Step-by-step explanation:
two quadratic functions are shown:
which function has lowest minimum value, and what are it's coordinates?
function 1 has the lowest minimum value and it's coordinates are (-1,4)
function 1 has the lowest minimum value and it's coordinates are (0,7)
function 2 has the lowest minimum value and it's coordinates are (-1,7)
function 2 has the lowest minimum value and it's coordinates are (0,3)
Answers
To find the minimum value of function 1, we need to find the vertex. The formula for the x-coordinate of the vertex is -b/2a, which is -1 in this equation. However, to find minimum and maximum values, we need to look at the y-coordinate. f(-1) is 4, which we know is a minimum (rather than a maximum), because the leading coefficient is positive -- so the parabola opens upwards. So, the minimum value of f(x) is 4, and the coordinate is (-1, 4).
From the table, the minimum value of g(x) is 3, and the coordinate is (0, 3).
Therefore, function 2 has the lowest minimum value, with coordinates (0, 3).

a = [tex]3.47 * 10^{-6}[/tex]
b = [tex]4.61 * 10^7[/tex]
c = [tex]5.52*10^7[/tex]
Finding a*b:

Through (-2,4): perpendicular to x=8
(a) The equation of the line in slope-intercept form is_____.
Answers
Answer:
y = 4
Step-by-step explanation:
The line x=8 is a vertical line. The perpendicular line will be horizontal, with a slope of 0. In order for it to go through the given point, the y-intercept must match the y-value of the point. The equation is ...
y = 0x +4 . . . . . slope-intercept form with slope explicitly shown as 0

Calculate the future value of $51,123.21
Answers
Answer:
Option a) $ 82,531.59
Step-by-step explanation:
The Formula for Future value =
Present value (1 + r/n)^nt
From the question
Present value = $51,123.21
Interest rate (r) = 2 3/8 % = 2.375% = 0.02375
n = compounding frequency = compounded daily = using the traditional bankers rule of 30 days = 30 × 12 months = 360
T = Time duration in years = 20 years and 2 months = 20.1667
Future value = $ 51,123.21(1 + 0.02375/260)^20.1667 × 360
Future value = $ 82,531.59
Does coordinate c or coordinate d represent a greater number?
Answers
Answer:
Coordinate d
Step-by-step explanation:
Answer: d is larger
c = -2 and d = -1
====================================================
Explanation:
We have c = -2 as this is the same as the x coordinate of (-2,-1), which is the point directly below (c,5).
The point (3,d) is on the same horizontal level as (-2,-1), so the y coordinates must match up. We therefore have d = -1.
Comparing c = -2 and d = -1, we see that d = -1 is larger as it is to the right of -2.

The total cost f(x), in dollars, for renting a car for a day and driving it x miles is shown: f(x) = 90 + 0.11x What does f(30) represent?
Answers
Answer:
f(30) represents the total cost when the car is driven 30 miles
Step-by-step explanation:
f(30) is the y value when x= 30
Since x represents miles, f(30) is the y value of the function when you drive a car 30 miles, basically how much it will cost.
We solve this by plugging 30 in for x:
f(30)= 90 + 0.11(30)
f(30)= 90 + 3.3
f(30)= 93.3
Thus, renting a car for a day and driving it 30 miles costs $93.30
PLEASE HELP!!!! Emily is making 2 gallons of punch with 4 parts grape juice to 3 parts pineapple juice to 1 part sparkling cider. How many cups of pineapple juice will Emily need?? Hint (1 gallon = 16 cups)
Answers
1 gallon = 16 cups. She is making 2 gallons so needs 32 total cups.
The ratio is 4:3:1
Add the ratios: 4+ 3 + 1 = 8
Divide total cups by total ratio:
32/8 =4
Now multiply that by each portion of the ratio:
Grape juice = 4 x 4 = 16 cups
Pineapple juice = 3x4 = 12 cups
Cider = 1x 4 = 4 cups
She needs 12 cups of pineapple juice.

