x-------> the length of <span>a rectangular cookie sheet
we know that
area of </span><span>a rectangular cookie sheet=length*width
area of </span>a rectangular cookie sheet=192 in²
area of a rectangular cookie sheet=<span>x² + 4x-----> x*(x+4)
</span><span>Step 1: x² + 4x = 192
</span><span>Step 2: x(x +
4 ) = 192 The length is x. The width is
(x+4)
</span><span>Step 3: x² + 4x = 192=0
we have
</span>x² + 4x = 192
x² + 4x - 192=0
using a graph tool-----> to resolve the second order equation
see the aattached figure
the solution is
x=-16
x=12
(x+16)*(x-12)=0
the length is x=12 in
and the width is-----> (x+4)-----> 12+4----> 16 in
<span>Step 4: (x +
16) (x - 12) = 0
Because the length can't be -
16 the length is 12, and the width is
16</span>
Answer:
D
Step-by-step explanation:
Where the graphs intersect each other is where the solution is. The graphs intersect each other at the points (0,-8) and (4,8). Hope this helps!
F(x) = -2/3x + 2.......f(1/2).....this is basically saying x = 1/2..so sub in 1/2 for x
f(1/2) = -2/3(1/2) + 2
f(1/2) = -1/3 + 2
f(1/2) = -1/3 + 6/3
f(1/2) = 5/3 <===
What is the mode of the following distribution: 63, 75, 75, 79, 82, 82, 84, 84, 84, 84, 91,
AveGali [126]
Answer:
84
Step-by-step explanation:
the mode is the most occurring number in a set of data so because 84 occurs more than any other number it is the answer.
Answer:
56.31 degrees
Step-by-step explanation:
6 = opposite and 4 = adjacent
Tan = opposite over adjacent
Tan(theta)=6/4
=56.30993247
