Answer:

15.65 foot

Step-by-step explanation:

Pythagoras theorem can be used

a² + b² = c²

a being 14
b being unknown ( x )
c being 21

hence,

14² + x² = 21²
196 + x² = 441

x = √245  

  = 15.65 foot (answer)

Write an equation of the line that passes through the given points.<br> (-2,8) and (1, -1)
KIM [24]

/Answer:

Short Answer Type:

P1 - (-2,8)

P2 - (1,1)

Slope: (1 - 8) / (1 + 2)

=> -7/3

Therefore: 1 = -7/3 + c

=> 10/3 = c

<h2><u>Therefore equation: y = -7x/3 + 10/3</u> </h2>

Fantom [35]

In linear equation, 15.2% did the total number of students on the honor roll decrease.

What in mathematics is a linear equation?

  • A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
  • Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

50 × 24% = 12

50 × 14%= 7

12+ 7 = 19

50+75 = 125

19 ÷125= 15.2%

A cone has a height of 2.5 in. and a radius of 5 in. What is the volume of the cone? (Use 3.14 for Pi. Round the answer to two d
Stells [14]

Answer:

V =\frac{1}{3} \pi r^2 h

And replacing we got:

V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3

And the best option would be:

65.42 Inches cubed

Step-by-step explanation:

For this case we have the following info given:

h =2.5 in represent the height of the cone

r = 5 in represent the radius

And the volume of the cone is given by;

V =\frac{1}{3} \pi r^2 h

And replacing we got:

V = \frac{1}{3} (3.14) (5in)^2 (2.5in) = 65.42 in^3

And the best option would be:

65.42 Inches cubed
