Answer:

176/317

Step-by-step explanation:

The formula for slope is [tex]\frac{y2 - y1}{x2 - x1}[/tex], which means you have to subtract the second point's y coordinate (286) minus the first point's y coordinate (110).

Now you have [tex]\frac{286-110}{x2 - x1}[/tex] or [tex]\frac{176}{x2 - x1}[/tex].

Now you have to do the same for x.

446 - 129 = 317, which gives you the final answer of

[tex]\frac{176}{317}[/tex], or about 0.555.

Answer:

1,044cm

Step-by-step explanation:

46-21=25cm (the length of the top line)

30-14=16cm (the length of the other line on the left of the 21)

Split it into three rectangles, 25×16, 21×14 and 25×14

25×16 = 400cm

21×14 = 294cm

25×14 = 350cm

Add to together: 400+350+294= 1044cm

Answer:

-1

Step-by-step explanation:

The slope is the change in the Y value divided by the change in the X value. Therefore, the slope of this line is:

(-17-[-18])/(-7-[-6) = (-17+18)/(-7+6) = (1)/(-1) = -1

Answer:

2: 125

4: 55

7: 125

3: 125

Step-by-step explanation:

Since the top and bottom lines are parallel, 2 is equal to 6.

since angles 4+2 sums up to a straight line, its 180 degrees

125+55 is 180

same with 3, 3+4 is 180

7 is same as 3

180

Step-by-step explanation:

9:40

?:800

9×20=180

40×20=800

it is a ratio. 9 oranges to 40 people. 40 times 20 is 800 so you do the same to 9 (which gives you 180)

Answer:

180/800

Answer:

Slope : 1, Intercept- 3, equation: y = 1x + 3

Step-by-step explanation:

slope is the change of rate and it can be observed that the rate of change from each square is 1

y intercept is the spot where the line intersects with the y axis

equation format: y = mx + b where mx is slope and b is the y intercept

Answer:

Height - 12.692 in

Step-by-step explanation:

Answer:

A = 1/2 bh

Step-by-step explanation:

Replace are and base to get:

82.5 = 1/2 x 15 x height

Multiply both sides by 2:

165 = 15 x height

Divide both sides by 15:

Height = 165 / 15

Height = 11 inches.

Answer:

2cis(20°)

Step-by-step explanation:

we are given that

[tex] \displaystyle \rm z = 10cis ({30}^{ \circ} )[/tex]

[tex] \displaystyle \rm w = 5cis ({10}^{ \circ} )[/tex]

We want to find z/w . To do so, divide 10cis(30°) by w = 5cis(10°) which yields:

[tex] \displaystyle \rm \frac{ z}{w} = \frac{10cis ({30}^{ \circ} )}{5cis( {10}^{ \circ} )}[/tex]

recall that,

[tex] \displaystyle \rm \frac{ r_{1} cis ({ { \theta}_{1}} )}{ r_{2}cis( { \theta}_{2})} = \frac{ r_{1} }{ r_{2} } cis({ \theta}_{1} - { \theta}_{2})[/tex]

consider,

Therefore, utilizing the formula yields:

[tex] \displaystyle \rm \frac{ z}{w} = \frac{10cis ({30}^{ \circ} )}{5cis( {10}^{ \circ} )} \\ \implies \rm\frac{ z}{w} = \dfrac{10}{5} cis( {30}^{ \circ} - {10}^{ \circ} ) \\ \implies \rm \dfrac{z}{w} = \boxed{ \rm2cis( {20}^{ \circ} )}[/tex]

and we're done!

NB: cis(x) is also known as cos(x)+i×sin(x)

Answer:

19+4i

Step-by-step explanation:

Multiply using the FOIL method, then combine the real and imaginary parts of the expression.

FOIL

A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial, Outer means multiply the outermost terms in the product, Inner means multiply the innermost terms, and Last means multiply the terms which occur last in each binomial.

Result of multiplication of complex numbers will be 19 + 4i

Given,

(3 + 2i)(5 – 2i)

Here,

Complex numbers standard form : x ± iy

Here,

x = real part

y = complex part.

i = iota = [tex]\sqrt{-1}[/tex]

So,

Multiplication :  (3 + 2i)(5 – 2i)

⇒15 -6i + 10i -4i²

Here,

i = √-1

i² = -1

So,

15 -6i + 10i -4i²

15 -6i + 10i - 4(-1)

⇒19 + 4i

Answer:

Step-by-step explanation:

Use the distributive property to eliminate parentheses. Use the properties of arithmetic to combine the numbers.

The order of operations tells you to start with the inner parentheses and work outward.

  [tex]-\dfrac{1}{3}(6(p+q)-3(p-2(p-3q)))=-\dfrac{1}{3}(6(p+q)-3(p+(-2)(p) +(-2)(-3q)))\\\\=-\dfrac{1}{3}(6(p+q)-3(p-2p+6q))=-\dfrac{1}{3}(6(p+q)-3(-p+6q))\\\\=-\dfrac{1}{3}((6)(p)+(6)(q)+(-3)(-p)+(-3)(6q))=-\dfrac{1}{3}(6p+6q+3p-18q)\\\\=-\dfrac{1}{3}(9p -12q)=(-\dfrac{9p}{3})+(-\dfrac{-12q}{3})=\boxed{-3p+4q}[/tex]

Answer:

B = 21.4°

Step-by-step explanation:

Using the Law of Sines.

[tex]sin(42)/22=sin(B)/12[/tex]

Cross Multiply

[tex]12*sin(42)=22sin(B)[/tex]

Get Sin(B) by itself.

sin(B)= 12*sin(42°) / 22

B° = sin^-1((12*sin(42°))/22)

B = 21.4°

Answer:

V = 2143.573333333333.... in³

Step-by-step explanation:

Formula for volume -> V = 4/3 πr³

We know the circumverence now we need to et the radius.

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

Divide the diameter by 2.

There you go, you found the circle's radius.

16pi/pi = 16/2 = 8

V=4/3πr³

V=4/3π8³ = 2143.5733333333333333333333333333333333333333333333333333333333333...
