The given equation is 4x^2=x^3+2x.
On the left side it has 4x² and on the right side the expression is x³+2x.
So, if we have any system of equations in which we have these two expression which will be equal to any other variable then we can use that system of equations to find the roots.
Now notice that in option D it's given,
y=4x² and y=x³+2x.
So, if we will equate this equations then we will get the same above equation which will be use to find the roots.
So, D is the correct choice.
Answer:
increased 12
Step-by-step explanation:
Rounding to the nearest hundredth would equal a more accurate and precise answer since more decimals are present. Your answer would be even more accurate if you rounded to the nearest thousandth.
Answer:
62 degrees
Step-by-step explanation:
If two angles are complementary, it means that their sum is 90degrees
Hence if m<a and m<b are complementary, then;
m<a + m<b = 90
Given
m<a = 28degrees
Required
m<b
Substitute into the formula as shown;
28 + m<b = 90
m<b = 90 - 28
m<b = 62degrees
Hence the measure of angle b is 62 degrees
