Answer:

no idea so sorry

Step-by-step explanation:

Because sine and cosine are complements, we will have that:

cos(60°) = 1/2.

First, because cosine and sine are complements, we know that:

cos(x) = sin(x + 90°).

cos(90° - x) = sin(x).

We will use the second relation, with x = 30° we can write:

cos(90° - 30°) = sin(30°)

cos(60°) = sin(30°)

And we know that sin(30°) = 1/2

Then we also have cos(60°) = 1/2.

So the correct option is d.

Step-by-step explanation:

I plugged the table into Desmos and I determined the slope and intercept from that.

Answer: The slope is 2.

Step-by-step explanation:

To get the slope, use this tip: Rise over run

Count how much it rises, which is 4, and how much it "runs' which is 2. Now put rise above run which is 4/2. This simplifies to simply 2.

Answer:

The slope is 2.

Step-by-step explanation:

The points on the line are (1, -2) which can be labeled as x1 and y1, and the other is (3,2) which can be labeled as x2 and y2. you set up the equation in the slope formula, so 2 - - 2 / 3 - 1. Since there are two negatives, the subtraction signs turn into addition signs, and you get 4/2, which simplyfied is 2. Hope this helps :)

Answer:

Step-by-step explanation:

Since x=-4 plug in the -4 into the equation to find y,

-5(-4)-4y=16

20-4y=16                                                                                                                             -20       -20                                                                                                                   __________

-4y=-4

-4y/-4=-4/-4

___________

y=1

So now you found both x and y so plug in both now to check if both are correct.

-5(-4)-4(1)=16

20-4=16

16=16

So both y and x are correct.

Hope this helps!:)

Answer:

3x-5=7

3x=7+5

x=12/3

x = 4

Answer:

Step-by-step explanation:

3 times a number x: 3*x = 3x

5 subtracted from  3x = 3x - 5

Equation: 3x - 5 = 7

Solution:

    Add 5 to both sides

3x - 5 + 5 = 7 + 5

         3x = 12

Divide both sides by 3

        3x/3 = 12/3

x = 4

V = 785.7ft³

Step-by-step explanation:

V = π r² h

V = 22/7 (5) 10

V = 22/7 × 25 ×10

V = 22/7 × 250

V = 22 × 250 ÷ 7

V = 550 ÷ 7

Answer:

115 degrees

Step-by-step explanation:

We know that angle y is 45 degrees and angle z is 70 degrees so to find x, you do 180-45-70 to get 65 degrees.

Because W plus X has to equal 180 degrees, 180-65=115, so the answer is 115 degrees

Answer:

choice 3) W = 115 degrees

Step-by-step explanation:

all triangle interior angles add up to 180 degrees

180 = 45 + 70 + X

X = 65 degrees

Angle W is supplemental to angle X (angle W and angle X add up to 180 degrees.)

W = 180 - 65 = 115 degrees

Answer:

3/4 is less than 7.

Step-by-step explanation:

There are 4 numbers but there are only 3 less than 7.

The probability P(less than 7) is 3/4.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

For the given situation,

The cards are numbered as s = {4,5,6,7}

⇒[tex]n(s)=4[/tex]

The event is probability of picking the cards less than 7

Cards less than [tex]7[/tex] ,  [tex]e=4,5,6[/tex]

⇒[tex]n(e)=3[/tex]

Probability of picking the card is given by [tex]p(e)=\frac{n(e)}{n(s)}[/tex]

On substituting the values,

⇒[tex]p(less than 7)=\frac{3}{4}[/tex]

Thus the probability P(less than 7)  is 3/4.
