Which of the following is a solution of x2 + 5x = −2?

adoni [48]

X^2 + 5x = -2
x^2 + 5x + 2 = 0

x = -b (+-) sqrt (b^2 - 4ac) / 2a
a = 1, b = 5, and c = 2

x = -5 (+-) sqrt (5^2 - 4(1)(2)) / 2(1)
x = -5 (+-) sqrt (25 - 8) / 2
x = -5 (+-) sqrt (17) / 2

answer is : negative 5 plus or minus the square root of 17 divided by 2

the volume of the a sphere whoes diameter is 18 cm is cubic cm . if it's diameter were reduced by half, it's volume would be of

FrozenT [24]

Answer:

The new volume is 8 times smaller than the original volume

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x ----> the volume of the reduced sphere

y ----> the volume of the original sphere

$z^{3}=\frac{x}{y}$

we have

$z=1/2$ ----> scale factor

substitute

$(1/2)^{3}=\frac{x}{y}$

$(1/8)=\frac{x}{y}$

$x=\frac{y}{8}$

therefore

The new volume is 8 times smaller than the original volume

Verify

The volume of the original sphere is

$r=18/2=9\ cm$ ---> the radius is half the diameter

$V=\frac{4}{3}\pi (9)^{3}=972\pi \ cm^{3}$

the volume of the reduced sphere is

$r=9/2=4.5\ cm$ ---> the radius is half the diameter

$V=\frac{4}{3}\pi (4.5)^{3}=121.5\pi \ cm^{3}$

Divide the volumes

$972\pi \ cm^{3}/121.5\pi \ cm^{3}=8$

A rectangle is 12 feet long and 34 feet wide. What is the area of the rectangle? Enter your answer in the box as a fraction in s

guajiro [1.7K]

The rectangle is 48 feet long. To find area just take the lenght, and the width and multiply them. In this case the length is 12 feet, and the width is 34 feet. So 12 x 34 = 48 ft.
