For the axis of symmetry it will be -b/2a but in this case the axis of symmetry is going to be y=4. the x intercept will be the roots (2,0) and (6,0) and for the y intercept it will be (0,3) since the parabola crosses the y axis at (0,3)

Doe anyone know this? At least someone have to

Paul [167]

Answer:

While I will not give you an answer, I will tell you how to find it. Don't get scared! I promise it's not complicated. You basically only need to do subtraction.

Concept Explanation:

Okay, so let's start off by defining "complement" and "supplement":

"Complement" - complementary angles: two angles whose sum equals 90°

"Supplement" - supplementary angles: two angles whose sum equals 180°

So, this question is asking you what the other angle is. Based on whether they ask you for the complement or supplement, you only need to subtract the first angle they give you from 90° (if it's asking for the complement) or 180° (if it's asking you for the supplement).

Here are some examples if you're still confused!

--------------------------------------------------------------------------------------------------------------

- What is the complement of a 32° angle?

↓

Since they're asking for the complement, we will subtract 32° (the angle they give us) from 90° (because it's a complement)

↓

90 - 32 = 58

↓

So our answer is: 58°

--------------------------------------------------------------------------------------------------------------

Now let's do a supplement one.

--------------------------------------------------------------------------------------------------------------

- What is the supplement of an 84° angle?

↓

Because they're asking for the supplement, we will subtract 84° (the angle they give us) from 180° (because it's a supplement)

↓

180 - 84 = 96

↓

Then our answer will be: 96°

--------------------------------------------------------------------------------------------------------------

That's all! It's just some subtraction once you know what the vocabulary means. Please comment if you have any other questions.

If you want me to check your answers once you try your problem, I can do that as well!

A drone has an initial velocity of 38m/s. Five seconds later it reaches a velocity

timofeeve [1]

Answer:

The acceleration of the drone is 2.6 m/s²

Step-by-step explanation:

The acceleration is the rate at which the speed changes over time, therefore to solve this question we must divide the change of speed by the elapsed time in order to find the accelaration of the drone in that period. We have:

a = (Vf - Vi)/dt

Where a is the acceleration, Vf is the final velocity, Vi is the initial velocity and dt is the elapsed time. We have:

a = (51 - 38)/5 = 2.6 m/s²

Differentiate with respect to t.. y = b cos t + t2 sin t

Marysya12 [62]

We are given with the expression y = b cos t + t2 sin t and is asked to differentiate the function in terms of t. Based in the power law and law of products, we apply these to the given expresssion. the derivative is y' = -b sin t + t^2 * (cos t) + sin t * 2t. This is equal to y' = sin t (-b +2t) + t^2 cos t.
