Select all the correct locations on the graph. At which points are the equations y = x2 + 3x + 2 and y = 2x + 3 approximately equal? 2.

Answer:

The equations are approximately equals at the points (0.618,4.236)(0.618,4.236) and (-1.618,-0.236)(−1.618,−0.236)

Answer:

36°

Step-by-step explanation:

108°+ 108°+ 2x+ 2x =360°

4x +216° = 360°

4x= 360°- 216°

Just X= 144°/4

=36°

2x= 2(36)

= 72°

Answer:

Answer:

x = 3/2 | y = -3

Step-by-step explanation:

Given equations:

Substituting from equation (i) for y:

==> 2x - 6 = -4x + 3

==> 2x + 4x = 6 + 3

==> 6x = 9

dividing both sides by 3:

==> 2x = 3

==> x = 3/2

Substituting 3/2 for x in equation (i):

==> y = 2(3/2) - 6

==> y = 3 - 6

==> y = -3

[tex] - 4x + 3 = 2x - 6 \\ 6x = - 9 \\ 2x = - 3 \\ x = - 1.5[/tex]

Step-by-step explanation:

The volume of a triangular prism shaped box is 2,400 cubic centimeters.

Base of the triangle = 16cm

Sides of the triangle = 17cm

Length of the box = 20cm

Triangular prism

A triangular prism is a three-sided prism made of a triangular base and a corresponding side.

A. To find the height of the base = 3 x the volume divided by the base area = 15cm.

B. The approximate amount of card board used to make the candy box:

Using the lateral prism as the sides will be:

Lateral area =  Perimeter of triangle X height of the prism

Lateral area =  (16 + 17 + 17) X 20

Lateral area =  50 X 20

Lateral area =  1,000 cm2

Therefore, the answer is 1000cm2.

Answer: 33r + 9s

Step-by-step explanation: First, we need to distribute

the 3 through both terms inside the set of parenthses.

Students will often multiply the 3 by the 3s but forget

to multiply the 3 by the 9r, beware of this mistake.

So we get 6r + 9s + 27r which simplifies to 33r + 9s.

The equivalent expression is 33r + 9s

The expression is given as:

6r + 3(3s + 9r)

Expand the expression

6r + 9s + 27r

Collect like terms

6r + 27r + 9s

Evaluate the like terms

33r + 9s

Hence, the equivalent expression is 33r + 9s

Answer:  (3000)*(0.09)*(4) = $1,080.00

Step-by-step explanation:

When money is borrowed, interest is charged for the use of that money over a certain period of time. The amount of interest charged depends on the amount of money borrowed, the interest rate and the length of time for which the money is borrowed.

Principal is the amount of money borrowed. The interest rate is given as a percent. Time is the length of time in years for which the money was borrowed.

Interest = Principal * Rate * Time which is also written as I = P*R*T

Principal = $3,000, Interest rate = 0.09 and Time = 4

Raquel had to pay back $3,000 in principal plus $1,080 in interest for a total of $4,080.00

(3000)*(0.09)*(4) = $1,080.00

By using the graph, we will see that k = 1.85

Here we have the exponential function:

f(x) = k*(3)^x

And we want to find the value of k.

To find it, we need to use one point on the graph. the only one easy to read is the one for x = 3, we can see that when x = 3, f(x) = 50.

Then we have:

f(3) = 50 = k*(3)^3 = k*(3*3*3) = 27*k

Solving that for k we get:

50 = 27*k

50/27 = k = 1.85

Angle of elevation is angle measured from horizontal line to line of sight, The distance from the plane to the observer is 25,636 feet approx

You look straight parallel to ground. But when you have to watch something high, then you take your sight up by moving your head up. The angle from horizontal line to the point where you stopped your head is called angle of elevation. See the figure where angle OPD is the angle when observer saw the plane. It  is measured from the horizontal line OD.

Refer to the attached figure.

It is given that we have

Length of PD = |PD| = 21,000 feet

Angle ∠OPD = 55°

Assuming length of OP = |OP| = x feet, we get the sin ratio as

[tex]sin(55^\circ) = \dfrac{|PD|}{|OP|} = \dfrac{21000}{x}\\\\x = \dfrac{21000}{\sin(55^\circ)} \approx 25636.27 \approx 25636 \: \rm feet[/tex]

Where m is the gradient and c is the y-intercept

In this equation +30 is the y-intercept

Answer:

The y-intercept is 30 in this equation

Step-by-step explanation:

This equation is in slope-intercept form.

Slope intercept form includes two things, (you can probably already guess)

It includes the slope of the line and the y-intercept

In all slope-intercept form equations the 20x would be the slope and the 30 would be the y-intercept
