Answer:
[tex]A(w) = (40 - w) * w[/tex]
Step-by-step explanation:
Given
[tex]P = 80[/tex] ---- perimeter
Required
Write the area as a function of width
The perimeter of a rectangle is:
[tex]P =2(l + w)[/tex]
Where
[tex]l \to length\\ w \to width[/tex]
So, we have:
[tex]80 = 2*(l+w)[/tex]
Divide by 2
[tex]40 = l + w[/tex]
Make l the subject
[tex]l =40 - w[/tex]
The area of a rectangle is:
[tex]A = l * w[/tex]
Substitute: [tex]l =40 - w[/tex]
[tex]A = (40 - w) * w[/tex]
Hence, the function is:
[tex]A(w) = (40 - w) * w[/tex]

= -20 × 6
= -120 (Ans)
Answer:
-120
Step-by-step explanation:
lots of approaches here
suggest saying that there are 3 (odd) number of negative signs
so the answer is negative (-)
5*4 = 20
20*2 = 40
40*3 = 120
we determined that the answer has to be negative
-120

what is the domain of the given function?
{(3,-2), (6, 1), (-1, 4), (5, 9), (-4, 0)}
Answer:
The domain is {3,6,−1,5,−4}
Step-by-step explanation:
Answer:
3,6,-1,5,-4.
Step-by-step explanation:
The domain is the x-value or the first number in the ordered pair. For example: (5,2). The x-value is 5 so that means that the domain is 5. Therefore, for this function, the domain will be 3,6,-1,5,-4.

Find the missing lengths of the sides.
Answer: x = 8, y = 8
Step-by-step explanation: If 8 is already on the exterior of the triangle then this means that every angle should also be 8. But, if this were an equilateral triangle, a triangle with equal sides, then ALL sides would HAVE to be 8. But since I don't have this information (if it's equilateral or not), then I can't be positive about this. Really hope this helps you!
What are the domain and range of the function represented by the table?
Answer:
Doman is always the x-intercept.
And Range is always the y-intercept.
Domain = {-5, 0, 5, 10, 15}
Range = {-1, 0, 1, 2, 3}
So the answer is C.
Is it a function yes or no. 1,2,3,4,5,6.

Find the probability of having 2,3, or 4 successes in five trials of a binomial experiment in which the probability of success is 40%. Round to the nearest tenth of a percent. [ ? ]%
Answer:
65.3%
Step-by-step explanation:
Binomial distribution PMF below (along with a description)
the probabilty of getting 2, 3, or 4 successes in 5 trials is just
p(2)+p(3)+p(4)
p(2)= 5C2*.4²*(1-.4)³ = .3456
p(3)= 5C3*.4³*(1-.4)²= .2304
p(4)= 5C4*.4⁴*(1-.4)=.0768
.3456+.2304+.0768= .6528
there are 6 pink beads and 44 purple beads on olives necklace. What is the ratio of the number of pink beads to the total number beads.
Answer:
Step-by-step explanation:
3:22
Answer:
6/50
Step-by-step explanation:
using probability
pink beads = 6
total beads = 44 + 6
= 50
6/50
3/25
therefore ratio
3 : 25

8 cm =
10 cm =
Part B
Decking costs $1.75 per square foot. How much will it cost to build the deck?
Answer:
27
36 ft
45 ft
$189
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
original dimension = (8 x 9) / 2 = 36
(10 x 9) / 2 = 45
(6 x 9) / 2 = 27
cost of deck = sum of sides x cost per square feet
sum of sides = 36 + 27 + 45 = 108
108 x 1.75 = 189

Find the volume of the sphere.
Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.
Answer:
Volume of a sphere = 4πr³/3
r=10
V = 4πx10³/3
=4000π/3
V= 1333.33π (in terms of pi)
or
V= 4188.79(Nearest Hundredth).

Answer:
d=90 e=27 f=153
Step-by-step explanation:
The angle adjacent to d is 90 degrees. They both add up to 90. 180-90=190. D=90.
E is a vertical angle, congruent to 27.
E=27.
F is a linear pair with 27, which means it's supplementary (adds to 180). 180-27=153.
F=153.
