types of quadratic equation

Answers

Answer:

1) Standard form: y = ax2 + bx + c where the a,b, and c are just numbers.

2) Factored form: y = (ax + c)(bx + d) again the a,b,c, and d are just numbers.

3) Vertex form: y = a(x + b)2 + c again the a, b, and c are just numbers.

Solve the following equation for A. Be sure to take into account whether a letter is capitalized or not. b=f^2A+2HA

Answers

Answer:

A = [tex]\frac{b}{f^2+2H}[/tex]

Step-by-step explanation:

Given equation is,

b = f²A + 2HA

To solve this equation for the value of A we will isolate A in one side of the equation.

b = A(f² + 2H)

By dividing the equation by (f² + 2H) on both the sides of the equation.

[tex]\frac{b}{f^2+2H}=\frac{A(f^2+2H}{(f^2+2H)}[/tex]

A = [tex]\frac{b}{f^2+2H}[/tex]

Therefore, answer will be A = [tex]\frac{b}{f^2+2H}[/tex]

Set up a system of linear equations to represent the scenario. Solve the system by using Gaussian elimination or Gauss-Jordan elimination. Assume the interest rates are annual. Latoya borrowed $19,500 to buy a truck for her business. She borrowed from her parents who charge her 5% simple interest. She borrowed from a credit union that charges 4% simple interest, and she borrowed from a bank that charges 3% simple interest. She borrowed four times as much from her parents as from the bank, and the amount of interest she paid at the end of 1 yr was $870. How much did she borrow from each source

Answers

Answer:

p = $12,000

c = $4,500

b = $3,000

Step-by-step explanation:

Denote the variables as follows:

p = amount borrowed from parents

c = amount borrowed from the credit union

b = amount borrowed from the bank

The equations that can be formed using the given information are as follows:

p + c + b = 19500... (i)

p = 4b... (ii)

The formula to compute simple interest is:

SI = P × (R/100) × T

So, the equation for the total interest paid at the end of 1 year is:

0.05p + 0.04c + 0.03b = 870

5p + 4c + 3b = 87000... (iii)

Substitute (ii) in (i) and (iii) and simplify as follows:

4b + c + b = 19500

⇒ c + 5b = 19500... (iv)

5(4b) + 4c + 3b = 87000

⇒ 4c + 23b = 87000... (v)

Subtract (iv) from (v):

4c + 23b = 87000

(-)c + (-)5b = (-)19500 ] × 4

⇒

4c + 23b = 87000

-4c - 20b = -78000

⇒

3b = 9000

b = 3000

Compute the value of p as follows:

p = 4b = 4 × 3000 = 12000

p = 12000

Compute the value of c as follows:

p + c + b = 19500

12000 + c + 3000 = 19500

c + 15000 = 19500

c = 4500

Thus, the amount borrowed from each source is:

p = $12,000

c = $4,500

b = $3,000

Johnny was able to drive an average of 27 miles per hour faster in his car after the traffic
cleared. He drove 25 miles in traffic before it cleared and then drove another 104 miles. If the
total trip took 3 hours, then what was his average speed in traffic?

Answers

Answer: 40 mph

Step-by-step explanation: let s = speed in traffic

(s+17) = out of traffic

Write a time equation; time = dist/speed

traffic time + normal speed time = 4 hrs

46%2Fs + 80%2F%28%28s%2B17%29%29 = 4

multiply by s(s+17) to cancel the denominators

46(s+17) + 80s = 4s(s+17)

46s + 782 + 80s = 4s^2 + 68s

126s + 782 = 4s^2 + 68s

Arrange as a quadratic equation on the right

2s^2 - 29s - 391 = 0

Use the quadratic formula a=2; b=-29; c=-391

I got a positive solution of

s = 23 mph in traffic

Check this by finding the actual times. Normal speed: 23 + 17 = 40 mph

46/23 = 2 hrs in traffic

80/40 = 2 hrs at normal speed

----------------------------

total time 4 hrs

0 = 4s^2 + 68s - 126s - 782

4s^2 - 58s - 782 = 0

simplify, divide by 2

so the answer is 40mph

I am a multiple of 6. I am also a multiple of 4. I am less than 30.

Answers

Answer:

12 and 24

Step-by-step explanation:

First, we need to list out the common multiples of 4 nd 6, less than 30

[tex]4 = 0.4,8,12,16,20,24,28[/tex]

[tex]6 = 0.6,12,18,24[/tex]

Then, we list out the common multiples

[tex]Common\ Multiple = 12,24[/tex]

Since, only 12 and 24 fall in this category.

Then the number is either 12 or farm

Nina's garden is 4 1/5 meters long and 3/qo meters wide. What is the area of Nina's garden?

Answers

Answer: 63/50 meters^2 or in mixed number 1 13/50 meters^2

Step-by-step explanation:

area= length x width

length = 4 1/5= 21/5 . multiply the whole number with the denominator 4x5= 20 add 20 with the numerator 20+1=22

width = 3/10

21/5 x 3/10 ( multiply the denominators together)

21x3 / 5x10

= 63/50 meters^2 or in a mixed number 1 13/50 meters^2

(by the way I'm guessing you meant 3/10 and not 3/q0)

The IQ of 10 adults is measured, and the results are 83, 87, 90, 92, 93, 100, 104, 111, 115, 121. Find the range of the data set. (4 points)

A: 83−121

B: 38

C: 96.5

D: 204

Answers

Answer:

Step-by-step explanation:

range = biggest - smallest

121 - 83 = 38

range = 38

the correct answer is B: 38, representing the difference between the highest and lowest values in the data set, and it correctly reflects the range of the given IQ scores.

To find the range of the data set, we need to determine the difference between the highest and lowest values in the set. Given the IQ scores of the 10 adults as 83, 87, 90, 92, 93, 100, 104, 111, 115, and 121, the highest value is 121, and the lowest value is 83.

Thus, the range can be calculated as 121 - 83, which equals 38. Therefore, the correct answer is B: 38, representing the difference between the highest and lowest values in the data set, and it correctly reflects the range of the given IQ scores.
