Mathematics
1 answer:
ololo11 [35]4 years ago
8 0

Answer:

Interest = $30

Step-by-step explanation:

Formula:

I = prt or I = p · r · t

So:

I = p r t

I = ($500)(.06)(1) <--- Just multiply all of these numbers and you get the final answer of:

Interest = $30.00 or just $30

Answer:

choice 3.)  if k = 3  because then you have 2 domain values  f(3) = 6 and f(3) = 4, but this is not a function.

Step-by-step explanation:

f(3) should equal f(3)  

but f(3) = 6  and then f(3) = 4,  is a no no

Find the maxmium area of a rectangular plot of land which can be enclosed by rope of length 60 metres​
mario62 [17]

Answer:

225 m²

Step-by-step explanation:

If W is the width of the rectangle, and L is the length, then:

60 = 2W + 2L

A = WL

Use the first equation to solve for one of the variables:

30 = W + L

L = 30 − W

Substitute into the second equation:

A = W (30 − W)

A = 30W − W²

This is a parabola, so we can find the vertex using the formula x = -b/(2a).

W = -30 / (2 × -1)

W = 15

Or, we can use calculus:

dA/dW = 30 − 2W

0 = 30 − 2W

W = 15

Solving for L:

L = 30 − W

L = 15

So the maximum area is:

A = WL

A = (15)(15)

A = 225

Write a rule for the linear function in the table. x f(x) –3 –1 0 2 3 5 6 8
Kryger [21]
So the points are
(x,f(x))
(-3,-1)
(0,2)
(3,5)
(6,8)

hmm, find slope

slope betweeen 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
slope betwen (0,2) and (3,5) Is (5-2)/(3-0)=3/3=1

y=mx+b
m=slope
b=y intercept
given slope=1

y=1x+b
find b

input a point
(3,5)
x=3 and y=5
5=1(3)+b
5=3+b
2=b


y=1x+2 is the equaiton

Which mathematical expression is equivalent to the number sentence below
alexandr1967 [171]

Solution :

It says multiply 8 by 12 and then add 9

reading the sentence it is clear that priority is given to multiplication of 8 and 12 , once it is done then we would add 9 .

Let us first write multiplying 8 and 12 which makes it 8 x 12

the result is being add to 12 so we place 8x12 in parenthesis then add 12

which , makes it : ( 8x12) + 9

this matches to now of the given options so it is because multiplication is always given a priority comparing to addition so here parenthesis is not that important .

we can write it without parenthesis like : 8x12 +9

Answer is third option .
