i really need to find out how to find a,b, and c in the quadratic formula can u please help ASAP will mark as BRAINLIEST!!

Answers

Answer:

Brainliest, please! (Answer below)

Step-by-step explanation:

The basic form for any quadratic function is:

ax^2 + bx + c.

The constant of the 1st term, the x^2 constant, is a, the constant of the second term, the x constant, is b, and the constant, the third term, is c. There are some instances where there will not be a b or c. For example, x^2 + 2, or 3x^2 - 4x. However, there must always be an a, or else the function isn't quadratic.

Carson buys eggs and lemons at the store.
He pays a total of $39.62.
He pays $6.74 for the eggs.
He buys 8 bags of lemons that each cost the same amount.

Which equation could be used to determine xx, how much each bag of lemons costs?

Answers

Answer:

8x  = 39.62 - 6.74

Step-by-step explanation:

Cost of 1 bag of lemons = $ x

Cost of 8 bags of lemons = 8 *x = 8x

Cost of 8 bags of lemons = Total cost - cost of the eggs

                              8x           = 39.62 - 6.74

Answer:

In triangle ABC, m ZA = 47°, m ZB = 62°. m ZC =
a. 81°
b. 61°
C. 71
d. 51°

Answers

Answer:

m ZC = 71 degrees. Option C.

Step-by-step explanation:

Triangles always measure a total of 180 degrees.

47 + 62 + c = 180

109 + c = 180

c = 71

Answer:

71°

Step-by-step explanation:

The total angles in a triangle should equal 180°

a + b + c = 180

47 + 62 + c = 180

109 + c = 180

180 - 109 = 71

c = 71°

Jasper Hall sells farm chemicals. He is paid a commission of 99% of his first $6,000 in sales during the month and 14% on all sales over $6,000. What is his commission in a month in which he has sales worth $16,120? ​

Answers

Amount of total commission is $1,956.8 (Approx.)

Given:

Percent of commission upto $6,000 sale = 9% (Misprint)

Percent of commission over $6,000 sale = 14%

Amount of total sales = $16,120

Find:

Amount of total commission

Computation:

Amount of commission upto $6,000 sale = 6000 × 9%

Amount of commission upto $6,000 sale = $540

Amount remain = 16120 - 6000

Amount of commission upto $6,000 sale = $10,120

Amount of commission over $6,000 sale = 10,1200 × 14%

Amount of commission over $6,000 sale = $1,416.8

Amount of total commission = Amount of commission upto $6,000 sale + Amount of commission over $6,000 sale

Amount of total commission = 540 + 1,416.8

Amount of total commission = 1956.8

Amount of total commission = $1,956.8 (Approx.)

Step-by-step explanation:

Find the difference within each number:

7 -> 10: + 3

10 -> 14: + 4

With each difference, + 1 is added so we can infer the next difference will be + 5.

14 + 5 = 19

Next is + 6.

19 + 6 = 25

Many doctors rely on the use of intravenous medication administration in order to achieve an immediate response of a particular drug's effects. The concentration, C, in mg/L, of a particular medication after being injected into a patient can be given by the function C of t is equal to the quantity negative 10 times t squared plus 50 times t end quantity over the quantity t squared plus 4 times t plus 3 end quantity comma where the time, t, is hours after injection. Part A: What is the domain of the function C(t) based on the context of the problem? Show all necessary calculations. (5 points) Part B: Graph the function to determine the greatest concentration of the medication that a patient will have in their body. (5 points)

Answers

Graphs are used to show the relationship between variables, where the variables are represented by a pair of axes.

The domain of the function is [tex]t \ge 0[/tex] The greatest concentration of the medication is 5mg/L

Given that:

[tex]C(t) = \frac{-10t^2 + 50t}{t^2 + 4t + 3 }[/tex]

(a): The domain of the function

Because the medication concentration C(t) is a function of time (t), the domain is the possible values t can take.

t, cannot take negative values (i.e. it is not possible to have a negative time).

The least possible value of t is 0

So, the domain of the function based on the context is:

[tex]t \ge 0[/tex]

(b) The greatest concentration of the medication

From the graph (see attachment), the maximum y-value is 5.

Hence, the greatest concentration of the medication is 5 mg/L
