Answer:

The ladder needs to be 26 ft long.

Step-by-step explanation:

So pythag is a^{2}+b^{2}=c^{2}

We have the height and distance from the window, so we need to find c

10^{2}+24^{2}=c^{2}

100+576= 676

\sqrt{676} = 26

Can anyone help me with this qu9?? its bothering me <br>explain ???
ArbitrLikvidat [17]

Answer:

Sue played 30 games

Step-by-step explanation:

Probability is typically given as a fraction or percentage where the numerator is the number of desired outcomes and the denominator is the total number of outcomes.  Since Sue's won 12 games and estimated the probability to be 0.4 or 4/10, you can set up a proportion, or equivalent ratios, to solve for the number of games she played:

\frac{gameswon}{totalgames}=\frac{12}{x}=\frac{4}{10}

Cross multiply:  4x = 120

Divide by 4:  4x/4 = 120/4

Solve for 'x':  x = 30 games

A ball is thrown into the air and its position is given by h ( t ) = − 6.3 t 2 + 53 t + 24 where h is the height of the ball in
nordsb [41]

Answer:

h'(t) = -12.6 t +53

Now we can set up the derivate equal to 0 and we have:

-12.6 t +53 = 0

And solving for t we got:

t = \frac{53}{12.6}= 4.206

For the second derivate respect the time we got:

h''(t) = -12.6

So then we can conclude that t = 4.206 is a maximum for the function.

And the corresponding height would be:

h(t=4.206) = -6.3(4.206)^2 +53*4.206+24= 135.468 ft

So the maximum occurs at t = 4.206 s and with a height of 135.468 m

Step-by-step explanation:

For this case we have the following function:

h(t) = -6.3t^2 +53 t+24

In order to maximize this function we need to take the first derivate respect the time and we have:

h'(t) = -12.6 t +53

Now we can set up the derivate equal to 0 and we have:

-12.6 t +53 = 0

And solving for t we got:

t = \frac{53}{12.6}= 4.206

For the second derivate respect the time we got:

h''(t) = -12.6

So then we can conclude that t = 4.206 is a maximum for the function.

And the corresponding height would be:

h(t=4.206) = -6.3(4.206)^2 +53*4.206+24= 135.468 ft

So the maximum occurs at t = 4.206 s and with a height of 135.468 m
