Answer: The required area of the kitchen floor is 35 sq. units.

Step-by-step explanation: We are given to find the area of the kitchen floor on the floor plan shown in the figure.

We can see that

the kitchen floor in the floor plan is of rectangular shape with length 7 units and width 5 units.

The AREA of a rectangular is equal to the product of its length and breadth.

Therefore, the area of the kitchen floor on the floor plan will be

$A_k=7\times5=35~\textup{sq. units}.$

Thus, the required area of the kitchen floor is 35 sq. units.

If f(x) is an exponential function where f(-1.5) 26 and

mariarad [96]

Answer:

$f(10) = 1147.25$

Step-by-step explanation:

Given

$f(-1.5) = 26$

$f(5.5) = 7$

Required

f(10)

An exponential function is represented as:

$f(x) = ab^x$

$f(-1.5) = 26$ impleies that:

$26 = ab^{-1.5}$ --- (1)

$f(5.5) = 7$ implies that

$7 = ab^{5.5}$ --- (2)

Divide (2) by (1)

$26/7 = ab^{-1.5}/ab^{5.5}$

$3.71429 = b^{-1.5+5.5}$

$3.71429 = b^{4}$

Take 4th root

$b = 1.39$

Substitute $b = 1.39$ in $26 = ab^{-1.5}$

$26 = a * 1.39^{-1.5}$

$26 = a * 0.6102$

Solve for (a)

$a = 26/0.6102$

$a = 42.61$

f(10) is calculated as:

$f(10) = ab^{10}$

$f(10) = 42.61 * 1.39^{10}$

$f(10) = 1147.25$

Tell whether x and y show direct variation 5y=x

Over [174]

I believe x and y in the equation show a direct variation
Direct variation is the relationship between variables such that increase in one variable causes an increase in the other variable and vicevarsa.
In this case, y is directly proportional to x where 5 is a constant

What is the slope of 27y=3x-54?

sergij07 [2.7K]

To identify the slope of the equation given, it would be helpful to write it in the slope-intercept form. It is expressed as y = mx + b where m is the slope. We write it as follows:

<span>27y=3x-54
y = 3x/27 - 54/27
y = x/9 - 2

Therefore, the slope is 1/9. Hope this answers the question. Have a nice day.</span>
