No, because the sum of any of the sides must be greater than all sides. 5.6 +4.0=9.6 which is less than 10.6, meaning that it is impossible to create a triangle with those lengths.

3. A driver's path when diving off of a platform is given by h(t)=-5t^2+10t+20, where h(t) is the distance above water, in feet,

agasfer [191]

Answer:

3a.=20ft 3b.=1 second 3c.=3.25seconds

Step-by-step explanation:

Hello, Courtney!

h(t)=-5t^2+10t+20

20 would be the height so 3.a would be 20ft

3b. 25=-5t^2+10t+20

-5t^2+10t-5 then divide by greatest factor the answer would 1 second

3c. 0=-5t^2+10t+20 divide by greatest factor and would get 3.25 and -1.25 but can't have negative so the answer is 3.25.

I hope this helps

best you know who!

the ages of six girls are as follows;17,8,12,15,15,13 .what would be the age of the seventh girl that would make the mean age of

Elden [556K]

Answer:

11 yrs

Step-by-step explanation:

Mean = sum of ages/number of ages

Let the age of the seventh girl be A

Given the addition of the age of the seventh girl will make the mean of the ages be 13,

So,

13 = 17+8+12+15+15+13+A/7

Add up the ages

13 = 80 + A /7

Cross multiply

80 + A = 13 x 7

80 + A = 91

Subtract 80 from both sides to isolate A

80 - 80 + A = 91 - 80

A = 11

The age of the seventh girl is 11

What is the solution of the equation? 2(x+6)3−−−−−−−√5 + 3 = 19

joja [24]

Answer:

x = 10.58

Step-by-step explanation:

It seems the equation is following

$\frac{2(x+6)3}{\sqrt{5}+3}=19\\\\$

3 and 2 will simpy multiply and become 6

$\sqrt{5}+3$ will go to RHS and will multiply with 19

$6(x+6)= 19(\sqrt{5}+3)\\\\$

6(x+6) will become = 6x + 36

$6x+36 = 19\sqrt{5}+57)\\\\$

$6x = 19\sqrt{5}+57-36\\\\$

$19\sqrt{5} = 42.48$

6x = 42.48 + 21

6x = 63.48

x = 10.58
