if c is -1 the equation should be

4x² + 4x -1 = 0

not plus 1

I assume you want the coordinates of the zeros.

if c is indeed -1, they are at (-1.207 , 0) and (0.207 , 0)

if c is +1, as in the equation the only zero point is at (-0.5 , 0)

What's 26% of 600, I will give brainiest

Scrat [10]

Answer:

156

Step-by-step explanation:

Write 26% as

100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

100

of 600 =

100

× 600

Therefore, the answer is 156

If you are using a calculator, simply enter 26÷100×600 which will give you 156 as the answer.

Answer: $\frac{8}{3}\times \sqrt{\frac{2}{5}}$

Step-by-step explanation:

Given two upward facing parabolas with equations

$y=6x^2 & y=x^2+2$

The two intersect at

$6x^2=x^2+2$

$5x^2=2$

$x^2$ = $\frac{2}{5}$

x= $\pm \sqrt{\frac{2}{5}}$

area enclosed by them is given by

A= $\int_{-\sqrt{\frac{2}{5}}}^{\sqrt{\frac{2}{5}}}\left [ \left ( x^2+2\right )-\left ( 6x^2\right ) \right ]dx$

A= $\int_{\sqrt{-\frac{2}{5}}}^{\sqrt{\frac{2}{5}}}\left ( 2-5x^2\right )dx$

A= $4\left [ \sqrt{\frac{2}{5}} \right ]-\frac{5}{3}\left [ \left ( \frac{2}{5}\right )^\frac{3}{2}-\left ( -\frac{2}{5}\right )^\frac{3}{2} \right ]$

A= $\frac{8}{3}\times \sqrt{\frac{2}{5}}$

90 POINT QUESTION!!!

Aleks [24]

Answer: 9.19 ft

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.

Sin α = opposite side / hypotenuse

Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is the height of the top of the ladder above the ground.

Replacing with the values given:

Sin 45 = x/ 13

Solving for x

sin45 (13) =x

x= 9.19 ft

Feel free to ask for more if needed or if you did not understand something.

If the perimeter of a square is 236 inches, how long is each side?

Degger [83]

Answer:

59 inches

Step-by-step explanation:

a square has 4 equal sides

if the sum of all sides(perimeter) is 236 you can do the inverse of that and divide by 4

so your answer should be 59
