Answer:

11.5 and 3.5

Step-by-step explanation:

a+b=15

a-b=8

equating them we get,

2a=23

a=11.5

placing value of b in a-b=8

11.5-b=8

b=3.5

Select the correct word to describe the function. the equation y = startfraction 5 x cubed over 8 endfraction represents functio

balandron [24]

The functions and their descriptions are:

Polynomial: $y = \frac{5x^3}{8}$ and $y = 5x^3 + 8$
Logarithm: $y = 6 + 0.25\ln(x)$
Exponential $y = \frac{18}{1 + 6e^{-0.25x}}$

<h3>How to describe the functions?</h3>

The functions are given as:

$y = \frac{5x^3}{8}$

$y = 6 + 0.25\ln(x)$

$y = \frac{18}{1 + 6e^{-0.25x}}$

$y = 5x^3 + 8$

The functions would be described based on the type of function they represent.

Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.

Kinard's Kennels Inc. ROE is 20%. Their dividend payout ratio is 70%. The last dividend, just paid, was $2.00. If dividends are

bulgar [2K]

Answer:

option C

Step-by-step explanation:

given,

ROE = 20 %

dividend payout ratio = 70%

paid = $ 2.00

value of current stock if required return is 18% = ?

g = (1 - payout ) x ROE

= (1 - 0.7 ) x 20%

= 6 %

dividend = 2 (1 + growth rate)

= 2 x (1 + 0.06) =$ 2.12

as current value of stock

= $\dfrac{D1}{required\ return - growth \ rate}$

= $\dfrac{2.12}{0.18 - 0.06}$

= $17.67

hence, the correct answer is option C

Tatenda takes t seconds to mow a square meter of lawn and Ciara takes c seconds to mow a square meter of lawn. Tatenda mows 700

bagirrra123 [75]

It is given to us that Tatenda takes t seconds to mow a square meter of lawn and Ciara takes c seconds to mow a square meter of lawn.

It is also given to us that Tatenda mows 700 square meters of lawn per week and Ciara mows 750 square meters of lawn per week.

Thus, if Tatenda mows 700 $m^{2}$ in a week, then that means he took $700\times t$ seconds to complete the mowing.

Likewise, if Ciara mows 750 $m^{2}$ in a week, then that means she took $700\times c$ seconds to complete the mowing.

Write a linear function f with the values f(10)=5 and f(2)=-3

Nutka1998 [239]

Answer:

$f(x)=x-5$

Step-by-step explanation:

step 1

Find the slope m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the ordered pairs

(10,5) and (2,-3)

substitute the values

$m=\frac{-3-5}{2-10}$

$m=\frac{-8}{-8}$

$m=1$

step 2

Find the equation of the line in slope intercept form

$f(x)=mx+b$

we have

$m=1$

$point\ (10,5)$

substitute and solve for b

$5=(1)(10)+b$

$5=10+b$

$b=-5$

The linear function is equal to

$f(x)=x-5$
