When you are on the 2nd step of factoring this trinomial,you should be listing the factors of?

Answers

Given:

The trinomial equation is given as,

[tex]3v^2-4v-7[/tex]

The objective is to choose the correct value for which the factors are to be obtained for factorization.

Explanation:

From the step 1, to perform the factorization the values of a and c has to be multiplied.

Then in step 2, the factors need to be calculated for the product of a and c.

Product of a and c :

The product of a and c will be,

[tex]a\times c=3\times7=21[/tex]

Thus, factors are to be listed for the number 21.

Hence, option (1) is the correct answer.

A forest products company claims that the amount of usable lumber in its harvested trees averages142 cubic feet and has a standard deviation of 9 cubic feet. Assume that these amounts haveapproximately a normal distribution.1. What percent of the trees contain between 133 and 169 cubic feet of lumber? Round to twodecimal places.II. If 18,000 trees are usable, how many trees yield more than 151 cubic feet of lumber?

Answers

[tex]\begin{gathered} I)84\% \\ II)2857 \end{gathered}[/tex]

1) Considering that the amount of lumber in this Data Set has been normally distributed, then we can start by finding this Percentage (or probability in this interval, writing out the following expressions:

[tex]\begin{gathered} P(133Now we can replace it with the Z score formula, plugging into that the Mean, the Standard Deviation, and the given values:

[tex]Z=\frac{X-\mu}{\sigma}[/tex]

Then:

[tex]\begin{gathered} P(\frac{133-142}{9}<\frac{X-\mu}{\sigma}<\frac{169-142}{9}) \\ P(-1Checking a Z-score table we can state that the Percentage of the trees between 133 and 169 ft³ is:

[tex]P(-12) Now, let's check for the second part, the number of trees. But before that, let's use the same process to get a percentage that fits into that:

[tex]\begin{gathered} P(X>151)=\frac{151-142}{9}=1 \\ P(Z>1)=0.1587 \end{gathered}[/tex]

Note that 0.1587 is the same as 15.87%. Multiplying that by the total number of trees we have:

[tex]18000\times0.1587=2856.6\approx2857[/tex]

Rounding it off to the nearest whole.

Using the Distributive Property, which of the following expressions are equivalent to 7 x 6? Select all that apply. A. (6 x 7)+(6 x 7)
B. (5×6) + (2 × 6)
C. (7 x 6) + (1 x 6)
D. (7 x 6) + (2 x 6)
E. (2 x 6)+(5 x 6)

Answers

By using the Distributive Property, the equivalent expression to 6 x 7 is option (B) (5 x 6) + (2 x 6) and option (E) (2 x 6) + (5 x 6).

Distributive property:

The distributive Property defines that when a factor is multiplied by the addition of two terms, it is essential to multiply each of the two numbers by the factor, and finally perform the addition operation.

This property can be stated symbolically as:

A ( B+ C) = (A x B) + (A x C)

Where A, B and C are three different values.

Given,

Here we have the expression 7 x 6.

Now, we need to find the equivalent expression by using the distributive expression.

AS per the definition of distributive property,

First we have o identify in which term is got separated,

Here they separated the term 7.

So, there three way for dividing it,

They are,

6 + 1 = 7

2 + 5 = 7

3 + 4 = 7

Based on these, we have two way to write the expression,

one is,

(5 x 6) + (2 x 6)

Another way is,

(2 x 6) + (5 x 6)

So, the correct options are option (B) and (E).

Function f is defined by f(x) = 2x – 7 and g is defined by g(x) = 5*

Answers

Answer

f(3) = -1, f(2) = -3, f(1) = -5, f(0) = -7, f(-1) = -9

g(3) = 125, g(2) = 25, g(1) = 5, g(0) = 1, g(-1) = 0.2

Step-by-step explanation:

Given the following functions

f(x) =2x - 7

g(x) = 5^x

find f(3), f(2), f(1), f(0), and f(-1)

for the first function

f(x) = 2x - 7

f(3) means substitute x = 3 into the function

f(3) = 2(3) - 7

f(3) = 6 - 7

f(3) =-1

f(2), let x = 2

f(2) = 2(2) - 7

f(2) = 4 - 7

f(2) =-3

f(1) = 2(1) - 7

f(1) = 2 - 7

f(1) =-5

f(0) = 2(0) - 7

f(0) =0 - 7

f(0) = -7

f(-1) = 2(-1) - 7

f(-1) = -2 - 7

f(-1) = -9

g(x) = 5^x

find g(3), g(2), g(1), g(0), and g(-1)

g(3), substitute x = 3

g(3) = 5^3

g(3) = 5 x 5 x 5

g(3) = 125

g(2) = 5^2

g(2) = 5 x 5

g(2) = 25

g(1) = 5^1

g(1) = 5

g(0) = 5^0

any number raised to the power of zero = 1

g(0) = 1

g(-1) = 5^-1

g(-1) = 1/5

g(-1) = 0.2

Answers

Answer:

Allison must score 280 on Exam B to do equivalently well as she did on Exam A

Explanations:

Note that:

B is a midpoint of AC

Since B is the midpoint, we can write:

What is the equation of a horizontal parabola?

