PLEASE HELP!!!!! The question is in the image below!!!!

Mathematics
1 answer:
Oxana [17]2 years ago
3 0

Step-by-step explanation:

We must realise that the image of the quadratic curve shown is not showing the full curve. Instead it extends further out.

For all quadratic curves, the domain is all x-values.

We see here that this quadratic curve has an absolute minimum at y = -4 and the curve stretches towards positive infinity.

Hence the range is y >= 4.

The correct answers are the 1st and 5th options.

Hi I need help. I will also tell you this so you don't end up doing it. So the question about Toby is not a problem for you to d

5. 25 = x + 3

It is a one step equation. You just need to subtract 3 on both sides to get x.

6. 2b - 7 = 15

This is a two step equation. You need to add 7 on both sides and then divide both sides by 2 to get b.

7. 10m = 90

Finally, this is a one step equation. You need to divide both sides by 10 to find m.

If (y + 1) varies directly as square root of x and y =14 when x = 27, find the value of y when
marysya [2.9K]

Answer:

22.1 or 22

Step-by-step explanation:

Y + 1 varies√x

Y + 1 = K√x ( k is costant)

so we solve for K

given: 14 + 1 = K√27

15 = K√27

divide both sides by √27

15/√27 = K

to find the value of y

y + 1 = 15/√27 (8) : substitute K for 15/√27

Y + 1 = 120/√27

i.e Y = 120/√27 - 1

Y = 23.1 - 1

Y = 22.1 or 22

What's the name of angle C thanks for the help :)
nikdorinn [45]

Answer:

Reflex angle

Step-by-step explanation:

Properties of reflex angles:

1). Any angle measuring between 180° and 360°.

2). Other side of the reflex angle is either acute or obtuse angle.

By these properties,

Since, angle C measures more than 180° but less than 360° and opposite angle is an acute angle.

By these properties angle C and angle D are the reflex angles.

The ac is a leg of the right triangle <br> True <br> False
Vinil7 [7]

Answer:

False

Step-by-step:

The hypotenuse of the triangle is the side opposite to the right angle. The legs are the other two sides of the triangle. Since AC is on the opposite side of the right angle, it is the hypotenuse and therefore not a leg. Hope this helps!
