Answer: To use the calculator: Enter the corresponding values into the boxes below and ... to and add to. i) In a quadratic equation in the form ax2 bx c 0, if.

Step-by-step explanation:

According to the information, we can infer that some coordinates of this quadratic equation are: (-2, -3), (-1, -0.75), (0, 0), (1, -0.75), and (2, -3)

To solve the quadratic equation, we need to set the equation equal to zero:

Now, we can divide both sides by -0.75 to isolate x^2:

Taking the square root of both sides, we get:

Therefore, the solution to the quadratic equation s(x) = -0.75x^2 is x = 0.

According to the previous information, we can infer that the equation s(x) = -0.75x^2 represents a downward facing parabola. Here are 5 possible coordinates on this curve:

Answer:6 inches.

Step-by-step explanation: What is the radius of a circle with an area of 113.04 square inches?

Radius of the circle is of 3 inches.

Step-by-step explanation:

It is given that the area of the circle is 113.04,

Let the radius of the circle be of "a" units

=======================

From the properties of circle, we know : -

Area of circle = πr^2 , where r is the radius of the circle.

======================

Then, comparing the question with the identity :

= > πr^2 = 113.04 sq. inches

= > 3.14 x r^2 =  113.04 sq. inches

= > r^2 = 113.04 / 3.14 sq.inches

= > r^2 = 36 sq. inches

= > r = 6 inches

Hence,

r or radius of the circle is of 6 inches.

Answer: 200/7

Step-by-step explanation:

This creates 3 similar right triangle

you would put similar parts  on top and the similar parts on bottom of proportions.

ex.

[tex]\frac{hypotenuse}{short leg} = \frac{hypotenuse}{short leg}[/tex]

in your problem they gave the short legs and long legs of right triangel

The line that they share in middle of the triangle is the long leg for the triangle on right and it is also the short leg for triangle on left.

[tex]\frac{long leg}{short leg} =\frac{long leg}{short leg}[/tex]

[tex]\frac{x}{20} = \frac{20}{14}[/tex]

x=(400)/14 = 200/7

You could also make your proportion where

parts of 1 triangle = equivalent parts of the other

ex.

[tex]\frac{long leg from big triangle}{long leg from small triangle} = \frac{short leg big triangle}{short leg from small triangle}[/tex]

Answer:

Step-by-step explanation:

4 + 4 + circumference of the circle

Formula for circumference of a circle is 2 · π · radius, but can also be written as π · diameter

4 + 4 + (15 · π)

4 + 4 + (15 · 3.14)

4 + 4 + 47.1

8 + 47.1

55.1

Answer:

About 59.66 inch

Step-by-step explanation:

To find the circumference you first have to find the diameter which is the double the radius. Since 9.5 is the radius of this circle, the diameter is, 9.5x2=19.

With the diameter of 19, you multiply the 19 with pie which is approximately 3.14. The answer is 19x3.14=59.66

Answer:

36.85 ft

Step-by-step explanation:

3 feet on either end + 6 feet on either side + circumference of the circle

3 + 3 + 6 + 6 + circumference of the circle

18 + circumference of the circle

You can find the circle's diameter by subtracting 6 from 12.  You get 6.  You can find the radius by dividing the diameter by 2.  You get 3.

The formula for circumference is 2·π·Radius

2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85

Answer:

D. None of the above.

Step-by-step explanation:

To evaluate the expression when x = 6, we substitute 6 for x in the expression:

2 - 3(x - 5)

= 2 - 3(6 - 5)

= 2 - 3(1)

= 2 - 3

= -1

Therefore, the value of the expression when x = 6 is -1.

So, the answer is D. None of the above.

Answer: none of the above

Step-by-step explanation:

When x = 6 We substitute 6 for x in the expression:

2 - 3(x - 5)

2 - 3(6 - 5)

2 - 3(1)

2 - 3

= -1

Answer:

(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Step-by-step explanation:

The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Step-by-step explanation:

Pick two points that the line overlaps. We can see the points are on (0,63) (2,42) and (4,21). Lets use (2,42) and (4,21). To find the rate of change (m) the formula needed is y^2 - y^1 divided by x^2 - x^1. 21-42=-12 over 4-2=2. So we get -10.5 for the rate of change.

Answer:

The Answer to the first question is 27 cubic millimeters.

Step-by-step explanation:

The original formula for volume is V= l×w×h

When you find the volume of a cube, use this formula; V=s^3.

V is for Volume.

s is for the measurement of the side.

3 is for the length, width, and height.

First,  just plug the number in;  V=3^3. Or 3×3×3.

Second, Multiply; V=27

Unable to determine given the data.

Step-by-step explanation:

You can't determine the mode because you would need the set list of numbers, and not just the box plot.

Answer:

unable to determine the given data

Step-by-step explanation:

The mode is the value in a set that appears most often.

In order to identify the mode, we would need the set of numbers.

Because, we are only given the box plot, we cannot find the number that appares the most , so we are unable to determine the given data.

Answer:

x = 19

Step-by-step explanation:

We can see that the angles (2x + 4) and (8x - 14) are supplementary — they add to 180. From this observation, we can form the equation that can be solved for x:

(2x + 4) + (8x - 14) = 180

↓ combining like terms

10x - 10 = 180

↓ adding 10 to both sides

10x = 190

↓ dividing both sides by 10

x = 19

The time needed for the rocket to be 30 feet of the ground is given as follows:

t = 9.6 seconds.

The quadratic function giving the rocket's height after t seconds is given as follows:

h(t) = -16t² + 150t + 70.

The rocket will be 30 feet of the ground when:

h(t) = 30.

Hence:

-16t² + 150t + 70 = 30

16t² - 150t - 40 = 0.

The coefficients of the quadratic function are given as follows:

a = 16, b = -150, c = -40.

Time is a positive measure, hence, using a quadratic function calculator, the positive root is given as follows:

t = 9.6 seconds.

Box and Whisker Plot

box plot

Description

A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles.

The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles. Outliers are sometimes plotted as individual dots that are in-line with whiskers. Box Plots can be drawn either vertically or horizontally.

Although Box Plots may seem primitive in comparison to a Histogram or Density Plot, they have the advantage of taking up less space, which is useful when comparing distributions between many groups or datasets.

Here are the types of observations one can make from viewing a Box Plot:

What the key values are, such as: the average, median, 25th percentile, etc.

If there are any outliers and what their values are.

If the data is symmetrical or not.

How tightly is the data grouped.

If the data is skewed and if so, in what direction.

Two of the most commonly used variation of Box Plot are: variable-width Box Plots and notched Box Plots.
