1.EB is parallel to FC because they are on opposite sides and will never touch

2.scalene triangle

right angle

isosceles

3. supplementary angles add to 180 degrees

180-62=118

complementary angles add up to 90

90-62=28

4. 180 - 68 - 38 = 74

5. 6 sides=hexagon

8. sides= octagon

9. sides = nonagon

10. supplementary angles add to 180 degrees

so angle EOC is supplementary to EOF

Madison and Tanisha went out to lunch. The bill came to $18.94. Madison knows that her lunch cost 9.72. How much did Tanisha's l

Finger [1]

Answer:

Tanisha's lunch cost $9.22.

Step-by-step explanation:

Given that,

Total bill = $18.94

Cost for Madison cost = $9.72

Total cost = Tanisha's lunch + Madison's lunch

18.94 = Tanisha's lunch + 9.72

Tanisha's lunch = 18.94 - 9.72

Tanisha's lunch = 9.22

So, Tanisha's lunch cost $9.22.

Bob bought a new book and paid $2.10 tax on the book. If the tax rate was 7 ½%, what was the cost of the book?

scoray [572]

$15.75
2 x 7.5 = 15
0.10 x 7.5 = 0.75
15 + 0.75 = $15.75
Hope this helped

If g(3) = 5 and g(-1) = 5, explain why g(x) does not have an inverse.

Alenkinab [10]

g(x) cannot have an inverse because it gives the same output value for two individual input values.

In this case, g(x) is 5 when x is both 3 and -1. Hence, g(x) does not have an inverse.

Let me know if you have any questions, thanks!

What is the asymptote for the graph of this logarithmic function?<br><br> f(x) = log3(x – 1)

Pepsi [2]

Answer:

Vertical Asymptote:

$x=1$

Horizontal asymptote:

it does not exist

Step-by-step explanation:

we are given

$f(x)=log_3(x-1)$

Vertical asymptote:

we know that vertical asymptotes are values of x where f(x) becomes +inf or -inf

we know that any log becomes -inf when value inside log is zero

so, we can set value inside log to zero

and then we can solve for x

$x-1=0$

we get

$x=1$

Horizontal asymptote:

we know that

horizontal asymptote is a value of y when x is +inf or -inf

For finding horizontal asymptote , we find lim x-->inf or -inf

$\lim_{x \to \infty} f(x)= \lim_{x \to \infty}log_3(x-1)$

$\lim_{x \to \infty} f(x)=log_3(\infty-1)$

$\lim_{x \to \infty} f(x)=undefined$

so, it does not exist
