Answers

Answer 1

Answer:

p(x) as a product of linear factors. [tex]p(x)=(x+3)(x-2)(x+6)[/tex]

Step-by-step explanation:

(x+3) is the factor of polynomial [tex]p(x) = x^3 + 7x^2 - 36[/tex]

So, we can divide [tex]p(x) = x^3 + 7x^2 - 36[/tex] by (x+3) to find other factors

The division is shown in figure attached.

The quotient is: x^2+4x-12

Now factoring the quotient to find linear factors

[tex]x^2+4x-12\\=x^2+6x-2x-12\\=x(x+6)-2(x+6)\\=(x-2)(x+6)[/tex]

The factors are [tex](x+3)(x-2)(x+6)[/tex]

So, p(x) as a product of linear factors. [tex]p(x)=(x+3)(x-2)(x+6)[/tex]

Explain why the exponent in 3.5 x 10 6 is 6 there are only 5 zeros in 3500000

Answers

Step-by-step explanation:

The given number is 3.5×10⁶. It is written in scientific form. We can first write it into standard form. There is exponent of 10 is 6.

3.5×10⁶ = 3.5×1000000

We can write 3.5 as 35/10

So,

3.5×10⁶ = (35/10)×1000000

= 3500000

One of the zero of 1000000 is divided by 10 at the denominator. Hence, the exponent in 3.5×10⁶ is 6 while there are 5 zeros in 3500000.

Using the "fives fact" (5 x 6 = 30) as a starting point, we added one more group of 6 to reach the final result of 36.

To use the "fives fact" to solve 7 x 6, we can break it down into simpler calculations using the fact that 5 x 6 = 30.

Here's the step-by-step calculation:

1. Start with the "fives fact": 5 x 6 = 30.

2. Since we need to find 7 x 6, we can add another 6 to the result of 5 x 6:

  30 + 6 = 36

Therefore, 7 x 6 equals 36.

2. If OQ and RT are parallel lines which statement is true?
A) RSP is congruent to RSU
B) RSP is congruent to PST
C) RSP is congruent to TSU
D) RSP is congruent to OPS (my answer)

Answers

Answer:

1. A) OPS is congruent to RSU

2. C) RSP is congruent to TSU

Step-by-step explanation:

1. Since OQ and RT are parallel lines that are cut across by the transversal line, NU, therefore, angle OPS and angle RSU are corresponding angles formed. Corresponding angles are congruent.

✅Therefore: A) OPS is congruent to RSU. OPTION A IS TRUE.

❌OPS and RSP are consecutive interior angles. They are not congruent. They are supplementary. So, option B is NOT TRUE.

❌OPS and OPN are linear pair angles. Linear pair angles are not congruent. They are supplementary. Therefore, OPTION B IS NOT TRUE.

OPS and TSU are also not congruent.

2. Angle RSP and angle RSU are vertical angles. Vertical angles are congruent. Therefore, the statement that IS TRUE is:

C) RSP is congruent to TSU

In a basketball tournament, Team A scored 5 fewer than twice as many points as Team B. Team C scored 80 more points than Team B. The combined score for all three teams was 983 points. Write an equation to represent this scenario using the variable b to represent Team B’s total points.

Team B =
Team C =
The equation representing this scenario is
.

Answers

Answer:

Team A = 449

Team B = 227

Team C = 307

Equation is

(2b-5) + b + (b+80) = 983

simplyfying

4b+75 = 983

Step-by-step explanation:

Take 4b+75 = 983

b = (983 - 75)/4 = 227

now

Team A = 5 less than twice as many as team B = 2b - 5 = 2 *227-5 = 454-5= = 449

Team B = b = 227

Team C = 80 more than team B = b+80 = 227+80 = 307

or you can just subtract 983 - (Team A +Team B)

Answer:

Team A = 449

Team B = 227

Team C = 307

Equation is

(2b-5) + b + (b+80) = 983

4b+75 = 983

Step-by-step explanation:

Makayla borrows $15200. Some is from her friend at 5% annual interest, 2 times as much as that from her bank at 8% , and the remainder from her insurance company at 4%. She pays a total of $968 in interest for the first year. How much did she borrow from each source?

Answers

Answer:

Amount borrowed from friend = 4000

From Bank = 8000

From insurance = 3200

Step-by-step explanation:

Given that:

Amount borrowed = $15200

Let amount borrowed from friend = x

x at 5% = 0.05x

From Bank = 2x at 8% = 0.08*2x = 0.16x

From insurance = 15200 - (x + 2x) at 4%

From insurance = 15200 - 3x at 4% ; (15200 - 3x)* 0.04 = 608 - 0.12x

Interest paid in first year = $968

Simple interest = principal * rate * time

968 =

968 = (0.05x + 0.16x + 608 - 0.12x)

968 - 608 = 0.05x + 0.16x - 0.12x

360 = 0.09x

x = 360 / 0.09

x = 4000

Hence,

Amount borrowed from friend = 4000

From Bank = 2x = 4000 * 2 = 8000

From insurance = 15200 - (4000 + 8000) = 3200
