You need to buy new tile for your kitchen. it measures 13.25 feet by 7.5 feet. what is the area of the kitchen that you calculated? what is the most accurate area you can report to your hardware store in order to purchase enough tile?

Answers

Answer 1
Answer: The area of the kitchen is given by multiplying the length by the width

Area = 13.25×7.5 = 99.375 feet²

To make sure that we buy enough tiles, it is best to round the area to the nearest tenth or better still round up to the nearest integer

99.375 in nearest tenth is 99.4
99.375 rounded up to the nearest integer is 100

Tx^2+3x-7=0 has two real solutions. What can be deduced from value of T?

Answers

Answer:

T > -9/28

Step-by-step explanation:

A quadratic has two real solutions when the discriminant (b² - 4ac) is positive.

b² - 4ac > 0

3² - 4(T)(-7) > 0

9 + 28T > 0

28T > -9

T > -9/28

100 is the regular price if you buy one and get the other half price. Explain how this different from getting a 50% discount?

Answers

100 = x + x/2

3x/2 = 100

x = 200/3

if there was 50% discount:

buying 1 would be $33.33

buying 2 would be $66.67

What is the equation of the translated function, g(x), if f(x) = x2? g(x) = (x + 5)2 + 2 g(x) = (x + 2)2 + 5 g(x) = (x – 2)2 + 5 g(x) = (x – 5)2 + 2

Answers

Given the graph of the function f(x) which is described by a parabola with the vertex at (0, 0) and the graph of the translated function g(x) which is described by a parabola with the vertex at (5, 2).

Notice, that the vertex of the translated function is 5 units to the right and 2 units up of the graph of f(x).

Thus, g(x) is obtained by translating the function f(x) 5 units to the right and 2 units up.

Recall that given a function described by a parabola with vertex at (h, k) as


A translation of a units to the right and b units up will result in


Therefore, the equation of the translated function, g(x) is given by

Translation of graph means to move the graph on the horizontal and vertical axis by shifting it. The equation of the translated function is,

Given information-

The given equation is,

In the given graph the function is at the origin with the coordinate (0,0).

As the power of variable is 2. Thus the function is the quadratic function and the graph is made for the parabola.

What is translation graph?

Translation of graph means to move the graph on the horizontal and vertical axis by shifting it.

Original graph is shifted at (5,2). Thus the translated function has the coordinate (5,2).

The standard form of the parabola can be given as,

Here h,k are the vertex of the parabola.

The transaction is 5 units right and the 2 units up. Thus the equation can be given as,

Hence, the equation of the translated function is,
