sweet [91]

Answer:

(y + z)(y + 4z)

Step-by-step explanation:

${y}^{2} + 5zy + 4 {z}^{2} \\ = {y}^{2} + zy + 4zy + 4 {z}^{2} \\ = y(y + z) + 4z(y + z) \\ = (y + z)(y + 4z)$

The area of a triangle is 528cm2. The length of its base is 33cm. Calculate the perpendicular height of the triangle

IRISSAK [1]

A = bh/2
A = 33 x h / 2
528 = 33h / 2
33h = 1056
h = 32cm

Can someone solve Pythagorean theorem

Ad libitum [116K]

Answer:

48 units

b= 48 units

Step-by-step explanation:

pythag is $a^2+b^2=c^2$

we have a and c

so substitute them in

$14^2+b^2=50^2$

now you can solve

$196+b^2=2500$

subtract 196 from both sides

$b^2=2500-196$

subtract

2500 - 196 = 2304

$b^2=2304$

solve for the square root

square root of 2304= 48

therefore b= 48 units

1. Determine the measure of the unknown angles indicated by letters. Justify your answers with

Maurinko [17]

Answer:

hello,

Step-by-step explanation:

In an isocele triangle, base's angles have the measure:

42+2a=180

2a=180-42

a=69(°)

in a triangle, an external angle has for measure the sum of the angles not adjacents.

55+b=132

b=77 (°)

in a quadrilater the sum of the (interior) angles is 2*180=360 degrees.

90+90+68+c=360

c=360-90-90-68

c=112 (°)

A spherical balloon is being inflated at a rate of 3 cubic inches per second. Determine the change in the rate of the radius.How

Novay_Z [31]

Answer:

The rate rate of change of radius is $\frac{1}{48\pi}$ inches per second when the diameter is 12 inches.

The radius is changing more rapidly when the diameter is 12 inches.

Step-by-step explanation:

Consider the provided information.

A spherical balloon is being inflated at a rate of 3 cubic inches per second.

The volume of sphere is $V=\frac{4}{3}\pi r^3$

Differentiate the above formula with respect to time.

$\frac{dV}{dt}=4\pi r^2\frac{dr}{dt}$

Substitute the respective values in the above formula,

$3=4\pi 6^2\frac{dr}{dt}$

$\frac{1}{48\pi}=\frac{dr}{dt}$

The rate rate of change of radius is $\frac{1}{48\pi}$ inches per second when the diameter is 12 inches.

When d=16

$3=4\pi 8^2\frac{dr}{dt}$

$\frac{3}{256\pi}=\frac{dr}{dt}$

Thus, the radius is changing more rapidly when the diameter is 12 inches.
