Step-by-step explanation:

Given f(x)= √4x and g(x)=1/x-4. which value is the domain of f o g? A. 4 B. 1. C. 5 D. -3

Answers

The domain of f o g is all x-values less than or equal to 1/4. So, the correct answer is B. 1.

What is Function ?

Function can be defined in which it relates an input to output.

To determine the domain of f o g, we need to first find the composition of f and g.

f o g(x) = f(g(x))

= √4(1/x - 4) = √(4/x - 16)

The domain of f o g is the set of all x-values for which the expression √(4/x - 16) is defined.

For the expression under the square root to be defined, we need:

4/x - 16 ≥ 0

4/x ≥ 16

x ≤ 4/16

x ≤ 1/4

Therefore, the domain of f o g is all x-values less than or equal to 1/4. So, the correct answer is B. 1.

Mina has £3.20. If she gives half to her brother how much money does she have left?

Answers

Amount of money Mina has : £3.20

Half of her money : ½ × 3.20 = £1.6

So, She gives her brother £1.6
Money left with her : Total money - Money given to her brother = £3.20 - £1.60 = £1.60

2. Which is larger?The common ratio, r , in a geometric sequence whose second term is
24 and whose fifth term is 1536
or
The common difference, d , in an arithmetic sequence whose fourth
term is 16 and whose seventh term is 31.

Answers

Answer:

The common difference d is larger than the common ratio r

Step-by-step explanation:

The common difference in the arithmetic sequence $d=u_(n)-u_(n-1)$

The nth term in the arithmetic sequence is $a_(n)=a+(n-1)d$ , where a is the first term

The common ratio in the geometric sequence $r=(u_(n))/(u_(n-1))$

The nth term in the geometric sequence is $a_(n)=a(r)^(n-1)$ , where a is the first term

Geometric sequence

∵ The second term is 24

∴ $u_(2)$ = 24

∵ $u_(2)=a(r)^(2-1)=ar$

- Equate it by its value

∴ ar = 24 ⇒ (1)

∵ The fifth term is 1536

∴ $u_(5)$ = 1536

∵ $u_(5)=a(r)^(5-1)=ar^(4)$

- Equate it by its value

∴ $ar^(4)$ = 1536 ⇒ (2)

Divide (2) by (1)

∴ $(ar^(4))/(ar)=(1536)/(24)$

- Divide up and down by ar

∴ r³ = 64

- Take ∛ for both sides

∴ r = 4

Arithmetic sequence

∵ The fourth term is 16

∴ $u_(4)$ = 16

∵ $u_(4)$ = a + (4 - 1)d

∴ $u_(4)$ = a + 3 d

- Equate it by its value

∴ a + 3d = 16 ⇒ (1)

∵ The seventh term is 31

∴ $u_(7)$ = 31

∵ $u_(7)$ = a + (7 - 1)d

∴ $u_(7)$ = a + 6 d

- Equate it by its value

∴ a + 6 d = 31 ⇒ (2)

Subtract equation (1) from equation (2) to eliminate a and find d

∵ (a - a) + (6 d - 3 d) = (31 - 16)

∴ 3 d = 15

- Divide both sides by 3

∴ d = 5

∵ r = 4 and d = 5

∴ d > r

∴ The common difference d is larger than the common ratio r

True or false: You can represent the following situation with a division expression.Joshua has three cats. Over a week they eat a total of 14 pounds of food. On average how much food does each cat eat in a week?

True

False

Answers

Answer:

true

Step-by-step explanation:

Answer:

true

Step-by-step explanation:

To represent the situation, you would have to do 14÷3 because there are 3 cats that eat 14 pounds of food in a week and to figure out how much a cat eats in a week, you would have to divide.
