Answer:

b. maximum height: 5.6 ft

c. 0.3 sec to reach its maximum height

Step-by-step explanation:

y = -16x² + 10x + 4   ...(1)

d/dx: -32x + 10 = 0

x = 5/16 ≈ 0.3   ... plug in (1)

y = -16*(0.3)² + 10*0.3 + 4 = 5.56 ≈ 5.6

Answer:

I think it is B

Step-by-step explanation:

Angle AMB is not more than 90 and less than 180 degrees, and neither is angle BMC. Therefore, neither angle is obtuse.

In [tex]\angle[/tex] A, [tex]\angle[/tex] BMC is an obtuse angle.

In [tex]\angle[/tex] B, [tex]\angle[/tex] AMB is an obtuse angle.

In [tex]\angle[/tex] D, [tex]\angle[/tex] AMB is an obtuse angle.

But, in C there are two right angles

Therefore, two right angles exist supplementary.

When the sum of the measures of two angles is 180°, such angles are called supplementary angles and each of them is called a supplement of the other.

Two angles exist named supplementary when their measures count up to 180 degrees. By the explanation of obtuse angles, the angles that estimate more significant than 90° exist as obtuse. If we add two obtuse angles, the sum will be more significant than 180°. It will not help the results of the supplementary angles when we add obtuse angles.

In [tex]\angle[/tex] A, [tex]\angle[/tex] BMC is an obtuse angle.

In [tex]\angle[/tex] B, [tex]\angle[/tex] AMB is an obtuse angle.

In [tex]\angle[/tex] D, [tex]\angle[/tex] AMB is an obtuse angle.

But, in C there are two right angles

The two right angles exist supplementary.

Therefore, the correct answer is option B.

Answer:

-6 degrees each minute

Step-by-step explanation:

if the temperature fell 48 degrees in 8 minutes, we must divide 48 by 8.

48 / 8 = 6

It fell 6 degrees every minute

Since we are talking about temperature dropping, it is negative

-6 degrees each minute

Answer:

It fell 6 degrees each minute

Step-by-step explanation:

I think you divide 48 by 8 so yeah it falls 6 degrees per minute if every fall is the exact same. You are welcome

Step-by-step explanation:

Use Pythagorean theorem to find the distance and make a right triangle.

So then..

a² + b² = c²

3² + 9² = c²

c² = 9 + 81

c² = 90

c² = [tex]\sqrt{90}[/tex]

The student's conclusion is incorrect because there is exactly one solution to the equation and this can be determined by using the arithmetic operations.

GIven :

A student concluded that 8x - 12 = 4( 1/2x - 6 ) has infinity many solutions.

The following steps can be used in order to determine the statement that describes the student's conclusion:

Step 1 - Write the given linear equation.

[tex]8x - 12 = 4 (\dfrac{1}{2}x-6)[/tex]

Step 2 - Simplify the above equation.

8x - 12 = 2x - 24

Step 3 - Subtract 2x on both sides in the above equation.

8x - 2x - 12 = 2x - 2x - 24

6x - 12 = -24

Step 4 - Add 12 on both sides in the above equation.

6x - 12 + 12 = 12 - 24

6x = -12

Step 5 - Divide by 6 on both sides in the above equation.

x = -2

Therefore, the correct option is B) The conclusion is incorrect because there is exactly one solution to the equation.
