Answer 1

You can find this by using the pythagorean theorem.

The Pythagorean Theorem states that the squares of the legs add up to the square of the hypotenuse.

The hypotenuse is the longest side, which is opposite the right angle.

The other 2 sides are the legs.

Here, the hypotenuse is BC which is 17.

AC is one leg. We are trying to find the other leg.

So you set up the equation AB^2+ 15^2 = 17^2.

This simplifies to AB^2 + 225 = 289.

AB^2 = 64.

AB = 8.

Answer 2
C is your answer.

AC^2+AB^2=BC^2


15^2+AB^2=17^2


AB^2=17^2-15^2


AB^2=8^2


AB=8

Answer:

no

yes

Step-by-step explanation:

y < 5x - 4

1 < 5(1) - 4

1 < 1

This is not a true statement. 1 cannot be less than 1 itself so the answer is no.

7x - 4 < 28

7(0) - 4 < 28

-4 < 28

This is a true statement so the answer is yes.

tan x

Step-by-step explanation:

(tan-x)[sec(pi/2)-x] (sin-x)

We know that tan (-x) = - tan (x)  and sin (-x) = - sin (x)

-(tanx)[sec(pi/2)-x] -(sinx)

(tanx)[sec(pi/2)-x] (sinx)

Using the identity sec = 1/ cos

sec ( pi/2 -x) =1/cos ( pi /2 -x)

We know that cos (s-t)=cos (s) cos(t) + sin (s) sin (t)

1/ ( cos  pi/2  cos x + sin pi/2 sin x) = 1/(0 cos x - 1 sinx) = 1 / sinx

Replacing into the equation

Write in Slope Intercept form: x-3y=-15

Answers

Answer:  Slope = 0.667/2.000 = 0.333

 x-intercept = -15/1 = -15.00000

Step-by-step explanation: y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  x-3y+15  = 0 and calculate its properties

Notice that when x = 0 the value of y is 5/1 so this line "cuts" the y axis at y= 5.00000

 y-intercept = 15/3  =  5

When y = 0 the value of x is -15/1 Our line therefore "cuts" the x axis at x=-15.00000

 x-intercept = -15/1  = -15.00000

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 5.000 and for x=2.000, the value of y is 5.667. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.667 - 5.000 = 0.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  0.667/2.000 =  0.333

 Slope = 0.667/2.000 = 0.333

 x-intercept = -15/1 = -15.00000

Step-by-step explanation:

In this problem we are given his annual salary. meaning per year. to find how much he makes in a month, we must divide by how many months there are in a year.

there are 12 months in a year.

so, 48300/12= 4025

hope this helps!

Answer:

$4,025 is his monthly salary.

Step-by-step explanation:

Annual salary means yearly. Since there are 12 months in a year, you would just take his annual (yearly) salary and divide it by 12 in order to get his monthly salary. Thus it would be:

Answer:

d) x = 4/3

Step-by-step explanation:

Given equation,

→ -x + (3/7) = 2x - (25/7)

Now the value of x will be,

→ -x + (3/7) = 2x - (25/7)

→ -x - 2x = -(25/7) - (3/7)

→ -3x = -28/7

→ -3x = -4

→ x = -4/-3

→ [ x = 4/3 ]

Hence, the value of x is 4/3.
