Answer:

x + 2 < 42

Step-by-step explanation:

Minimum height for Crazy cart = 42 inches

x = height last summer

Number if inches grown since last summer = 2

Height now = x + 2 is still not yet up to 42 inches because he is not yet tall enough to get on crazy carts ride.

Representing as an inequality :

x + 2 < 42

A ball is kicked into the air and follows the path described by h(t)= – 4.9t^2 + 6t + 0.6, where t is the time in seconds and h
miv72 [106K]
The maximum value can be determined by taking the derivative of the function.

(dh/dt) [h(t)] = h'(x) = -9.8t + 6

Set h'(x) = 0 to find the critical point

-9.8t + 6 = 0
-9.8t = -6
t = 6/9.8

Plug the time back into the function to find the height.

h(6/9.8) = -4.9(6/9.8)^2 + 6(6/9.8) + .6
= 2.4

And I don't understand your second question.

104 = -16T2 + 729

16t^2 =  729 - 104 = 625

4t = +/-25

t = +/-6.25

Between 6.25 and 13.5 seconds after he jumps

what is the measure of the base angle,x, of the isosceles triangle shown below? round your answer to the nearest tenth of a degr
MAVERICK [17]

Answer:

x ≈ 49.7°

Step-by-step explanation:

Since, the given triangle is an isosceles triangle,

Two sides having measure 17 units are equal.

Opposite angles of these equal sides will be equal.

Measure of the third angle = 180° - (x + x)°

By sine rule,

\frac{\text{sinx}}{17}=\frac{\text{sin}(180-2x)}{22}

\frac{\text{sinx}}{17}=\frac{\text{sin}(2x)}{22} [Since, sin(180 - θ) = sinθ]

\frac{\text{sinx}}{17}=\frac{2(\text{sin}x)(\text{cos}x)}{22}

\frac{\text{sinx}}{17}=\frac{(\text{sin}x)(\text{cos}x)}{11}

\frac{1}{17}=\frac{(\text{cos}x)}{11}

cos(x) = \frac{11}{17}

x = 49.68°

x ≈ 49.7°
