3) =

Answers

Answer: 6h - 9

=================================================

Explanation:

The outer term -3 is multiplied by every term inside

We get the following

-3 times -2h = 6h-3 times 3 = -9

This means the original expression becomes 6h-9. I applied the distributive property.

-3(-2h+3)=6h-9
Because a negative times a positive equals a positive and a negative times a positive equals a negative

Answer:

x = 45

Step-by-step explanation:

If we assume that ray GJ lies between rays GF and GH, then the angle sum theorem tells us ...

∠FGH = ∠FGJ +∠JGH

140° = 95° +x°

45° = x° . . . . . . subtract 95° from both sides

x = 45

_____

Alternate solution

There is an alternate solution if ray GF lies between ray GH and ray GJ.

∠JGH = ∠FGJ +∠FGH

x° = 95° +140°

x° = 235°

x = 235

Without some additional information, we cannot tell which assumption we should make about the geometry.

Alison's dog is 6 pounds more than five times the weight of gales dog what algebraic equation could you make to find G which is the way to gail's dog.

Answers

Answer:

g = (x - 6) / 5

Step-by-step explanation:

Given:

Let :

Alison's dog = x

Gale's dog = g

x is 6 pounds more than 5 times g

Mathematically,

x = 5g + 6

We can solve for g ;

x - 6 = 5g

Divide both sides by 5

(x - 6) / 5 = g

Answers

Answer:

Hope this helps 0>0

Step-by-step explanation:

Let x represent the number of sales each man had.

For Salesman A, he earns $65 per sale; this is 65x.

For Salesman B, he earns $40 per sale; this is 40x. We also add to this his weekly salary of $300; this gives us 40x+300.

Since their pay was equal, set the two expressions equal:

65x = 40x+300

Subtract 40x from each side:

65x-40x = 40x+300-40x

25x = 300

Divide both sides by 25:

25x/25 = 300/25

x = 12
