Answer: Initial height before launch

Step-by-step explanation:

Given

The equation y=-9.8t+109.7t+7.4  the height of toy rocket after t sec

when the rocket is launched, time is t=0

Substituting 0 for t in the equation

\Rightarrow y(0)=-9.8(0)+109.7(0)+7.4\\\Rightarrow y(0)=7.4

Here, 7.4 represents that rocket is already at a height of 7.4 m before the launch.

<h3>Answer:</h3>

4) ÷10

5) Yes

<h3>Step-by-step explanation:</h3>

<em>Question 4</em><em>:</em>

Just take the first number 322 and plug in the choices.

At the end the only one that will finish with all exactly like the pattern is ÷10.

<em>Question</em><em> </em><em>5</em><em>:</em>

We know Logan's watch is still under warranty because,

1 week = 7 days.

6 weeks × 7 days = 42 days

But he has 90 days, so there is still more than 50 days that he can go return it and will get his money back.

<h3>Hope this Helps!!</h3>

:D

FrozenT [24]

Answer:

√(2 - 7x) + 2x = 0

√(2 - 7x) = - 2x

[√(2 - 7x)]² = (- 2x)²

2 - 7x = 4x²

4x² + 7x - 2 = 0

4x² + 8x - x - 2 = 0

4x(x + 2) - (x + 2) = 0

(4x - 1)(x + 2) = 0

4x - 1 = 0 => 4x = 1 => x₁ = 1/4

x + 2 = 0 => x₂ = - 2

Find the value of each variable and the measure of each angle​
Misha Larkins [42]

Answer:

Left angle = 60°

Top angle = 120°

Right angle = 60°

Step-by-step explanation:

Use what you know about angle relationships to set up equations you can solve for each variable.

The top top angle, for example, added to one of the other angles must equal 180° because they are supplementary.

You have two variables, so you need at least two equations (I made three but only used two).

The work is in my attachment, comment of you have questions.
