Answer:
The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].
Step-by-step explanation:
Let be an exponential function of the form [tex]y = a\cdot b^{x}[/tex] that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex]. Then, we have the following system of equations:
[tex]20 = a\cdot b^{0}[/tex] (1)
[tex]720 = a\cdot b^{2}[/tex] (2)
By dividing (2) by (1), we obtain the value for [tex]b[/tex]:
[tex]\frac{720}{20} = b^{2}[/tex]
[tex]b = \sqrt{\frac{720}{20} }[/tex]
[tex]b = 6[/tex]
And the value for [tex]a[/tex] is found by (1):
[tex]a = 20[/tex]
The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

Answer:
We know
y = 3.5x represents the cost of x pounds of raisins.
Also, cranberries costs $18 per 4 pounds
So, to graph these proportions, we have to find the equation for cranberries, if 4 pounds costs $18, that means 1 pound of cranberries is $4.50, this is the ratio of change of cranberries, using this ratio, we can say that the relation is
y = 4.5x
If you compare, cranberries are more expensive than raisins, the image attached shows both proportion graphed.
Therefore, raisins represent the lower unit price, $3.50 per pound, while cranberries represent the higher unit price, $4.50 per pound.
Answer :
well one line takes the slope of y=3.5x
The cranberries take the slope of Y=4.5x
so raisins have the lowest unit price.

Mrs. Neville is baking five batches of cookies. She will need 2 \frac{1}{2} 2 1 cups of flour for each batch of cookies. If she begins with a 20 cup bag of flour, what is the resulting change in the amount of flour in the bag?
Answer:
12.5 cups used
7.5 cups left
Step-by-step explanation:
Number of batches = 5
Cups of flour per batch = 2 1/2 cups
Initial amount of flour = 20 cup bag
After 5 batches ; number of cup used :
5 * 2 1/2 = 12.5 cups of flour
Change in amount of flour in bag :
(20 cups - 12.5 cups) = 7.5 cups
Sam put 3000 into saving it earned 6% simple interest annually after 6 years how much will Sam have
Answer:
the future value is 4,080
Step-by-step explanation:
The computation of the future value under the simple interest is shown below:
As we know that
Future value = Present value × (1 + rate of interest × time period)
= 3,000 × (1 + 6 × 6%)
= 3,000 × (1 + 0.36)
= 3,000 × 1.36
= 4,080
Hence, the future value is 4,080

a) Jelaskan konsep Alam Melayu.
Answer: The Malay world or Malay realm, is a concept or an expression that has been utilised by different authors and groups over time to denote several different notions, derived from varied interpretations of Malayness, either as a racial category, as a linguistic group or as a political-cultural group. The use of the term 'Malay' in much of the conceptualisation is largely based on the prevalent Malay cultural influence, manifested in particular through the spread of the Malay language in Southeast Asia as observed by different colonial powers during the Age of Discovery.

A certain rectangular prism has a height of 6 m, a length of 5 m, and a width of 4 m. Give the dimensions of a SECOND rectangular prism that will have the same surface area of the first one.
Pls dont look up the question and copy and paste the same answer either
if you do i will report you
if anyone is wondering why im so "pressed' I've had LOTS of issues with arrogant people
Thanks!
PLS DON'T ASK FOR BRAINILEST UNLESS YOU TAKE YOUR TIME AND ACTUALLY DO THE QUESTION PLEASE :((((
Answer:
The surface area is 148
Step-by-step explanation:
Soooo i had to look up how to do it cause i completely forgot how. But once i did, i worked it out.
The formula i got was: A= 2(wl+hl+hw)
W= width h= height l= length
From there i just replaced the corresponding numbers for the letters that represent them. (think of that as like you see someone that you think represents you and you try to replace them, with you. Same here just w/ numbers and letters)
A= 2 [ (4x5) + (6x5) + (6x4) ]
from here you do order of operations starting with what's inside the parentheses. Then you work your way out.
A= 2 [20+ 30+ 24]
A= 2 [74]
Anytime a number is next to parentheses or brackets (which are these: [ ] ) you multiply what is outside them by what's inside them. (for this think about kids. When you seperate them, they try to make more noise. When you seperate numbers, they multiply)
Final answer is
A= 148
if this is wrong i am so, so, so sorry. I hope this helps, and i hope you have an amazing day!! Be tiger fierce! :)
A length of 5.3, a width of 7, and a height of 3. This would give you the same surface area of 148 as the 1st one. Good luck with your studies <3

Please help quick for 25 points with explanations. Any silly and absurd answers will be reported.
Answer:
Note that the tangents to the circles at A and B intersect at a point Z on XY by radical center. Then, since∠ZAB=∠ZQA and ∠ZBA=∠ZQB. ∠AZB+∠AQB=∠AZB+∠ZAB+∠ZBA=180°. ∴ZAQB is cyclic.But if O is the center of w, clearly ZAOB is cyclic with diameter ZO, so ∠ZQO is 90° ⇒Q is the mid-point of XY.Then, by Power of a Point, PY· PX = PA · PB = 15 and it is given that PY+PX = 11. Thus,PX=(11±[tex]\sqrt{61}[/tex])/2. So, PQ=[tex]\frac{\sqrt{61} }{2}[/tex], PQ²=[tex]\frac{61}{4}[/tex]. Thus, the answer is 61+4=65.
Step-by-step explanation:
(urgent please help!!!!)in computing the mean of 8 numbers, a student mistakenly used 17 instead of 25 as one of the numbers and obtained 20 as the mean. find the correct mean.
Answer: 21
Step-by-step explanation:
The student's mean of the 8 numbers is 20; the total of the numbers will be
8 x 20 = 160
If we take out the 17 the total will be 160 - 17 = 143
If we then replace the 17 with 25 the total rises to 168.
168 divided by 8 = 21

z^(21)^(1/5) = z^(21/5)
PLEASE HELP ME I WILL DO ANYTHING!!!
Answer:
x=11
Step-by-step explanation:
the angles shown are supplementary so they will add up to equal 180 so we write the equation 180=5x+10x+15 and solve for x
step 1 combine like terms
180=15x+15
step 2 subtract each side by 15
165=15x
step 3 divide each side by 15
x=11
