Answer:

We conclude that:

h(f(-1))  = -2

∴ option D i.e. -2 is correct.

Step-by-step explanation:

Given

f(x) = 4x² - 1

g(x) = 1/2x + 5

h(x) = 2(x - 4)³

To determine

h(f(-1)) = ?

In order to determine h(f(-1)) first we need to determine f(-1).

substitute x = -1 in the function f(x) = 4x² - 1

f(-1) = 4(-1)² - 1

f(-1) = 4(1) - 1

f(-1) = 4-1

f(-1) = 3

so

h(f(-1)) = h(3)

now substitute h = 3 in the function h(x) = 2(x - 4)³

h(x) = 2(x - 4)³

h(3) = 2(3 - 4)³

h(3) = 2(-1)³

h(3) = 2(-1)

h(3) = -2

Thus,

h(f(-1)) = h(3) = -2

Hence, we conclude that:

h(f(-1))  = -2

∴ option D i.e. -2 is correct.

Braden's credit card balance was $162. If
he charges $54 then makes a $75 payment,
find the balance on his card.

Answers

Answer:the answer is 33

Step-by-step explanation:

The balance on the credit card will be $33.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Braden's credit card balance was $162. He charged $54 then makes a $75 payment the balance amount will be calculated as below:-

Balance = 162 - 75 - 54

Balance = 162 - 129

Balance = $33

Therefore, the balance on the credit card will be $33.

David has counters. Lisa has 5 more counters than David. Samia has 4 times as many counters as David. The total number of counters is . Write a formula for in terms of . Give your answer in its simplest form.

Answers

Answer:

if 'c' equals number of counters, the answer is 6c + 5

Step-by-step explanation:

david has 'c'

lisa has '5+c'

samia has '4c'

add all terms together:  c + 5 + c + 4c = 6c + 5

The formula for the total number of counters in terms of x is T = 6x + 5

What is the algebraic expression?

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Let's start by expressing the number of counters Lisa has in terms of x. We know that Lisa has 5 more counters than David, so:

Lisa = David + 5

Lisa = x + 5

Next, we need to express the number of counters Samia has in terms of x. We know that Samia has 4 times as many counters as David, so:

Samia = 4 × David

Samia = 4x

Finally, we can express the total number of counters in terms of x by adding up the number of counters each person has:

T = David + Lisa + Samia

T = x + (x + 5) + 4x

T = 6x + 5

Therefore, the formula for the total number of counters in terms of x is T = 6x + 5.

A large university accepts 70​% of the students who apply. Of the students the university​ accepts, 40​% actually enroll. If 30,000 students​ apply, how many actually​ enroll?

Answers

8400 because you take 70% of 30000 which is 21000, then you take 40% of 21000, which is 8400

Answer:

8400 students

Step-by-step explanation:

Applicants = xAccepted = 70% ⇒ 0.7xEnrolled = 40% ⇒ 0.4(0.7x) = 0.28x

We got x = 30000

Then number of actually enrolled is:

30000*0.28 = 8400 students
