What are the solutions if 1/4x^2 =-1/2x+2?

Oksi-84 [34.3K]

Answer:

Step-by-step explanation:

$\frac{1}{4}x^{2}= \frac{1}{2}x +2\\\frac{1}{4}x^{2}- \frac{1}{2}x -2=0\\\frac{x^{2}-2x-8 }{4}=0\\\\x^{2}-2x-8=0\\ x^{2}-4x+2x-8=0\\x(x-4)+2(x-4) = 0\\(x-4) (x+2) = 0\\SO, \\x= 4 or x= -2$

vivado [14]

Given:

A prism has a base area of $20\pi$ square units and a volume of $120\pi$ cubic units.

To find:

The volume of the cylinder if the cylinder has the same base area and height.

Solution:

Volume of a prism is:

$V=Bh$

Where, B is the base area and h is the height of the prism.

The volume of cylinder is:

$V=\pi r^2h$

$V=Bh$

Where, r is the radius, h is the height of the cylinder and $B=\pi r^2$ is the base area.

Since base area and height of the cylinder are same as the prism, therefore, there volumes are equal.

Hence the volume of the cylinder is $120\pi$ cubic units.

The water level in a lake decreased by 2 1/4 inches in march and increased by 1 5/8 inches in april. Determine wether the water

mezya [45]

Change in level is given by :

C = increase in level - decrease in level.

Now,

Decrease in level in March is 2 1/4 = 9/4 inches.

Increase in level in April is 1 5/8 = 13/8 inches.

Putting value of these in above equation, we get :

C = 13/8 - 9/4

C = 13/8 - 18/8

C = -5/8 inches

Therefore, the overall level after April will decrease by 5/8 inches.

Hence, option 4. is correct.

The point slope form of the eqaution of the line that passes through (-5,-1) and (10, -7) is y+7= -2/5 (x - 10) what is the stan

stira [4]

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

$Ax+By=C$

We have the equation in point-slope form:

$y+7=-\dfrac{2}{5}(x-10)$

Convert it to the standard form:

$y+7=-\dfrac{2}{5}(x-10)$ multiply both sides by 5

$5y+35=-2(x-10)$ use the distributive property a(b + c) = ab + ac

$5y+35=(-2)(x)+(-2)(-10)$

$5y+35=-2x+20$ subtract 35 from both sides

$5y=-2x-15$ add 2x to both sides

$2x+5y=-15$
