Schach [20]

Answer:

The leg measures 14.14 cm

Step-by-step explanation:

The "40 - 40 - 90" special right triangle is an isosceles right triangle because two angles measures the same. (Check the picture)

The legs are the same.

The hypotenuse is:

a × √2

From the question, the length of the hypotenuse is 20 cm.

20 = a × √2

20 ÷ √2 = a

a = 10√2 ≈ 14.14 cm

Question is attached, Don't worry explaining too much just make sure the answer is correct :))
garik1379 [7]

Answer:

The image below will explain the question

To figure out the length of portion BC, we will use the trigonometric ratio below

\begin{gathered} \sin\theta=\frac{opposite}{hypotenus} \\ oppsite=BC \\ hypotenus=8in \\ \theta=35 \end{gathered}

By substituting the values, we will have

\begin{gathered} \sin(\theta)=\frac{oppos\imaginaryI te}{hypotenus} \\ \sin35=\frac{BC}{8} \\ cross\text{ multiply, we will have} \\ BC=8\sin35 \end{gathered}

Hence,

The final answer is

\Rightarrow8\sin35^0

The FOURTH OPTION is the right answer

Describe the transformation that occurred on f(x) to create g(x).
asambeis [7]

Answer:

f(x) translated 3 units to the left and 8 units down, there is no reflection occurred

Step-by-step explanation:

* Lets revise some transformation for the functions

- If the function f(x) reflected across the x-axis, then the new

 function g(x) = - f(x)

- If the function f(x) reflected across the y-axis, then the new

function g(x) = f(-x)

- If the function f(x) translated horizontally to the right  

by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

by k units, then the new function g(x) = f(x) – k

* Now lets study the problem

∵ g(x) = 2(x + 3)² - 8

# x + 3 ⇒ means f(x) translated 3 units to the left

# -8 ⇒ means f(x) translated 8 units down

# There is no reflection occurred

Luis has a $10 bill and three $5 bills. He spends $12.75 on the entrance fee to an amusement park and $8.50 on snacks. How much
salantis [7]

Answer:

She has a total of $3.75 left

Step-by-step explanation:

Step 1

Express the amount of money Luis had in the beginning as follows;

A=E+R

where;

A=initial amount he had at the beginning

E=total expenditure

R=total remainder after spending

In our case;

A=(1×10)+(3×5)=$25

E=Amount spent at amusement park+amount spent on snacks

E=(12.75+8.50)=$21.25

R=unknown=r

Step 2

Substitute the values in the expression and solve for A;

25=21.25+r

r=25-21.25=3.75

r=3.75

She has a total of $3.75 left
