Answer:

Step-by-step explanation:

Adjacent angles of a parallelogram add up to 180 degrees, meaning that (3x)+(x+60)=180 degrees. You can use this to set up the following equation:

3x+x+60=180

4x=120

x=30 degrees. Hope this helps!

P(x) =0.02x³+0.04x²+0.3x+1.2.Evaluate P(18) by direct substitution and by applying the remainder theorm

tatiyna

Answer:

136.2

Step-by-step explanation:

Plugin x = 18 in the polynomial.

P(x) = 0.02x³ + 0.04x² + 0.3x + 1.2

P(18)= 0.02*(18)³ + 0.04*(18)² + 0.3*18 + 1.2

= 0.02 * 5832 + 0.04*324 + 5.4 + 1.2

= 116.64 + 12.96 + 5.4 + 1.2

= 136.2

Rewrite the expression in exponential form

zheka24 [161]

Answer:

$x^{\frac{1}{4} }$

Step-by-step explanation:

A root can be converted to a power by taking the base of the root (in this case 4) and making it 1 over that number, so in this case $\frac{1}{4}$

If it were the fifth root you would make it to the 1 over 5 power.

<1 and <2 are complementary angles. The measure of Z1 is 41°. The measure of <2 is 7(x - 1)º. Find the value of x.

kogti [31]

Answer:

i think its x=16 or x=11

Step-by-step explanation:

∠2 = 90 - 42 = 48 degrees

3x degrees = 48 degrees

3x = 48

x = 16