Gary ordered 30 pizzas for a party. 60% of the pizzas have 12 slices each. The remaining 40% of the pizzas have 10 slices each. Complete the model. Then complete the statements to find the total number of slices of pizza
Answers
2) 12 pizzas and with 10 slices
3) 336 slices of pizza
Statement #1:
Since there are 30 total pizzas then the amount of pizzas with 12 slices is 60% of 30 which is 18. Then you can multiply 18 by 12 to get the amount of slices in the large pizzas with 12 slices:
18 × 12 = 216
-----------------------------------------------------------------------------------------------------------------
60% of the pizzas have 12 slices each. In total, there are 216 slices in these pizzas.
Statement #2
There are 12 remaining pizzas which means that 12 × 10 = 120 is the amount of slices in total of the smaller pizzas.
-----------------------------------------------------------------------------------------------------------------
40% of the pizzas have 10 slices each. In total, there are 120 slices in these pizzas.
Statement #3
To get the total amount of pizzas you simply add both of the previous solutions:
216 + 120 = 336
-----------------------------------------------------------------------------------------------
Altogether, there is a total of 336 slices of pizza.
Yvette likes to increase the distance she runs by 1% each day. If yesterday Yvette ran 10.75km, how much further is she going to run today?
Answers
｡☆✼★ ━━━━━━━━━━━━━━ ☾
The multiplier for 1% would be 1.01
Multiply her distance from yesterday by this value
new distance = 10.75 x 1.01
new distance = 10.8575
I'm assuming you'd want the answer to 2 d.p (however, you can round accordingly if needed otherwise)
Subtract the two values
10.8575 - 10.75 = 0.1075
So, to 2 d.p your answer would be 0.11 km

Camillo used the calculations shown to determine how much he would spend on 2,400 oz of jelly. 48 ounces of jelly costs 3 collars and 84 cents. (StartFraction 48 ounces Over 3 dollars and 84 cents EndFraction) (StartFraction question mark ounces Over 1 dollar EndFraction). Unit price = 13 dollars and 79 cents. 13 dollars and 79 cents (2,400) = 33 thousand and 96 dollars. What is his error? He placed the decimal point incorrectly when dividing. He placed the decimal point incorrectly when multiplying. He wrote the rate incorrectly. He did not make an error.
Answers
Answer:
He wrote the rate incorrectly
Step-by-step explanation:
Camille's calculation
(48/$3.84)(?/s1)
48x/3.84
=$13.79
The correct calculation
(48/$3.84)(?/s1)
48x/3.84
=$12.50
To find the error in Camille's calculation
(48/$3.84)(?/s1)
48x/3.84
=$13.79
We will divide 48 ounces of jelly by $13.79 to get the rate
48/13.79
=$3.48
Therefore, Camille wrote the rate incorrectly by interchanging .84 after the decimal for .48

percentage of bags will the inspector reject? *
Your answer
Answers
Answer: The percentage of bags will the inspector reject = 15.87%
Step-by-step explanation:
Given, The weights of apple bags are normally distributed with a mean of 5 pounds and a standard deviation of 0.25 pound.
i.e. [tex]\mu=5[/tex] and [tex]\sigma=0.25[/tex]
Let X be the weight of any random apple bag.
Since an inspector weighs each bag and rejects all bags that weigh less than 4.75 pounds.
Then, the probability of bags will be rejected = probability that bags weigh less than 4.75 pounds.
[tex]=P(X<4.75)\\\\=P(\dfrac{X-\mu}{\sigma}<\dfrac{4.75-5}{0.25})\\\\=P(z<-1)\ \ \ [z=\dfrac{X-\mu}{\sigma}][/tex]
[tex]=1-P(z<1)\\\\=1-0.8413\ \ \ [\text{By z-value table}]\\\\=0.1587=15.87\%[/tex]
Hence, the percentage of bags will the inspector reject = 15.87%