An horizontal parabola of vertex (h,k) is modeled as follows:

In which:

The directrix is x = h - p.The focus is (h + p, k).

In the context of this problem, we have that:

The directrix is x = -4.The focus is: (1,3), hence k = 3.

A system of equations is built for h and p as follows:

h - p = -4.h + p = 1.

Hence:

2h = -3

h = -3/2.

p = 1 + 3/2 = 2.5.

An athlete runs at a speed of 9 miles per hour. If one lap is 349 yards, how many laps does he run in 22 minutes

Answers

The athlete will cover 17 yards in 22 minutes of his running.

What is unitary method?

The unitary method is a method in which you find the value of a single unit and then the value of a required number of units.

Given is an athlete who runs at a speed of 9 miles per hour and one lap is 349 yards.

We will use the unit conversions to solve the given problem.

The speed of the athlete is 9 mph. We can write it as -

9 mph = (9 x 1760) yards per hour = 15840 yards per hour.

15840 yards per hour = (15840/60) yards per minute = 264 yards per min.

Total yards covered in 22 minutes = 22 x 264 = 5808 yards

one lap is equivalent to 349 yards.

1 yard is equivalent to (1/349) laps

5808 yards are equivalent to (5808/349) or 16.6 yards or approximately 17 yards.

Therefore, the athlete will cover 17 yards in 22 minutes of his running.

the discriminant equation How many real solution 4x^2-8x+10=-x^2-5 have?

Answers

Answer:

0 real solutions

Explanation:

First, we need to transform the equation into the form:

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

So, the initial equation is equivalent to:

[tex]\begin{gathered} 4x^2-8x+10=-x^2-5 \\ 4x^2-8x+10+x^2+5=-x^2-5+x^2+5 \\ 5x^2-8x+15=0 \end{gathered}[/tex]

Now, the discriminant can be calculated as:

[tex]b^2-4ac[/tex]

If the discriminant is greater than 0, the equation has 2 real solutions.

If the discriminant is equal to 0, the equation has 1 real solution

If the discriminant is less than 0, the equation has 0 real solutions

So, in this case, a is 5, b is -8 and c is 15. Then, the discriminant is equal to:

[tex](-8)^2-4\cdot5\cdot15=84-300=-236[/tex]

Since the discriminant is less than zero, the equation has 0 real solutions

Suppose elephant poaching reduces an initial animal population of 25,000 animals by 15% each year. 1. Find the rate of change.2. How many animals will be left in 10 years?

Answers

Answer

Initial animal population, P₀ = 25,000

1. Rate of change = 15% = 0.15

2. Animal left in 10 years?

To calculate the animals left in 10 years, we use the formula:

P(t) = P₀ (1 - r)^t in t years

t = 10, P₀ = 25,000, r = 15% = 0.15)

P₍₁₀₎ = 25000 (1 - 0.15)¹⁰

P₍₁₀₎ = 25000 (0.85)¹⁰

P₍₁₀₎ = 25000 (0.1969)

P₍₁₀₎ = 4922.50

Therefore, 4922.50 animals will be left in 10 years.

[tex]\begin{gathered} 9+24i-16+2x+2yi \\ (-7-2x)+i(24+2y)\text{ = x+ iy} \\ \end{gathered}[/tex]

Finally writing those two expressions as a System of equations we have:

[tex]\begin{gathered} \begin{cases}-7-2x=\text{ x} \\ 24+2y=y\end{cases} \\ -7-2x=x\Rightarrow-7=2x+x\Rightarrow3x=7\Rightarrow\frac{3x}{3}=\frac{7}{3} \\ 24+2y=y\Rightarrow24=-2y+y\Rightarrow-y=24\Rightarrow y=-24 \\ S=\mleft\lbrace(\frac{7}{3},-24)\mright\rbrace \end{gathered}[/tex]

3) Hence, the answer is S={(-24,7/3)}

A park meadow is planted with wildflowers. The Parks Department plans to extend the length of the rectangular meadow by x meters. Which expressions represent the total area, in square meters, after the meadow's length is increased? Select all that apply. 15. A 310 + x B 15.5(20x) C 20x + 15.5 D 15.5x + 310 E 15.5(20 + x) F 35.5 + x Ilse the distributi

Answers

We have the following:

The area would be the length by the width, but since x amount was added to the length, it would be like this

[tex]\begin{gathered} A=w\cdot l \\ w=15.5 \\ l=20+x \end{gathered}[/tex]

replacing

[tex]A=15.5\cdot(20+x)=310+15.5x[/tex]

Therefore, the answer is E and D
