Answer:

x=0

x=10

x=24

Step-by-step explanation:

f(x) = -.05x^2 + x +6

The initial value is 6 ( Let x=0 and f(0) = 6)

f(x) = -.05( x^2 -20 x -120)

I plotted the equation and maximum is at x=10 and the zero is at x=25

Which function is increasing at the highest rate?

prisoha [69]

Answer:

Option B: $12x - 6y = -24$

Step-by-step explanation:

A function is said to be increasing if it has a slope greater than 0.

The function with the largest slope has the highest increasing rate.

Here, for the graph in option A, the function is decreasing with increasing $x$ . So, it has a negative slope.

We need to convert equation of option B into standard form and then determine its slope.

The standard form of a straight line is $y = mx + b$ , where $m$ is the slope of the line and $b$ is the y-intercept.

Now, given function is:

$12x - 6y = -24\\ 6y = 12x + 24\\ y = \frac{12}{6}x+\frac{24}{6}\\ y = 2x + 4$

Therefore, the slope is 2.

Option C:

Slope is given as,

$m_{C}=\frac{g(x_{2}-g(x_{1})}{x_{2}-x_{1}} =\frac{-4-(-5)}{2-1}=\frac{-4+5}{1}=1$

Therefore, the slope is 1.

Option D:

Equation of a line with $a$ and $b$ as $x$ and $y$ intercepts is given as,

$\frac{x}{a}+\frac{y}{b}=1$

Here, $a = 8$ and $b = -4$

∴ $\frac{x}{8}+\frac{y}{-4}=1\\ \frac{x-2y}{8}=1\\ x-2y=8\\ 2y=x-8\\y=\frac{1}{2}x-4$

Therefore, the slope is $\frac{1}{2}$ .

Hence, the largest slope is for option B and thereby the highest increasing rate.

The perimeter of a rectangular garden is 62 feet( remember, perimeter= 2l + 2w where l is the length and w is the width). The le

Volgvan

Answer:

w=10 feet

l=21feet

Step-by-step explanation:

let width be x

p=2l+2w

p=62

so we form the equation

l=1+2x

w=x

2(1+2x)+2(x)=62

2+4x+2x=62

6x=60

x=10feet

w=10feet

l=1+2x

l=21feet

An acre measures 4840 square yards. In a city, a lot on which a single-

belka [17]

The lot is <u>9.2% of the an acre.</u>

<u>Given:</u>

Area of an acre = 4840 sq. yards

Area of lot = 40 by 100 ft = $40 ]\times 100 = 4,000 $ ft^{2}$

Convert the area of the lot to feet ( $9 ft^{2} = yd^{2}$ ):

<em>Therefore:</em>

Area of lot = $\frac{4,000}{9} = 444.4 $ yd^{2}$

Percentage occupied by the lot = area of lot / area of acre x 100

$= \frac{444.4}{4840} \times 100\\\= 9.2$

The lot therefore is <u>9.2% of the an acre</u>.
