If the height of a rectangle is 4.8m and the base is 8.4, what is the perimeter of the rectangle

bija089 [108]

Since the height and base are given those are the lengths of the 2 side lengths so to find the perimeter we do 4.8+4.8+8.4+8.4
the answer should be 26.4!

Answer: so what you would do is would would take the first number that being -2 and add it to the problem like this y=2(-2)+1 and what you do is you times 2 and x2 which give you -4 then you add 1 which gives you -3 so y = -3

Step-by-step explanation:

Y=2(-2)+1 Y=2(-1)+1

-4+1 -3+1

-3 -2

y=2(0)+1 Y=2(1)+1

0+1 2+1

0 3

y=2(2)+1

4+1

Estimate the difference. 9 1/2- 1 6/7

Sav [38]

Answer:

$= 7 \frac{9}{14} \\$

Step-by-step explanation:

$9 \frac{1}{2} - 1 \frac{6}{7} \\ \frac{19}{2} - \frac{13}{7} \\ \frac{133 - 26}{14} \\ = \frac{107}{14} \\ = 7 \frac{9}{14}$

hope this helps

Find the inverse of P(x)=-15x^2+350x-2000 and state it’s domain.

natima [27]

Answer:

The function given is:

P(x) = 15x² + 350x - 2000

y = 15x² + 350x - 2000

Interchange x and y:

x = 15y² + 350y - 2000

x = (y√15)² + 2(y√15)(45.19) + (45.19)² - (45.19)² - 2000

x = ( y√15 + 45.19)² - 4042.14

( y√15 + 45.19)² = x + 4042.14

Take square root:

y√15 + 45.19 = (√(x + 4042.14))

y√15 = (√(x + 4042.14)) - 45.19

$y = \sqrt{\frac{x+4042.14}{15}}-11.67$

$f^{-1}(x) = \sqrt{\frac{x+4042.14}{15}}-11.67$

The minimum value of x, for which function is defined and real, is x= -4042.14

Hence, the range of inverse is x ≥ -4042.14
