Answer:

Step-by-step explanation:

You have so many questions here that doing one or two of them will hardly matter since are many more present.

Pick number 3 to start with

The left and right part of the cross will contain two numbers that multiply to 16. The numbers should be 8 and 2. Are 8 and 2 the right answers. ? They should be, because the bottom part of the cross is 8 and 2 added which is 10.

So the answer is left is 8, right is 2, bottom is 10. The 8 and 2 can be switched.

Try number nine next.

You need two numbers that multiply to 72 and that add to 18. You could use 8 and 9, but they done work. They do multiply to 72 but they only add to 17 which is not good enough.

Try 12 and 6. That looks much better. 12 * 6 does multiply to 72 so we're good so far. But the clincher is that 12 and 6 add to 18 which makes the answer right.

bottom = 12 + 6

left = 12

right = 6

Top = 12*6 = 72

Note: do all the ones that have no minus signs. When you have done that, come back and ask how to do a question that has a minus.

The measure of the vertex angle of an isoceles triangle is one- fourth that of a base angle
horsena [70]

Answer:

Base angle = 72

Vertex angle = 18

Step-by-step explanation:

Measure of the base angle = x. But there are two of them. (Definition of isosceles).  Keep that in mind.

The vertex angle is 1/4 of one of the base angles. That means that the vertex is 1/4 x

All three angles = 180 degrees.

So we have x + x + x/4 = 180 degrees.

change 1/4x to 0.25x x since 1/4 = 0.25

Equation

x + x + 0.25 = 180

2.5x  = 180

Solution

2.5x = 180                      Divide by 2.5 on both sides

2.5x/2.5 = 180/2.5

x = 72

Answer

That means that each base angle = 72 degrees

The Vertex Angle = 72/4 = 18

Cassie's broker charges her a commission of $4.25 for every ten shares of stock bought or sold. Cassie buys 92 shares of Hyren A
olya-2409 [2.1K]

Answer:

2,850

Step-by-step explanation:

4.25 x 9 = 38.25

4.25 x 13 = 55.25

4.25 x 12 = 51

13.70 x 92 = 1260.4

3.28 x 130 = 426.4

8.06 x 126 = 1015.56

all totals would equal 2,846.86, which to the nearest would be $2,850

If sine of x equals square root of 2 over 2, what is cos(x) and tan(x)? Explain your steps in complete sentences.
kolbaska11 [484]
Sin x =  square root (2) / 2

In order for us to get for cos x and tan x, first we need to know what 
Hypotenuse, Adjacent, and Opposite sides.

sin x = opposite / hypotenuse.

adjacent = square root (hypotenuse^2 - opposite^2)
adjacent = square root (2^2 - square root(2)^2)
adjacent = square root (4 - 2)
adjacent = square root (2)

cos x = adjacent / hypotenuse
tan x = opposite / adjacent..

cos x = square root (2) / 2
tan x = square root (2) / <span>square root (2)  = 1

So, </span>cos x = square root (2) / 2 and tan x<span> = 1</span>

I need help on this.. First person to answer this correctly gets a BRANLIST​
arlik [135]

Answer: The relation is a function.

Step-by-step explanation: Since there is one value of y for every value of x in (-2,4), (3,7), (0,8), (5,8), and (1,6), this relation is a function.

I hope this helps you out!
