Answer 1

Answer:

Step-by-step explanation:

1.Consider the quadratic relation y = x^2 – 6x – 16.

a) Factor this equation using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).

[y = x^2 – 6x – 16 : Two numbers when multiplied = -16, but when added = -6, would be: -8 and 2. [-8+2 = -6, and -8*2 = -16] This would lead to (x+2)(x-8) as the two factors.

b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.

(x+2)=0; x= -2

(x-8)=0; x = 8

2. Consider the quadratic relation y = 2x^2 + 6x – 80.

a) Factor this equation by:

1. Determining the greatest common factor (GCF).

The GCF is 2: 2*(x^2 + 3x - 40)

2. Factoring the equation using common factoring.

2*(x^2 + 3x - 40): Two numbers that when multiplied = -40, but added = 3, would be 8 and -5. So we can factor:

2*(x + 8)(x - 5)

3. Factor the expression inside the brackets using the Trinomial Method (find two numbers that multiply to 'c' and add to 'b'; the factored form has 2 pairs of brackets).

2*(x + 8)(x - 5)

b) Find the x-intercepts (zeroes) of the relation. Remember to let y = 0 then solve for each x separately.

0 = (x + 8) and 0=(x - 5); x = -8, and x=5

how do you solve n - 8 > 5

Answers

Answer:

n great than 13.

hope this isn't wrong

The solution to the inequality is n > 13. This means that any value of n greater than 13 will satisfy the inequality.

Given is an inequality n - 8 > 5, we need to solve it,

To solve the inequality "n - 8 > 5," you can follow these steps:

Step 1: Add 8 to both sides of the inequality to isolate the variable n.

(n - 8) + 8 > 5 + 8

n - 8 + 8 > 13

n > 13

Step 2: Simplify the inequality.

n > 13

Hence the simplified inequality is n > 13.

Answers

Answer:

18°

Step-by-step explanation:

1. ∠A and ∠B are complementary angles, so they add up to 90°.

This means that 2x - 4 + 5x + 17 = 90

2. To find the measure of ∠A, we first have to solve for x.

3. (Solving)

Step 1: Simplify both sides of the equation.

[tex](2x+5x)+(-4+17)=90[/tex] [tex]7x+13 = 90[/tex]

Step 2: Subtract 13 from both sides.

[tex]7x + 13 - 13 = 90 - 13[/tex] [tex]7x = 77[/tex]

Step 3: Divide both sides by 7.

[tex]\frac{7x}{7} = \frac{77}{7}[/tex] [tex]x = 11[/tex]

4. Now that we know x = 11, let's plug that value into (2x - 4) to find the measure of Angle A.

[tex]2(11)-4[/tex] [tex]22-4[/tex] [tex]18[/tex]

Therefore, the measure of ∠A = 18°.

Answer:

m<A = 18

Step-by-step explanation:

Since <A and <B are complementary angles, that just means those 2 angles combined equal 90:

<A + <B = 90

2x - 4 + 5x + 17 = 90

7x + 13 = 90

7x = 90 - 13

7x = 77

x = 77/7

x = 11

m<A:

2x - 4

2(11) - 4

Evaluating expressions involve substituting the given value for x into the equation.

After 3.5 days, the height of the plant is ______
centimeters.

The height of the plant is 6.25 centimeters after _______
days.

Answers

Answer: I think this is what the top answer meant. Let me know if I am wrong though!

After 3.5 days, the plant is 5.75 centimeters tall, and after 4.5 days, it is 6.25 centimeters tall.

Given that a function h = 0.5d + 4 showing the height h of a plant in d days,

So, the equation of the line is:

h = 0.5d + 4

For 3.5 days put d = 3.5,

h = 0.5(3.5) + 4

h = 5.75 cm

To find the number of days after height of the plant is 6.25 centimeters.

Put h = 6.25,

6.25 = 0.5d + 4

2.25 = 0.5d

d = 4.5 days

Hence, the plant is 5.75 centimeters tall after 3.5 days and 6.25 centimeters tall after 4.5 days.

Using the variance concept, it is found that the correct option is:

B. must be at least zero

The mean of a data-set is the sum of all observations divided by the number of observations.The variance of a data-set is the sum of the differences squared between each term and the mean, divided by the number of values.

Since the variance is squared, it's minimum value is 0, and thus, the correct option is:

Answer:

Volume of cylinder = 2,198 cm

Solution:

volume of a cylinder = area of base(pi × radius²) × altitude (height)

Step-by-step explanation:

Evaluate g(2) , then substitute the value obtained into f(x)

g(2) = 2(2) + 11 = 4 + 11 = 15 , then

f(15) = 3(15) - 15 = 45 - 15 = 30

Step-by-step explanation:

[tex]f(x) = 3x - 15 \\ g(x) = 2x + 11 \\ f(g(x)) = 3(2x + 11) - 15 \\ f(g(x)) = 6x + 33 - 15 \\ f(g(x)) = 6x + 18 \\ f(g(2)) = 6(2) + 18 \\ f(g(2)) = 12 + 18 \\ \boxed{f(g(2)) = 30}[/tex]

f(g(2)) = 30 is the right answer.
