Please I really need help on these two

Mathematics
1 answer:
oksian1 [2.3K]2 years ago
3 0

Answer:

1) 5

2) (3 , 24)

Step-by-step explanation:

Question 1

f(x) x= 1    2 * 5¹ = 10

f(x) x= 2    2 * 5² = 50

f(x) x= 3    2 * 5³ = 250

multiplicative rate of change = 50/10 = 5

check: 250/50 = 5

Question 2

f(x) = 2 * 4ˣ

(3 , 24)     f(3) = 2 * 4³ = 2 * 64 = 128 ≠ 24

Given:

L=2\dfrac{1}{2} ft and W=3\dfrac{2}{5} ft.

P=2L+2W

To find:

The value of P.

Solution:

We have,

P=2L+2W

Substituting L=2\dfrac{1}{2} and W=3\dfrac{2}{5}, we get

P=2\times 2\dfrac{1}{2}+2\times 3\dfrac{2}{5}

P=2\times \dfrac{2(2)+1}{2}+2\times \dfrac{3(5)+2}{5}

P=2\times \dfrac{5}{2}+2\times \dfrac{17}{5}

P=5+\dfrac{34}{5}

Taking LCM, we get

P=\dfrac{5(5)+34}{5}

P=\dfrac{25+34}{5}

P=\dfrac{59}{5}

P=11\dfrac{4}{5}

Therefore, the value of P is 11\dfrac{4}{5} ft.

Please help me in the question of commission ! Grade - 9 . ​
AlladinOne [14]

Answer:

Step-by-step explanation:

Commission for  amount  Rs. 5,00,00 = \frac{2}{100}*500000

                                                               = 2* 5000

                                                               = Rs. 10,000

total commission = Rs. 32,000

Remaining commission = 32500 - 10000

                                      = Rs. 22500

Let remaining amount of the restaurant = Rs. x

Commission on Rs. x = 22500

3% of x = 22500

\frac{3}{100}*x=22500\\\\x=22500*\frac{100}{3}\\\\x = 7500*100

x = Rs. 750000

Price of the restaurant = 750000 + 500000

                                     =Rs . 1250000

A teacher writes an inequality x divided by 6 < -2 on the board. Vincent incorrectly solves the inequality and obtains x <
scZoUnD [109]

The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

Step-by-step explanation:

Given inequality that the teacher wrote is:

\frac{x}{6} -2

Solving an inequality means that the variable should be isolated on left side of the inequality.

So multiplying both sides by 6

6* \frac{2}{6} < -2 * 6\\x < -12

Vincent got the answer is x<-2 = > The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides
