Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.

Interpreting the graph, it is found that the function has two real solutions

The number of different real solutions that a function has is given by the number of times it crosses the x-axis(also known as the horizontal axis) on the graph. If the graphs of the equations intersect, then there is one solution that is true for both equations.

In this problem, the function crosses the x-axis, at 0 and -4

Using the above we find that the given graph has solution at the x intercepts.

X intercepts are 0 and -4

Hence the solutions are two real and they are x=0 and x =-4

Answer:

b₂ = [tex]\frac{2A}{h}[/tex] - b₁

Step-by-step explanation:

A = [tex]\frac{b_{1}+b_{2} }{2}[/tex] × h ( multiply both sides by 2 to clear the fraction )

2A = h(b₁ + b₂ ) ← divide both sides by h

[tex]\frac{2A}{h}[/tex] = b₁ + b₂ ( subtract b₁ from both sides )

[tex]\frac{2A}{h}[/tex] - b₁ = b₂

The solution is, the formula to find the base b₂ is : b₂ = 2A/h - b₁.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

The area of a trapezoid is calculated using the formula below, where A is the area of the trapezoid, b₁ and b₂ are the bases of the trapezoid, and h is the height of the trapezoid.

A = (b1+b2)/2 × h

( multiply both sides by 2 to clear the fraction )

2A = h(b₁ + b₂ )

← divide both sides by h

2A/h = b₁ + b₂

( subtract b₁ from both sides )

2A/h - b₁ = b₂

The critical value used is (10 – 2.5, 10 + 2.5) when, the mean is 10 and confidence level is 89%.

The confidence interval for a population with a known standard deviation is based on the fact that the sample means follow an approximately normal distribution. Suppose

mean = 10

as, we have 89% confidence interval (5, 15)

where EBM = 5.

To get 89% confidence interval,

mean = 10 of the normal distribution.

Then, the critical value we use is

(10 – 2.5, 10 + 2.5).

So, the critical value used is (10 – 2.5, 10 + 2.5) when, the mean is 10 and confidence level is 89%.

Here, Nt is the quantity after time t, N0 is the initial quantity, t1/2 is the half-life, and t is time.

For the first situation, Nt=360, N0=900, t=10 minutes. Therefore, substituting the given values get the value of t1/2. So,

[tex]\begin{aligned}360&=900\left(\frac{1}{2}\right)^{\frac{10}{t_{1/2}}} \\\frac{360}{900}&=\left(\frac{1}{2}\right)^{\frac{10}{t_{1/2}}}\\0.4&=\left(\frac{1}{2}\right)^{\frac{10}{t_{1/2}}}\\ \ln(0.4)&=\frac{10}{t_{1/2}}\ln(0.5)\\t_{1/2}&=10\times\frac{\ln(0.5)}{\ln(0.4)}\\&=7.6\end{aligned}[/tex]

Now, According to the question:

Your grandmother is 87 years old and she told you that all of her friends are women. There is no single man in her circle of friends. She also told that it is rare to see a man over the age of 85. It is because of the fact that women are more in number than man above the age of 85 and this ratio is like 100 men per 200 women, which means the chances of getting a male friend is almost half after the age of 85. So women are more in number than men.

An integer's factors are other integers that, when multiplied, give the same result as the original integer. For instance, 33 and 55 are factors of 1515 since 35=1535=15. Knowing what a factor is, we frequently seek to identify an integer's "factorizations".

An integer is represented as the product of its factors in a factorization. The number 11 and the initial integer are always factors, as you can see. This is referred to as a "prime" or complete factorization of 88. The base number, in this case 22, is therefore prime. A prime integer is one with only itself and the number 11 as components. 11 is not a prime number by definition. Prime factors can be used to factor polynomials. Because the elements x+1x+1 and x+2x+2 are irreducible—they only have 11 and themselves as factors—the second factorization is known as the prime factorization. Similar to factoring integers into a product of integers, each smaller than the original, factoring polynomials aims to describe the original polynomial as a product of polynomials of lower degree.

We have given that,

a rocket rises at 5 ft/s between 0 and 10 seconds,

therefore

V₁ = 5 ft/s

T₁ = 10 seconds

Height in first 10 seconds = ?

we know the formula to find the height,

i.e Height = velocity × time

⇒ H₁ = V₁ × T₁

        = 5 × 10

   H₁ = 50 ft

Therefore height of the rocket in the first 10 seconds is 50 ft.

Now it given that, rocket rises at 25 ft/s for another 15 seconds.

i.e V₂ = 15 ft/s

    T₂ = 15 seconds

    H₂ = ?

H₂ = V₂ × T₂

H₂ = 225 ft

Therefore height of the rocket in next 15 seconds is 225 ft.

Now we will find the height of the rocket at the end of the 25 seconds.

As per the given simple interest, the amount invested in each account is 50000, 60000, and 10000 respectively.

Simple interest:

In math, the method of calculating the interest amount for a particular principal amount of money at some rate of interest is known as simple interest.

Given,

Pierre inherited $506,000 from his uncle and decided to invest the money. He put part of the money in a money market account that earns 4.5% simple Interest. The remaining money was invested in a stock that returned 5% in the first year and a mutual fund that lost 4% in the first year. He invested $10,000 more in the stock than in the mutual fund, and his net gain for 1 yr was $3060.

Here we need to determine the amount invested in each account.

Let us consider the total amount invested on is written as,

=> X+Y+Z = 120000

And according tot he given details we know that,

=> Y = Z + 10000

AS we apply the interest, then we get,

=> 0.022X + 0.06y - 0.02Z = 2820  

Apply the value of y as z + 10000, then  we get,

=> X+(Z+10000) + Z = 120000

=> 0.022X + 0.06(Z+10000) - 0.02Z = 2820

Then we simplify this one then we get,

=> X + 2Z = 110000

=> 0.022X + 0.06Z + 600 - 0.02Z = 2820

=> 0.022(110000 - 2Z) + 0.06Z + 600 - 0.02Z = 2820

=> 2420 - 0.044Z + 0.06Z + 600 - 0.02Z  = 2820

=>3020 - -0.004z = 2820

=> 0.004z = 200

Now, the probability that the class average is less than 79.

P(∑x < 79) = P( (∑x - μ) / (σ/√n)  < (79 - 80) / (6 /√30) )

                = P( (∑x - μ) / (σ/√n)  < (-1) / 1.09 )

                = P( (∑x - μ) / (σ/√n)  < -1 )     [Round off the Denominator it gives 1]
