Answer:

153.86 units^2

Step-by-step explanation:

the area of a circle = pi * r^2

To find r, divide the diameter in half.

14/2 = 7

Now, area = pi * 7^2

= pi * 49

= 153.86

Answer:

-1

Step-by-step explanation:

Gradient is another word for slope, and slope can be defined as rise/run.

From the point (0,0) to (1,-1), it moved one unit down and one unit to the right. The slope for this line can be represented as -1/1, which is equal to -1.

Therefore, the gradient of the graph shown is -1.

Answer:

3/2 or 1.5

Step-by-step explanation:

Answer:

Step 1: Calculate percentage discount

=> $97,899.99 × 25/100

=> 97,899.99/1 × 25/100

{multiply the numerator by the numerator and the denominators by the denominators}

=> 2,447,499.75/100

divide 24,474.9975 by 100

=> 24,474.9975

=> 24,474.9975

{Substract 24,474.9975 from 97,899.99.}

=> 97,899.99 - .24,474.9975

=> 73,424.9925

Step 2: Calculate sales tax rate

Sales tax rate = price × rate/100

=> 73,424.9925 × 3.75/100

=> 275,343.7/100

=> 2,753.437

Add to 73,424.9925

=> 73,424.9925 + 2,753.437

=> 76,178.4295

=> 76,178.4 { Rounded to 1 dp)

Therefore, the total price of the purchases is 76,178.4295

Answer:

1/4

Step-by-step explanation:

Probability = successes / all events

Odds = successes / failures

If the probability is 1/5, then there's 1 success for every 4 failures.

So the odds are 1/4.

Answer:

(4, 14)

Step-by-step explanation:

We are given;

Graph of: y = ax² + c

That it contains point (2, 14)

Now,we want to find which point lies on the graph: y = a(x - 2)² + c.

Now, symbol "a" means the value of horizontal shift because the constants are grouped with x.

If the value of "a" is greater than 0,then it means that the graph shifted to the left by "a" units while if the value of "a" is less than 0,it means the graph shifted to the right by "a" units.

Now, from the 2 graph equations given, and from the principle of graph shifts, we can say that the first graph has shift by 2 units to the right because "a" equals -2.

What this implies is that every point on the graph y = ax² + c shifts by 2 units right.

Thus, the points that lie on the graph y = a(x - 2)² + c are: (x + 2, y)

Thus, points are: (2 + 2, 14) = (4, 14)

Answer:

The correct option is  A

Step-by-step explanation:

From the question we are told that

   The  mean is  [tex]\mu = 0.8 \ pounds[/tex]

    The standard deviation is  [tex]\sigma = 0.25 \ pounds[/tex]

Generally the the probability that a  randomly selected zucchini will weigh between 0 55 pound and 13 pounds is mathematically represented as

       [tex]P(0.55 < X < 1.3) = P(\frac{0.55 - 0.8}{ 0.25} < \frac{X - \mu}{\sigma } < \frac{1.3 - 0.8}{0.25})[/tex]

=>    [tex]P(0.55 <  X  <  1.3)  =  P( -1 <  Z  <  2 )[/tex]

So looking the option of normal curves given in the question we see that it is option A that matches our interval  

x intercepts means the roots of the function .Let's find out

[tex]\\ \rm\Rrightarrow 9m^2+3m-2=0[/tex]

[tex]\\ \rm\Rrightarrow 9m^2-3m+6m-2=0[/tex]

[tex]\\ \rm\Rrightarrow 3m(3m-1)-2(3m-1)=0[/tex]

[tex]\\ \rm\Rrightarrow (3m-2)(3m-1)=0[/tex]

The x-intercepts are -(2/3) and (1/3).

The correct options are (B) and (C)

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. The fact that the coefficient of x² is a non-zero term (a 0) is a necessary need for an equation to be a quadratic equation.

As per the given data:

f(x) = 9m² + 3m - 2

To find the x-intercept of this function:

The roots of f(x) will be the x-intercepts of the given function.

f(x) = 9m² + 3m - 2

9m² + 3m - 2 = 0

9m² - 3m + 6m - 2 = 0

3m(3m - 1) + 2(3m - 1) = 0

(3m + 2)(3m - 1) = 0

The roots are m = -(2/3) and m = (1/3)

Hence, the x-intercepts are -(2/3) and (1/3).

The correct options are (B) and (C)

Answer:

yes because 50 is 10 now and also yes

The surface of the figure is the amount of space on the figure

The new surface area would be half of the original figure

The question is incomplete, so I will give a general explanation.

Assume the surface area of the original figure is A.

Then the area of the new figure would be:

A2 = A * k

Where k is the scale of dilation.

From the question, we have:

k = 1/2

So, the equation becomes

A2 = A * 1/2

This gives

A2 = 1/2A

The above means that the new surface area would be half of the original figure

TheThe statement that  is true about the graph of the line representing Debi’s data is: One lap around the mall is equal to 2,425 steps.

Given:

With the 0 lap she has 1,875 steps

With 1 lap she has 4,300 steps

Hence:

One laps around the mall= 4,300 steps-1,875 steps

One laps around the mall=2,425 steps

Answer: b = √6

Step-by-step explanation: Use the Pythagorean Theorem to solve this.

a² + b² = c²

Plug in your values:

2√3² + b² = 2b²

When a square root is squared, the square root is cancelled out so you will be left with this:

2(3) + b² = 2b²

Subtract b² from both sides so you’re left with:

6 = b²

Now, to get rid of the square, just square root both sides:

√6 = √b²

Since the √6 is not a perfect square, leave it in the radical. Then, you get your answer:

b = √6

Answer:

the answer:b is equivalent to 2

Answer: 80% or 4/5

Step-by-step explanation:

Look at this as a percentage:

75% of $100 leaves you with $25

20% of the remaining $25 gives you $20

$100-$20=80% or 4/5

Step-by-step explanation:

Bottom right is not a function because you would get an infinite number of results. It does not exactly map one output of this function.

The top two graphs are incorrect because they have more than 1 output. You can do the Vertical Line test and see that the top two graphs do have more that one output.

In order for it to be a function it has to have one output.
