Answer:

A.25

Step-by-step explanation:

Both sides of this obtuse angle are the same, which means it has to have the same degrees. If you plug these answer choices into x, it has to equal 132. Thus, 25 was the correct answer.

Answer:

50°

Step-by-step explanation:

Given figure is a quadrilateral. Sum of the measures of all the angles of a quadrilateral is 360°.

Therefore,

(x + 10 )\degree + 2x  \degree + x\degree  + 3x\degree  = 360 \degree \\  \\ (7x + 10 )\degree = 360 \degree \\  \\  7x + 10 = 360 \\  \\ 7x = 360 - 10 \\  \\ 7x = 350 \\  \\ x =  \frac{350}{7}  \\  \\ x = 50

Suppose that the functions r and s are defined for all real numbers x as follows. =rx−x5 =sx+2x3 write the expressions for ·rsx
PolarNik [594]

Although the question's print is not clear, to the best of my knowledge, as I can see, We are given that:

r(x)=-x^5 and s(x)=2x^3

No, we know that, by definition:

(r.s)(x)=r(x)\times s(x)

\therefore (r.s)(x)=-x^5\times 2x^3=-2x^8

Thus, for the functions r and s which are defined for all real numbers x, the answer to the question asked is:

(r.s)(x)=-2x^8

In the spring a young maple is 18 feet tall. Over the summer it grows 8%. How
Setler79 [48]

Answer:

At end of summer, the Maple is 19.44 feet

Step-by-step explanation:

We need to find 8% of 18 feet and add it to 18 to get the new height.

To get percentage to decimal, we need to divide by 100. Hence

8/100 = 0.08

8% of 18 is:

18 * 0.08 = 1.44 feet

Now, we need to add this to 18 feet. We have:

18 + 1.44 = 19.44 feet

What measurements of a cone can be found if you know the volume and height
Liula [17]

Answer: The base area, diameter, and radius can be found out by discovering the volume and height. Substitute the values to the corresponding variables into the formula, and then solve by simplifying and undoing operations to isolate the variable to find the diameter which is double the radius.
