Answer:
[tex](-6, 0)[/tex]
[tex](0, -2.3)[/tex]
[tex](0,\frac{3}{4})[/tex]
Step-by-step explanation:
Solving (1). x-intercept: -6
At x intercept, [tex]y= 0[/tex]
So, the ordered pair is: [tex](-6, 0)[/tex]
Solving (2): y-intercept: -2.3
At y intercept, [tex]x = 0[/tex]
So, the ordered pair is: [tex](0, -2.3)[/tex]
Solving (3): y-intercept: 3/4
At y intercept, [tex]x = 0[/tex]
So, the ordered pair is: [tex](0,\frac{3}{4})[/tex]

Suppose you make coffee and it starts off just too hot to drink, so you put it in the refrigerator temporarily to cool it off. If the original temperature is 190 degrees Fahrenheit and the refrigerator is 36 degrees Fahrenheit, what will the temperature of the coffee be after 3 minutes? (k = 0.12)
Answer:
Step-by-step explanation:
f(x)= 36( 1 - 0.12)^x. F(x)= 36(0.88)^3. f(x)= 95.04 190-95.05 = 94.95 degree.
Because the temperature is going down, we will use (1-0.12) instead of (1+0.12). X=3 because it is what temperature after 3 min. x= time.
I don't understand the question that well, but please don't report me. I will fix it if I can.

Answer:
number 1: {0,-6) number 2: f(-2)=25 number 3: x=±10 number 4:B, or x=-2, x=3
number 5:36 i really hope this helps! have a good day!
Step-by-step explanation:
1: 2x^2+12x +0=0
this is how you set it up
next, you have to find the a,b,and c. This is my personal favorite way of doing this.
a=2 b=12, c=0
you plug it in to the quadratic formula which is
-b±√b^2-4ac/2a
(-12)±√(12)^2-4(2)(0)/2(2)
next you have to simplify
-12±√144-0/4
take the square root of 144
-12±12/4-
then, find the solutions of them
-12+12=0
0/4=0
x=0
we are not done yet
-12-12=-24
-24/4
x=-6
your solutions are 0,-6, which is C
2: it is giving us x, which is -2
plug in -2 to the right side of the equation.
2(-2)^2-4(-2)+9
2(4)-8+9
8-8+9
f(-2)=9
3: this one is fairly simple
x^2=100
take the square root of each side
x=±10
4: you have to replace y for 0 in this one
x^2-x-6=0
all you have to do is factor it out, and it turns into
(x+2)(x-3)
then turn these so they equal 0
x+2=0, x-3=0
x=-2 x=3
your answer would be B
5: this one is fairly simple too
the formula to completing the square is (b/2)^2
you plug in b, which is 12
12/2=6
6^2=36
you would add 36 to each side.
Answer:
7) {0, -6}
1) 25
2) x= ±10
3) x= 3, -2
4) 36

A missing piece of a board game, a circular disk, had an area of 100,608.7, the replacement disks are listed using circumferences, what size circumference should be ordered 1. 1,124.12 mm 2. 0.7 mm 3. 179 mm 4. 1,263,645.774 mm
Answer:
1,124.12 mm
Step-by-step explanation:
Steps to answering this question :
First determine the radius of the circle from the area of the circle
Use the radius determined above to calculate the circumference
Area of a circle = nr²
where r = radius
n = pi = 3.14
100,608.7mm = nr²
to determine the radius, divide both sides of the equation by 3.14
32,040.98726mm = r²
Find the square root of 32,040.98726mm
√32,040.98726mm
r = 179mm
Circumference of a circle = 2nr
2 x 179 x 3.14 = 1,124.12 mm
Delaney is saving money in an account that offers 9% simple interest. She deposits 2000 from her grandmother into the account and makes no additional deposits or withdraws. How many years will it take to grow to 4,700
Answer:
15years
Step-by-step explanation:
Given data
Rate= 9%
Principal= $2000
Final amount= $4700
The simple interest formula is given as
A= P(1+rt)
Substitute
4700=2000(1+0.09*t)
4700= 2000+ 180t
4700-2000= 180t
2700=180t
t= 2700/180
t= 15 years
Hence the time is 15years
Find the surface area of the solid below.
May someone help me out with these problems? Please explain
Answer:
Well you have to solve each problem first to make them the same. Let's do decimals.
a) The square root of 58 is 7.61577310586. Let's round that to 7.62. You can solve this with a calculator.
b) Simply -32.0, since it is a whole negative number.
c) I think there's a typo, 'C' is the second 'b)', which is 49/7. 49 divided by 7 is seven, hence the decimal would be 7.0
d) 2.65 repeated, already a decimal, does not need changed.
e) The square root of 6 is 2.44948974278. Let's round that to 2.45.
f) is just 0. no decimal, just 0.
Now that you have these as the same form of number, you have to put them into one of these categories. The categories can be found below.
Any square root number is irrational. Any never ending number is irrational, like pi, but there are none of those in this situation. So a, and e are all irrational.
Any repeated number, in this case, 2.65 repeated, is a rational number, as is any decimal or fraction, but there are none of these, so d is rational.
-32 is and integer, because it is a negative whole number, so b is an integer.
Whole numbers are any numbers 0+. So f is the only answer that is a whole number.
Natural numbers are any numbers 1+. So c or the second b is a natural number.
Hope this helps :)

(3x - 1)/28 = (x + 7)/24
24(3x - 1) = 28(x + 7)
72x - 24 = 28x + 196
72x - 28x = 196 + 24
44x = 220
x = 220/44

The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost
Answer:
100 bicycle
Step-by-step explanation:
Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.
x is the number of bikes
To minimize the cost, dC/dx = 0
dC/dx = 10x - 1000
Since dC/dx = 0
0 = 10x - 1000
-10x = -1000
x = 1000/10
x = 100
Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

If x increases by 7 in each row of a table of values, and the first differences are all equal to 45.5, then the rate of change is:
a) 6.5
b) 455/7
c) 7/455
d) 318.5
Answer:
b i think
Step-by-step explanation: dont yell just tell me if i got it wrong if i did srry
The rate of change when x increases and the first difference equal to 45.5 is 6.5. Then the correct option is A.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope is given as
[tex]\rm Slope = \dfrac{Rise \ or \ fall}{Run}[/tex]
If x increases by 7 in each row of a table of values and the first differences are all equal to 45.5. Then the rate of change will be given by the slope.
[tex]\rm \\Slope = \dfrac{45.5}{7} = 6.5[/tex]
The rate of change is 6.5.

A storekeeper increased the price of hats by 5%. Write an equation to calculate the increase of the total cost, c, when the price of a hat is p dollars.
Answer:
c = 1.05p
Step-by-step explanation:
the price of the hat before the increase was 100%, after the increase it becomes 100 + 5% = 105%. Representing it as a decimal becomes 1.05p
Let illustrate with an example.
The price of a hat was $100, after the 5% increase. the cost of the hat becomes
100 + (0.05 x 100) = 105
To find the percentage increase
divide 105 by 100 and subtract 1
(105/100) - 1 = 1.05
