When we add the angle that has x° and the angle that has (4x-20)° we need to get 180°.

Mathematically: x° + (4x-20)° = 180°. 

We solve for x:

x°+4x°-20°=180°, we put all numbers that we know on the right side and all unknowns on the left side:

5x°=200°, we divide by 5 and get:

x=40°

So the correct answer is D. x=40°.

For the polynomial x5 – 2x6 + 3, which of these statement(s) is true? Select all that apply A. The polynomial is a trinomial. B.
Evgen [1.6K]

Answer:

A, B and D

Step-by-step explanation:

A. The polynomial is a trinomial.

A trinomial refers to a polynomial with three terms. This option is correct.

B. The degree of the polynomial is 6.

Degree refers to the highest power in the polynomial. This option is correct.

C. The leading coefficient is 1

This is false. The leading coefficient is the coefficient of the variable bearing  the degree of the polynomial. This is wrong.

D. Written in standard form, the polynomial is –2x6 + x5 + 3.

This is correct.

If $8259 principal is invested in a savings account that pays 5.25% interest compounded continuously how much money will be in t
VMariaS [17]

Answer:

A(10) = $13,961.50

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 5.25/100

r = 0.0525 rate per year,

Then solve the equation for A

The formula is given as:

A = Pe^rt

P = 8259

r = 0.0525

t = 10 years.

Hence,

A = 8,259.00 × e^(0.0525×10)

A = $13,961.50

Therefore, the money that will be in the account after 10 years is $13,961.50

tester [92]

Answer:

see below

Step-by-step explanation:

1.  < 4 is the exterior angle of a triangle   given

2.  <1 + <2 + <3 =180   basic property of triangles

3.  <3 + <4 are a linear pair    <3 and <4 are adjacent and form a straight line

4. <3 and <4 are supplementary angles  supplementary angles are linear pairs

5.  <3 + <4 = 180   The definition of supplementary angles are that they add to 180 degrees

6.  <1 + <2 + <3 = <3+ <4  Substitute <3 + <4  for 180 in equation from step 2

7 <1 + <2 = <4   Subtract <3 from each side using the subtraction property of equality
