Hi um if your so kind please do 31,33,35,37 if you do thank so much

Ludmilka [50]

Answer:

31) They divided by 100, they're suppose to times 0.86 by 100 instead, which will be 86%

33) 0.34 x 100=34%

35) we do the inverse to turn it back into

a decimal which will be 0.36

$\frac{36}{100} = \frac{18}{50} = \frac{9}{25}$

36) 16.24÷100=0.6424

$\frac{16.24}{100} = \frac{8.12}{50} = \frac{4.6}{25}$

Which of the following is a polynomial with roots 2, 3i, and -3i?

solniwko [45]

Since the roots are 2,3i, and -3i, you can write it as

(x-2)(x-3i)(x+3i)=(x-2)(x^2+9)=x^3-2x^2+9x-18.

The parallelogram ABCD below, line AC is a diagonal, the measure of angle ABC is 40, and the measure of angle ACD is 57. What is

Strike441 [17]

Answer:

Using properties of parallelogram and angle sum property of a triangle in the figure as shown below in the attachment

In parallelogram ABCD, AC is a diagonal.

Given: $\angle ABC = 40^{\circ}$ and $\angle ACD= 57^{\circ}$

As, we know that opposite angles in parallelogram are equal.

therefore,

$\angle ABC =\angle ADC= 40^{\circ}$

Now, in ΔADC

Sum of the measures of angles in a triangle is 180 degree.

$\angle ACD+ \angle ADC+\angle DAC =180^{\circ}$

Substituting the values of $\angle ADC= 40^{\circ}$ and $\angle ACD= 57^{\circ}$ we have;

$57^{\circ}+40^{\circ}+\angle DAC =180^{\circ}$

$97^{\circ}+\angle DAC =180^{\circ}$

Subtract $97^{\circ}$ from both sides we get

$\angle DAC =180 -97 =83^{\circ}$

Therefore, the measure of angle CAD is $83^{\circ}$ .
