find the value a and b for h(x)=x^2+ax+b so h(1)=0 and h'(1)=4

Answers

Answer 1

Answer:

a= -14/3b= 11/3

Step-by-step explanation:

Given Function h(x) = x^2 + ax + bh(1) = 0h'(1) = 4To findValues of a and bSolution

h(1) = 0 ⇒

1^2 + 1*a + b = 0 ⇒a + b = -1      ------------------>   (1)

h'(1) = 4 ⇒ h(4) = 1 ⇒

4^2 + 4*a + b = 1 ⇒4a + b = - 15   ------------------>  (2)

Considering the equation (1) in the equation (2)

3a - 1 = -153a = -14a = - 14/3

and

b = -1 - a b = -1 + 14/3  b = 11/3

12. Factor completely: 64x^3 + 729

Answers

Answer:

(4 x + 9) (16 x^2 - 36 x + 81)

Step-by-step explanation:

Factor the following:

64 x^3 + 729

64 x^3 + 729 = (4 x)^3 + 9^3:

(4 x)^3 + 9^3

Factor the sum of two cubes. (4 x)^3 + 9^3 = (4 x + 9) ((4 x)^2 - (4 x) 9 + 9^2):

(4 x + 9) ((4 x)^2 - 4 9 x + 9^2)

4×9 = 36:

(4 x + 9) ((4 x)^2 - 36 x + 9^2)

Multiply each exponent in 4 x by 2:

(4 x + 9) (4^2 x^2 - 36 x + 9^2)

4^2 = 16:

(4 x + 9) (16 x^2 - 36 x + 9^2)

9^2 = 81:

Answer: (4 x + 9) (16 x^2 - 36 x + 81)

Answer:

(4x+9)(16x2−36x+81)

Step-by-step explanation:

Factor 64x3+729

64x3+729

=(4x+9)(16x2−36x+81)

Marlene decided to buy 2 bags of apples weighing 3 1/4 pounds each, instead of 3 bags weighing 2 2/5 pounds each. Did she end up with more apples or fewer apples by buying the bigger bags?

To find the total weight of 2 bags of apples weighing 3 and 1/4 pounds, multiply.

Answer Choices: 5 1/4, 5 1/2, 6 1/4, 6 1/2.

To find the total weight of 3 bags weighing 2 and 2/5 pounds, multiply.

Answer Choices: 5 2/5, 6 2/5, 7 1/5, 7 2/5.

She ended up purchasing [fewer, more, the same amount of,] apples by buying the bigger bags.

if we have a geometric series with u1 = 2.1 and r= 1.06, what would the least value of n be such that Sn > 5543?

Answers

Answer:

  88

Step-by-step explanation:

Write the expression for the sum in the relation you want.

  Sn = u1(r^n -1)/(r -1) = 2.1(1.06^n -1)/(1.06 -1)

  Sn = (2.1/0.06)(1.06^n -1) = 35(1.06^n -1)

The relation we want is ...

  Sn > 5543

  35(1.06^n -1) > 5543 . . . . substitute for Sn

  1.06^n -1 > 5543/35 . . . .  divide by 35

  1.06^n > 5578/35 . . . . . . add 1

  n·log(1.06) > log(5578/35) . . . take the log

  n > 87.03 . . . . . . . . . . . . . . divide by the coefficient of n

The least value of n such that Sn > 5543 is 88.

What is literal equation?

A literal equation are  type of equations which have two or more unknown variables . A literal equation can be solved by adding or subtracting or multiplying or divide by same numbers to the both sides of the equation in order to solve the expression for the required variable.

For example if an given equation is x+ y =2 and we want to solve it for y

Then we will try to keep y on one side and take remaining terms to other side.⇒ y = x-2  is solution for y.

Given equation :

a- f = q

To solve for a, add f to both sides

⇒ a- f +  f = q+ f

⇒ a = q + f

Solution for a is q +f.

A student did an experiment to test the hypothesis that brand name paper towels soak up water better than generic paper towels. What would be the independent variable in the student's experiment?

Answers

Answer: The independent variable is the brand and the dependant variable is the amount of water you use.

Step-by-step explanation:

The Independent variable is the condition that you change in an experiment.

The dependant variable is the condition that you measure in an experiment.

The independent variable in the student's experiment is the type of paper towel used.

In an experiment, there are three types of variables:

The independent variable : the experimenter can change or manipulate this variable in order to determine its effect on the dependent variable. The dependent variable : this is the variable whose value would be determined in the experiment.The extraneous variable : this is the variable that can affect the result of the experiment but it is not researched in the experiment.

In this question the type of towel used would determine the amount of water that can be absorbed. This makes the type of towel used the independent variable. The dependent variable is the amount of water absorbed.
