Answer:

Approach: Difference of Squares Pattern

$4 {x}^{2} - 25 = (2x - 5)(2x + 5)$

Step-by-step explanation:

The given binomial is:

$4 {x}^{2} - 25$

We can rewrite to obtain:

${(2x)}^{2} - {5}^{2}$

This is a difference of two squares, so we will factor using difference of squares pattern.

Recall that:

${a}^{2} - {b}^{2} = (a + b)(a - )$

If we let

$a = 2x$

and

$b = 5$

Then we can factor the given binomial to obtain:

${2x}^2 - {5}^{2} = (2x - 5)(2x + 5)$

$\therefore4 {x}^{2} - 25 = (2x - 5)(2x + 5)$

The volume of a sphere is a function of its radius, V=4/3(pie)(r^3). Evaluate the function for the volume of a volleyball with

Travka [436]

Volume of a volleyball (a sphere) = 4/3πr³
= 4/3π(11.4)³
= 1975.392π
= 6210 cm³ (to 3 significant figures)

The volume of a volleyball with a radius of 11.4 cm will be 6210 cm³.

Help me pls, BRAINEST AWARD

Natali [406]

Answer:

x = 3.7

Step-by-step explanation:

By applying sine ratio for the given angle B,

sin(39°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

sin(39°) = $\frac{AD}{AB}$

0.6293 = $\frac{AD}{7}$

AD = 4.41

By applying tangent ratio for the given angle C,

tan(50°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

1.19 = $\frac{AD}{x}$

1.19 = $\frac{4.41}{x}$

x = 3.7
