Answer:

  (c)  factoring and the zero-product principle

Step-by-step explanation:

Factoring is always an efficient method of solving a quadratic, if it has nice integer factors that can be easily identified. Here, the two prime factors of 35 have a sum of 12, so the factored form is easily found to be ...

  (x +5)(x +7) = 0

This basically shows you the solutions are x=-5 and x=-7 "by inspection" in one step.

By contrast, the quadratic formula has 4 multiplications, a division, a square root, and 3 additions. That's a significant amount of arithmetic to get to the answers.

Factoring is the most efficient way to solve this quadratic.

Total in account after 5 years:

The difference in totals:

After 5 years Jack will have $0.66 more money in his account than David.

This is a type of interest that is compounded after time period it is said to be compounded. After that particular period, the interest is calculated and then added with the principle. For the next duration, the interest is calculated on the sum.

Here, to find the amount of money after n years, we need to use the formula S = P(1 + r)ⁿ.

For David, S = sum of money after the total period of investment.

P = Principle = $350, r = rate of interest = 3% compounded annually, n = time period = 5 years.

Now, S = $350(1 + 3/100)⁵ = $350(1 + 0.03)⁵ = $350(1.03)⁵ = $405.75

Hence, after 5 years, David will have $405.75 in his bank account.

For Jack, S = sum of money after the total period of investment.

P = Principle = $350, r = rate of interest = 3% compounded quarterly, n = time period = 5 years.

Now, S = $350(1 + 3/ 4× 100)⁵ˣ⁴ = $350(1 + 0.0075)²⁰ = $350(1.0075)²⁰ = $406.41.

Hence, after 5 years, Jack will have $406.41 in his bank account.

Therefore, Jack will have $(406.41 - 405.75) = $0.66 more money than David.

What formula are you using I'm using the one below so hopefully you're able to utilize this.

C = (F-32) ÷ 1.8

C = (56-32) ÷ 1.8

C = ( 24 ) ÷ 1.8

C = 13.3333333

Rounding one decimal place (tenths)

C = 13.3

The value which is equivalent to the 1 in 8 chance of the player winning a game is Choice J: 0.125.

The question statement implies that the probability of a player winning a game is 1 in 8.

We must know that the probability of an event occuring can be expressed as any choice of real numbers. However, the probability must ultimately not be more than 1 upon evaluation.

Answer:

the answer is 30% hope this helps you

Answer:

30%

Step-by-step explanation:

The two outcomes (can work the problem and can't work the problem) are complementary.

In probability theory, the complement of any event A is the event [not A], i.e. the event that A does not occur. The event A and its complement [not A] are mutually exclusive and exhaustive.

Complementary events are two outcomes of an event that are the only two possible outcomes.

Complementary outcomes add to 1 or 100%.

100 - 70 = 30.

Answer:

639.48

Step-by-step explanation:

Answer:

0.477121=−log(3x+7)+0.30103

Step 1: Flip the equation.

−log(3x+7)+0.30103=0.477121

Step 2: Add -0.30103 to both sides.

−log(3x+7)+0.30103+−0.30103=0.477121+−0.30103

−log(3x+7)=0.176091

Step 3: Divide both sides by -1.

log(3x+7)=−0.176091

Step 4: Solve Logarithm.

log(3x+7)=−0.176091

10log(3x+7)=10−0.176091

3x+7=0.666667

3x+7−7=0.666667−7(Subtract 7 from both sides)

3x=−6.333333

m < 2 = 104°

Step-by-step explanation:

Given that < 3 is a supplement of < 2, and that m < 3 = 76°, then:

To find the measure of m < 2, all you need to do is subtract the m < 3 from 180°.

m < 2 = 180° - m < 3

m < 2 = 180° - 76°

m < 2 = 104°

Answer:

x = 7 is not there in the domain of the function.

Step-by-step explanation:

The value of x = -3 would not be in the domain of the function

We have the following information available from the question is:

The function is :

[tex]f(x) =\frac{x-2}{x+3}[/tex]

Determine the values of x would not be in the domain of the function

Now, According to the question:

The function is :

[tex]f(x) =\frac{x-2}{x+3}[/tex]

Let the denominator equal to zero: x + 3 = 0

Rearrange unknown terms to the left side of the equation.

x + 3 = 0

x = -3

Hence, The value of x = -3 would not be in the domain of the function.

Sample space is a set that contains all the possible outcomes for an event.

For salad:

Choices for extra toppings (mushrooms, olives) =2

Choices for meats (bacon, eggs) =2

Choices for dressings (vinaigrette, honey mustard.)= 2

By Fundamental counting principal .

The number of different salads can be made= (Choices for extra toppings) x (Choices for meats ) x (Choices for dressings)

Answer:

45in & 87in^2

Step-by-step explanation:

W = 7*2.5in=17.5in

L = 2*2.5in=5in

Perimeter = 2(L+W)

2(5in+17.5in)

45in

Area = L*W

17.5in*5in=87in^2

Remember, Perimeter is linear while area is squared.
