Answer:

The midpoint is ( -2.5, 6.5)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2

(-2+-3)/2 = -5/2 = -2.5

To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2

(6+7)/2 = 13/2 = 6.5

The midpoint is ( -2.5, 6.5)

Answer:

From the given figure, we can see that the 2 given line segments are equal in length

Hence,

11 + (x - 5) = 2x - 4

6 + 4 = x

x = 10

Now that we know the value of x, we can use it to get the length of the line segment UW

UW = 11 + (x - 5)

UW = 11 + (10 - 5)

UW = 11 + 5

UW = 16 units

Answer:

The days will it take the store to make $50,000 in a whole number are:

Step-by-step explanation:

Remember that x represents the number of days, so, you must replace different values in the formula until you obtain a value of $50,000, in this form:

So, I'll show you that the value that you need is 30 in a whole number.

I know that the value exceeds the amount of $50,000, but if you use just a day before:

How you can see, if you use 29 days, the value doesn't reach $50,000, by this reason, you must use 30 days to reach it.

Regression equations can be linear, quadratic or exponential

The graph that would most likely be associated with the given model is (b)

The regression equation is given as:

[tex]n(t) = 3.53t^2 - 33.04t + 117.56[/tex]

The above regression equation is a quadratic function (and non-linear).

So, the graph must represent a non-linear relationship.

From the given graphs, only graph (b) represents a quadratic function.

Other options are either linear models or exponential.

Hence, the graph that would most likely be associated with the given model is (b)

Answer:

2.93

Step-by-step explanation:

3.15×7/100=0.2205

3.15-0.2205=2.9295

The cost of the jeans before tax $2.9295

"It is a number or ratio that can be expressed as a fraction of 100."

For given example,

Let 'a' be the original price of the jeans.

Let 'b' be the price of the jeans with tax.

then, b = a + tax

Juan paid $3.15 in tax for the jeans.

The sales tax on a pair of jeans is 7 percent.

First we find the tax on a pair of jeans.

⇒ tax = b × 7%

⇒ tax = 3.15 × (7/100)

⇒ tax = $0.2205

We need to find the cost of the jeans before tax.

Here, b = $3.15, tax amount = $0.2205

⇒ b = a + 0.2205

⇒ 3.15 = a + 0.2205

⇒ a = 3.15 - 0.2205

⇒ a = $2.9295

Therefore, the cost of the jeans before tax $2.9295

Answer:

5(y - 2)

Step-by-step explanation:

What is the GCF (Greatest Common Factor) for 5y and -10? It is 5 so you take  5 out of 5y and 5 out of -10. You put the 5 outside of the parentheses and put y - 2 inside of the parentheses. That is how you factorize 5y - 10

The factorized form of 5y - 10 is 5(y - 2).

Factorization in mathematics is the process of dividing a large number into smaller ones that when multiplied together, give you the original number. Factorization is the process of dividing a number into its components or divisors.

When we are asked to factorize an expression, we are essentially trying to write the expression as a product of simpler expressions. In this case, we want to write 5y - 10 as a product of simpler expressions.

One way to approach this is to look for a common factor that is present in both terms of the expression.

In this case, we can see that both 5y and 10 are divisible by 5. Therefore, we can factor out the greatest common factor of the two terms, which is 5.

When we factor out 5 from 5y and -10, we are left with:

5y - 10 = 5(y - 2).

The time when the ball hit the ground, which is thrown from a height of 70 meters with an initial downward velocity of 10 m/s is 2.87.

A quadratic equation is the equation in which the unknown variable is one and the highest power of the unknown variable is two.

The standard form of the quadratic equation is,

[tex]ax^2+bx+c=0[/tex]

Here,(a,b, c) is the real numbers and (x) is the variable. To solve the equation for x, use the following formula,

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

The ball's height h (in meters) after t seconds is given by the following.

[tex]h=70-10t-5t^2[/tex]

The ball is thrown from a height of 70 meters with an initial downward velocity of 10 m/s. In this case,

The time when the ball hit the ground has to be find out. The value of the height when it hit the group is zero. Put the value of h=0 in the above equation,

[tex]h=70-10t-5t^2\\0=70-10t-5t^2\\5t^2+10t-70=0\\5t^2+10t-70=0\\[/tex]

Solve the quadratic equation using the following formula,

[tex]t=\dfrac{-10\pm \sqrt{10^2-4(10)(-70)}}{2\times5}\\t=-4.87, t=2.87[/tex]

Consider positive value. Thus, the time when the ball hit the ground, which is thrown from a height of 70 meters with an initial downward velocity of 10 m/s is 2.87.

Answer:

98,000 bacteria.

Step-by-step explanation:

We are given the formula:

[tex]P=le^{kt}[/tex]

Where l is the initial population, k is the rate of growth, and t is the time ( in hours).

We know that it has an initial population of 500. So, l is 500.

We also know that the population grows to 7000 after 2 hours.

And we want to find the population after 4 hours.

First, since we know that the population grows to 7000 after 2 hours, let's substitute 2 for t and 7000 for P. Let's also substitute 500 for l. This yields:

[tex]7000=500e^{2k}[/tex]

Divide both sides by 500:

[tex]e^{2k}=14[/tex]

We can solve for the rate k here, but this is not necessary. In fact, when can find our solution with just this.

Let's go back to our original equation. We want to find the population after 4 hours. So, substitute 4 for t:

[tex]P=500e^{4k}[/tex]

We want to find the total population, P. Notice that we can rewrite our exponent as:

[tex]P=500(e^{2k})^2[/tex]

This is the exact same thing we acquired earlier. So, we know that the expression within the parentheses is 14. Substitute:

[tex]P=500(14)^2[/tex]

Square and multiply:

[tex]P=500(196)=98000[/tex]

So, after 4 hours, there will be 98,000 bacteria.

And we're done!

Step-by-step explanation:

Answer:

There were 7 small boxes and 14 large boxes shipped.

Step-by-step explanation:

This problem may be solved by a system of equations:

I am going to say that:

x is the number of small boxes used

y is the number of large boxes used

There were twice as many large boxes shipped as small boxes shipped

This means that y = 2x

Each small box of paper weighs 45 pounds and each large box of paper weighs 80 pounds. The total weight of all boxes was 1435 pounds.

This means that 45x + 80y =1435

So we have to solve the following system:

y=2x

45x + 80y =1435

45x + 80 (2x) = 1435

205x = 1435

x= 1435/205

x=7

y=2x= 2(7) = 14

There were 7 small boxes and 14 large boxes shipped.
