The volume of the cylinder is 31.4 in³.

The volume can be calculated with the following formula:

V= $\pi$ r²h

V= $\pi$ ×1² in×10 in

V= $\pi$ ×10 in²

V≈31.4 in³

In an arithmetic sequence, T1=4 and T7=22.

jonny [76]

Answer:

Step-by-step explanation:

t1 means a1 and t7 means a7

a+(n-1)d=an

a+(1-1)d=4

so we get a as 4

a=4

a+(n-1)d=an

4+(7-1)d=22

4+6d=22

6d=22-4

d=18/6

d=3

Write the number 0.21212121…. as a fraction.

vekshin1

100x = 21.212121.....

100x - x = 21.212121... – 0.212121...

99x = 21. ( divide both side by 90)

x = 21/99

x = 21:3/99:3

x = 7/33

Answer:

$Slope (m) = \frac{y}{x} = \frac{3}{1} =3$

Step-by-step explanation:

$Slope (m) = \frac{y}{x} = \frac{3}{1} =3$

$0 = arctan(\frac{y}{x}) + 180^o = 251.56505117708^o$

X = -4 – -2 = -2

Y = 4 – 10 = -6

$Distance (d) = \sqrt{x^2+y^2}=\sqrt{40} = 6.3245553203368$

Equation of the line:

y = 3x + 16

When x=0, y = 16

When y=0, x = -5.3333333333333

a vector has a magnitude of 50 in the 35º direction. what are the horizontal and vertical components of this vector?

Semenov [28]

Answer:

Horizontal component: 40.95

Vertical component: 28.67

Step-by-step explanation:

To find the horizontal and the vertical component of this vector, you need:

The formula for calculate the horizontal component:

$a_x=|a|cos\alpha$

Where $|a|$ is the magnitude

The formula for calculate the vertical component:

$a_y=|a|sin\alpha$

Where $|a|$ is the magnitude

Given the angle 35 degrees and the magnitude,you can substitute values into the formulas.

Therefore, you get that the horizontal component and the vertical component of this vector are:

$a_x=50cos(35\°)=40.95$

$a_y=50sin(35\°)=28.67$
