x,y, and z to the nearest tenth .(hint: use altitude and leg rules) PLEASE HELP FAST !!! please solve and show steps
madreJ [45]

Use the Pythagorean theorem to find z:

z = √(6^2 + 9^2)

z= √(36 + 81)

z = √117

z = 3√13 = 10.8

Use leg rule to find x:

x/6 = 6/9

Cross multiply:

9x = 36

Divide both sides by 9:

x = 36/9

x = 4

Use Pythagorean theorem to find y:

y = √(6^2 + 4^2)

y= √(36 + 16)

y = √52

y = 2√13 = 7.2

4. 1 less than twice the square of a number
givi [52]

Answer:

2(x^2)-1

Step-by-step explanation:

The square of a number is just the number squared. We don't know what the number is so I will just say it is x. So we have 2 times x^2. Then we have to minus 1 from that. So 2(x^2)-1.

Hope this helps! :D

Eva deposited $30 in a savings account earning 10% interest, compounded annually.
alexdok [17]

Answer:

$ 9

Step-by-step explanation:

Simple Interest = P.R.T / 100

P = Principal (Amount invested) =$30

R = Rate= 10%

T = Time = 3 years

Therefore, Simple Interest (I):

I = PRT/100

I = ($30 * 10 * 3 ) / 100

I = $900 / 100

I = $9

She will have a total of $9 in three years
