kondaur [170]

The square root of 100 is 10. The drawing must be 10 cm by 10 cm.

1 cm = 2 ft, so 10 cm must equal 20 feet.

20 * 20 = 400 square feet :)

This equation shows how the time required to ring up a customer is related to the number of items being purchased. t = 4p + 20 T

konstantin123 [22]

Answer:

6 items are being purchased

Step-by-step explanation:

Given that variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer, If it takes 44 seconds to ring up a customer then the number of items being purchased may be computed by substituting the value of t into the given equation

t = 4p + 20.

Using t = 44

44 = 4p + 20

collect like terms or subtract 20 from both sides

44 - 20 = 4p

24 = 4p

Divide both sides by 4

24/4 = p

p = 6

The function f(x) = x2 is transformed to f(x) = −1.4x2. Which statement describes the effect(s) of the transformation on the gra

Romashka-Z-Leto [24]

Answer:

C) The parabola is narrower and reflected across the x-axis.

Step-by-step explanation:

The original parabola has equation:

$f(x) = {x}^{2}$

The transformed parabola has equation

$f(x) = - 1.4 {x}^{2}$

How wide the graph is can be determined by the absolute value of the coefficient.

The smaller the absolute value of the coefficient, the wider the graph.

Since

$|1| \: < \: | - 1.4|$

The original graph is wider than the transformed graph.

Also the negative factor tells us there is a reflection in the x-axis.
