Step-by-step explanation:

Answer:

m (Slope) = 3

Step-by-step explanation:

Slope formula:

m = (y2 - y1) / (x2 - x1)

= (24 - 3) / (9 -2)

= 21 / 7

Answer:

n+11=15

  -11 -11

n=4

Step-by-step explanation:

subtract 11 from both sides

Answer:

-11 -11

n=4

Step-by-step explanation:

subtract on both sides

-11

you get left with n=4

x= 1 + 5 √2

x= 1 - 5 √2

The values of x in the expression are x = 1 + √51 and x = 1 – √51.

We have,

Expanding the left side of the equation, we get:

(x – 1)2 = x2 – 2x + 1

So, we have:

x2 – 2x + 1 = 50

Subtracting 50 from both sides, we get:

x2 – 2x – 49 = 0

Now, we can use the quadratic formula to solve for x:

x = [2 ± √(22 – 4(1)(–49))] / (2)

x = [2 ± √(204)] / (2)

x = [2 ± 2√51] / (2)

x = 1 ± √51

Therefore,

The values of x are x = 1 + √51 and x = 1 – √51.

Answer:

1. The radius is 90 ft.

2. 31.4 cm.

Step-by-step explanation:

1. The way to find the radius with just the diameter, is to divide by two.

2. When finding circumference, you need to multiply the diameter by 3.14 (pi), making it 10 x 3.14.

Answer:

The radius is 90

Step-by-step explanation:

the line in the middle of the circle is the diameter so in order to find the radius you need to find half of the diameter. Half of the diameter (180) is 90 90 the radius is 90.

Answer: x=64°

Step-by-step explanation:

According to the diagram, the two intersecting lines are perpendicular. That means each part is 90°. Since the left side is labelled to be 180°, we know that the sum of the right side is also 180°.

26+x+90=180            [combine like terms]

116+x=180                  [subtract both sides by 116]      

x=64°

Now, we know that x=64°.

On the other hand, we can see that 26+x=90. We can also use that to solve for x.

26+x=90                    [subtract both sides by 26]

x=64°

Step-by-step explanation:

3,000 - 988 + 748 - 885 + 1,099 = 2,974

Answer:

See below.

Step-by-step explanation:

We have:

[tex]\frac{\sqrt3}{\sin(\theta)}=2[/tex]

And we want to find two different angles between 0 and 180 that satisfy this equation.

First, let's get our sine out of the denominator. Notice that this is the same as:

[tex]\frac{\sqrt3}{\sin(\theta)}=\frac{2}{1}[/tex]

Cross-multiply:

[tex]2\sin(\theta)=\sqrt{3}[/tex]

Divide both sides by 2:

[tex]\sin(\theta)=\frac{\sqrt{3}}{2}[/tex]

Here you go! I'll have the answer for you if you scroll down, so check it when you're ready!

#2 is correct. However, double check #3. The answer's down there too... :)

[Blank space...]

[More blank space...]

[And more...]

Answer for 1)

We have:

[tex]\sin(\theta)=\sqrt{3}/2[/tex]

So, at what points between 0 and 180 does sine equal √3/2?

If we refer to the unit circle, we can see that this happens twice: at 60.

Thus, the second time it occurs will be at 180-60 or 120.

So:

[tex]\theta=60\textdegree\text{ or } 120\textdegree[/tex]

Answer for 3)

So you are correct for the first three. So:

[tex]\sin(54)=t[/tex]

However, sine stays positive. So, our angle must be between 0 and 180.

So, instead of 180+54, it should be 180-54, giving us:

[tex]\sin(54)=\sin(126)=t[/tex]

Answer:

the answer is y= -4

Step-by-step explanation:

in this you basically just isolate the variable which means that you get rid off all the numbers that are applied to the varible by preforming the opposite opperation. In this case if you subtract 2 from both sides, the 2 on the left gets cancelled out and the -2 on the right turns into -4, so your equation would look like y=-4

Answer:

b = (4/6) - a/2

Step-by-step explanation:

6b + 3a = 4

6b = 4 - 3a

b. = (4 - 3a)/6

b. = (4/6) - a/2

The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

It is defined as the combination of constants and variables with mathematical operators.

In the provided expression, variable and constant are there

It is given that:

The equation in a and b, where a and b are the variables:

3a + 6b = 4

Here the indicated variable is b.

To find the value of b in terms of a make the subject as b:

Subtract 3a on both the sides in the equation 3a + 6b = 4:

The equation becomes:

3a + 6b -3a = 4 - 3a

6b = 4 - 3a

Divide by 6 on both sides:

The equation becomes:

6b/6 = (4 - 3a)/6

b = (4 - 3a)/6

Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

Answer: (1) -3/4   (2) 7     (3) y = (-3/4)x + 7     (4) 1/2

Step-by-step explanation:

1) COUNT the number of spaces from one point to the other point.

   from (0, 7) to (4, 4) is: down 3 and right 4   →   m = -3/4

2) the y-intercept is where the line crosses the y-axis (when x = 0).

   The line crosses the y-axis at (0, 7)    →   b = 7    

3) Slope-Intercept form is y = mx + b

   m = -3/4  and b = 7     →      y = (-3/4)x + 7

4)  COUNT the number of spaces from one point to the other point.

 from (-2, -4) to (2, -2) is: up 2 and right 4   →   m = 2/4  = 1/2 when simplified
