A field with an area of 2880 ft^2 has the shape of a rectangle, whose length is 12 ft larger than its width. Find the dimensions

tiny-mole [99]

ANSWER

w=48,l=60

EXPLANATION

Let the width of the field be, w , then,

the length of the field will be:

$l = 12 + w$

The area of a rectangle is

$Area = lw$

This implies that:

$w(12 + w) = 2880$

Expand

${w}^{2} + 12w = 2880$

${w}^{2} + 12w - 2880 = 0$

$(x + 60)(x - 48) = 0$

This implies that,

$w = - 60 \: w = 48$

The dimensions are positive, the width is 48 and the length is 12+48=60

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation PLEASE ANSWER THUS PLEASE

exis [7]

Answer:

$(-9,16]$

Step-by-step explanation:

we know that

The domain of x is equal to the interval--------> $(-2,3]$

$-2< x \leq 3$

All real numbers greater than $-2$ and less than or equal to $3$

Let

$y=5x+1$

For $x=3$

$y=5x+1\\y=5(3)+1=16$

For $x>-2$

$y >5(-2)+1\\y > -9$

The range of the function is the interval--------> $(-9,16]$

The variable y varies directly with x . If x=2 and y = −7, find y when x = −6.

suter [353]

Answer:

Step-by-step explanation:

X=2

Y=-7

Then if x is -6 u have to find what times 2 is -6 Which is -3.

so -7 x -3 is 21. Y is 21

If m(x)=x+5/x-1 and n(x) = x – 3, which function has the same domain as (m.n)(x)

meriva

Answer:

The domain of function (m.n)x is same as domain of function m(x).

Step-by-step explanation:

Domain: Any set of input values for which the function is defined and valid.

m(x)=x+5/x-1

Domain of m(x) is x>1 or x<1, x≠1, because if x=1 the function will be undefined.

n(x) = x – 3

Domain of x -3 is -∞<x<∞ i.e all real numbers

(m.n)x = (x+5/x-1)(x-3)

= (x+5)(x-3)/x-1

The Domain of (m.n)x is x<1 or x>1 or x≠1 because the function is undefined for x=1

So, the domain of function (m.n)x is same as domain of function m(x).
