Answer:

[tex] \huge \purple{\therefore \cos2a} \orange{= }\red{\frac{7}{25} } [/tex]

Step-by-step explanation:

[tex] \because \cos2a =1 - 2 { \sin}^{2} a \\ \\ \therefore \cos2a =1 - 2 \bigg( { \frac{3}{5} }\bigg) ^{2} \\ \\\therefore \cos2a =1 - 2 \times \frac{9}{25} \\ \\\therefore \cos2a =1 - \frac{18}{25} \\ \\\therefore \cos2a = \frac{25 - 18}{25} \\ \\ \huge \purple{\therefore \cos2a} \orange{= }\red{\frac{7}{25} } \\ \\[/tex]

Answer: -5 - (-10 )= 5

Step-by-step explanation:

 The arrows on the number line stops at -5 and -10 so you subtract -5 minus -10 and get your anwser 5

Answer:

Driver B

Step-by-step explanation:

From the given options, Driver B will win the next race because the previous result shows that Driver B has the fastest race time due to the fact that it recorded the lowest mean race time.

Similarly, the standard deviation of 0.12 seconds illustrates that the driver keep-up with the bearest minimum time frame all through the entire race time.

Answer:

It is B and the other one is Driver C if you have that question

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

So the square root of 21 is 4.582...

If you round 4.582.. it is 5

Because you look at the first number behind the decimal (tenths place) if it is 4-0 you leave the number the same. If it is 5-9 you increase the number by 1.

Hope this helps ya!!

Answer:

Step-by-step explanation:

Bisect means in half so both angles equal each other, meaning the equations equal each other.

2x+7 = 4x-9

Subtract 4x from both sides

-2x+7 = -9

Subtract 7 from both sides

-2x = -16

x = 8, so the answer is the third choice

Bisect means in half so both angles equal each other, meaning the equations equal each other.

2x+7 = 4x-9

Subtract 4x from both sides

-2x+7 = -9

Subtract 7 from both sides

-2x = -16

x = 8, so the answer is the third choice

Answer:

9x-9

Step-by-step explanation:

9 and a product of a number is 9x, and less 9 is 9x-9.

Answer:

true

Step-by-step explanation:

Answer:

Step-by-step explanation:

We will use the following steps to solve this problem,

Step - (1).

Covert the equations into slope-intercept form.

Step - (2)

If the slopes of the two lines are equal, lines will be parallel.

[tex]m_1=m_2[/tex]

Step - (3)

If the slopes of the two lines are negative reciprocal, lines will be perpendicular.

[tex]m_1\times m_2=-1[/tex]

Line 1: 8x - 6y = -2

          6y = 8x +2

            y = [tex]\frac{4}{3}x+\frac{1}{3}[/tex]

Slope of line 1 = [tex]m_1=\frac{4}{3}[/tex]

Line 2: y = [tex]-\frac{3}{4}x-5[/tex]

Slope of line 2 = [tex]m_2=-\frac{3}{4}[/tex]

Line 3: 4y = -3x + 3

             y = [tex]-\frac{3}{4}x+\frac{3}{4}[/tex]

Slope of line 3 = [tex]m_3=-\frac{3}{4}[/tex]

1). Since, [tex]m_1\times m_2=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]

   Line 1 and line 2 are perpendicular.

2). Since, [tex]m_1\times m_3=\frac{4}{3}\times (-\frac{3}{4})=-1[/tex]

   Line 1 and line 2 are perpendicular.

3). Since, [tex]m_2=m_3=-\frac{3}{4}[/tex]

   Line 2 and line 3 are parallel.

Step-by-step explanation:

You plug g(3) into the equation like this

g(3) = -x - 2

Answer:

Slope is 100

y-intercept is 85

Step-by-step explanation:

The equation of a straight line can be modeled according to the function;

y = mx + c

where m is the slope and c is the y-intercept

comparing what we have ;

y = 100x + 85 with the standard form ;

Slope will be 100 and y-intercept is 85

Answer:

[tex]15\frac{8}{9}[/tex]  < 5b

Step-by-step explanation:

       15 8/9 less than the product of 5 and a number b ​

 Product of 5 and a number b;

      5 x b  = 5b

Now,

     [tex]15\frac{8}{9}[/tex]  less than

       [tex]15\frac{8}{9}[/tex]  < 5b

The algebraic expression is  [tex]15\frac{8}{9}[/tex]  < 5b

When a number is less than another, the other number is greater.

Answer: z=6

Step-by-step explanation:

4(z-3)=2z

4z-12=2z subtract 2z from both sides

2z-12=0 add 12 to both sides

2z=12 divide 2 to both sides

z=6

Answer:

Choice D

Step-by-step explanation:

When you convert a unit to a smaller unit it will always get bigger so in this case you will move the decimal point to the right so 21.5 will become 215.

Answer:

x = 16

DISREGARD 16.5 MY BAD the answer is 16

Step-by-step explanation:

140 = 8x+12

Subtract 12 on both sides

128 = 8x

Divide by 8

16 = x

x = 16

Answer:

x = 16

Step-by-step explanation:

(8x + 12)° = 140°

8x + 12 = 140

8x = 128

x = 128 ÷ 8

x = 16
