Help me please, need this done now.

Nikolay [14]

simplifying $\frac{\sqrt{4}}{\sqrt[3]{4}}$ we get $4^{\frac{1}{6}}$

Option B is correct.

Step-by-step explanation:

We need to simplify: $\frac{\sqrt{4}}{\sqrt[3]{4}}$

Solving:

$\frac{\sqrt{4}}{\sqrt[3]{4}}$

We know that √ = 1/2 and ∛=1/3

$\frac{4^{\frac{1}{2}}}{4^{\frac{1}{3}}}$

Applying exponent rule: $\frac{x^a}{x^b}=x^{a-b}$

$=4^{\frac{1}{2}-\frac{1}{3}}\\=4^{\frac{3-2}{6}}\\=4^{\frac{1}{6}}$

So, simplifying $\frac{\sqrt{4}}{\sqrt[3]{4}}$ we get $4^{\frac{1}{6}}$

Option B is correct.

Find the radius r of the sphere.

AleksandrR [38]

Given:

The volume of the sphere = 12348π in³

To find the radius of the sphere.

Formula

The volume of a sphere of radius r is

$V = \frac{4}{3} \pi r^{3}$

According to the problem,

$\frac{4}{3} \pi r^{3} = 12348\pi$

Eliminating π from both the side.

or, $\frac{4}{3} r^{3}= 12348$

or, $r^{3}=\frac{(12348)(3)}{4}$

or, $r^{3}=9641$

or, $r=\sqrt[3]{9261}$

or, $r=21$

Hence,

The radius of the sphere is 21 inches.

Write the standard equation of the circle if the center is (-1,2), and a point on the circle is (2,6).

ladessa [460]

Answer:

(x + 1)² + (y - 2)² = 25

Step-by-step explanation:

The center is given:

(-1, 2)

Find the radius, the distance from the center to a point (2, 6)

r² = (2 - (-1))² + (6 - 2)² = 3² + 4² = 25
r = √25 = 5

Use circle formula:

(x - h)² + (y - k)² = r²
(x - (-1))² + (y - 2)² = 5²
(x + 1)² + (y - 2)² = 25

Please tell me how to solve this i just started geometry as a freshman and i don’t understand please!!!

aliya0001 [1]

Answer:

80 degrees

Step-by-step explanation:

The whole angle EBD is 115 degrees, and angle DBG is 35 degrees, therefore

angle GBE is 115-35=80 degrees

Think about it like this, DBG and GBE need to add up to the angle measure of EBD, in other words 35 + GBE = 115
