Kathleen's gross annual salary is $56,820.

inysia [295]

In general, a maximum of 25% to 30% of one's gross income can be spent on rent. So, according to this lets find out the values.

Given is,

The gross annual salary of Kathleen = $56820

So, her monthly income becomes = $\frac{56820}{12}= 4735$

So, its 25% is = $\frac{25}{100}\times4735$ = 1183.75

And 30% becomes = $\frac{30}{100}\times4735$ = 1420.50

If we take an average of both, as the value will lie between these two figures we get, (1183.75+1420.50)/2 = $1302.12

Hence, this value lies close to $1326. So, the answer will be option B - $1326

What determines whether the graph of an exponential function is increasing or decreasing

rodikova [14]

The sign in the exponent: positive->increases, negative->decreases. Think that a negative sign implies 1/exponential and you'll clearly see the reason.

Could someone help me with this question please!

torisob [31]

X + y = 56 ------------------(1)
x:y = 5:3
x/y = 5/3
3 x = 5 y
so, x = (5/3)y---------------(2)
sub (2) in (1)
x + y = 56
(5/3)y + y = 56
5 y + 3 y = 168
8 y = 168
y = 168 / 8 = 21
x = (5/3) x 21
= 35
the value of x - y = 35 - 21
= 14

Which function has the domain of x≥5 and a range of y≤3?

Salsk061 [2.6K]

The domain of the function are all possible values for variable x and the range of the function are all possible values for the variable y.

Consider the parrent function $y=\sqrt{x}.$ The domain of this function is $x\ge 0,$ the range of this function is $y\ge 0.$

1. Translate this function 5 units to the right. After this translation the function becomes

$y=\sqrt{x-5}.$

2. Reflect previous function about the x-axis, then the expresssion of the new function is

$y=-\sqrt{x-5}.$

The range of the function will be $y\le 0.$

3. Translate the function $y=-\sqrt{x-5}$ 3 units up, then you will get the function

$y=-\sqrt{x-5}+3.$

The domain of this function is $x\ge 5,$ the range of this function is $y\le 3.$

Answer: $y=-\sqrt{x-5}+3.$
