Mathematics

IrinaK [193]3 years ago

Answer:

<h2>m = 21, b = 5 → y = 21x + 5</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept → (0, b)</em>

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

=====================================

From the table we have y-intercept (0, 5) → <em>b = 5 </em>and other point (1, 26).

Calculate the slope:

m=\dfrac{26-5}{1-0}=\dfrac{21}{1}=21

What is the volume of the square pyramid shown below?
vfiekz [6]
The volume of a square pyramid is given by the following formula:

V = a^{2} \frac{h}{3}

a is the side length of the square base, and h is the height of the pyramid.

Plug in your known values into the formula:

a = 9, h = 5
V = 9^{2} \times \frac{5}{3}
V = 81 \times \frac{5}{3}
V = 135

The volume of this square pyramid is 135 centimeters cubed.

Give the diagram shown at the right, find the value of 3x.<br><br><br> Pls help!!
EastWind [94]

Answer:

<h2>3x = 18</h2>

Step-by-step explanation:

Use the Pythagorean Theorem here:

30² = (3x)² + (4x)², or:

30² = 9x² + 16x²  =  25x²

Taking the square root of both sides, we get √(30)² = √(25x²), or:

30 = ± 5x

Neglect -5x, since we are measuring distances, and distances are positive.

Then 5x = 30, and so x = 6

Thus, 3x = 3(6) = 18

Mila [183]

Answer:

A=38.88 or 38.9

Step-by-step explanation:

If both are similar then the 9 and the 7.2 are the same

9-7.2= 1.8

9x6=54

7.2-1.8=5.4

7.2x5.4=38.88 or 38.9
