Which best describes the graph of the function f(x) = 4(1.5)x?
Answer:
B
Step-by-step explanation:
Since this Equation isn't linear because of the squaring, we can eliminate A and C which imply linear functions. Then it's as easy as pluging in zero for the equation and seeing which one works, and you get an answer of B

$36
$54
$81
$99
Answer:
Mike saved 54 dollars

Cat food costs $2.85 for five cans. Ben only wants to buy one can. How much will it cost?
Answer:
$0.57 for each can of cat food
Step-by-step explanation:
2.85/5 = 0.57 giving you the answer
Answer:
it would cost 0.57 cents!
Explanation:
you'd have to divide 2.85 by 5, because if it is that much for 5 cans, and he only wants to buy 1, you'd divide it by 5, to get 0.57 :)

3) if the cost of 1 pen is Rs.10, find the cost of 5 pen
Answer: 5 pens cost Rs.50
Explanation: Since 1 pen costs Rs.10, you will need to multiply the number of pens (1) and the cost of that number of pens (Rs.10) by the amount of pens you must find the cost for (5). Since 10 times 5 is 50, that means that 50 is the cost of 5 pens.

f(x)=2x^2-3x+7 evaluate f(-2)
Answer:
Step-by-step explanation:
Find two linear functions p(x) and q(x) such that (p (f(q(x)))) (x) = x^2 for any x is a member of R?
Let p(x)=kpx+dp and q(x)=kqx+dq than
f(q(x))=−2(kqx+dq)2+3(kqx+dq)−7=−2(kqx)2−4kqx−2d2q+3kqx+3dq−7=−2(kqx)2−kqx−2d2q+3dq−7
p(f(q(x))=−2kp(kqx)2−kpkqx−2kpd2p+3kpdq−7
(p(f(q(x)))(x)=−2kpk2qx3−kpkqx2−x(2kpd2p−3kpdq+7)
So you want:
−2kpk2q=0
and
kpkq=−1
and
2kpd2p−3kpdq+7=0
Now I amfraid this doesn’t work as −2kpk2q=0 that either kp or kq is zero but than their product can’t be anything but 0 not −1 .
Answer: there are no such linear functions.

How would the situation change if the interest on Emma's credit card were compounded annually
rather than monthly, and she didn't make any payments toward the balance?
Select the correct answer from each drop-down menu.
After 4 years, Emma would owe approximately $ M for her original purchase of $300.
It would take around years for her balance to increase from $300 to $450.
Answer:
$525
2.9 years
Step-by-step explanation:
This question is about financial management. It is to be noted that it would take around 2.9 years for her balance to increase from $300 to $450.
What is the calculation for the above?Note that according to the question,
After 4 years, Emma would owe about $525 for her original purchase of $300.
The equation will be:
300 * (1 + x)[tex]^{4}[/tex] = 525 (This is based on the compound interest formula_
⇒ (1+x)[tex]^{4}[/tex] = 7/4 (If we divide both sides by 300)
Hence
x = 0.1502
= 15.02%
When the balance ups from $300 to $450,
We can state that:
300 * ( 1+ 15.02%) [tex]^{y}[/tex] = 450
⇒ Hence, y = 2.9 years.

K(–5, –9); rotation 180° about the origin, translation 3 units left
Answer:
Step-by-step explanation:
Rotate 180 degrees about the origin
X(x,y) ====> X'(-x,-y)
K(-5 , - 9) = K ' (- -5, - - 9)
K' (5,9)
3 Units Left.
y is unchanged.
x becomes x - 3
K'(5,9) ===>k" (5 - 3,9)

Which of the following rational number between 3/7 and 7/8 ?
13/56
19/56
27/56
53/56
Answer:
Step-by-step explanation:
There are two ways to do this. You could use your calculator to find out the decimal numbers that are equivalent to the two given fractions. Then check which one of the givens falls between these two numbers. I wouldn't do it that way -- not when you are told that the answer has 56 as the denominator. So ...
The best way to do it is to change the two givens so that they have a denominator of 56
3/7 = 3*8/7*8 = 24 / 56
7*7 / 7*8 = 49 / 46
So you need a number that is between 49 and 24
There is only one 27 / 56
1. What is the constant of proportionality?
2. What is the equation?
Answer:
y = 1/3a
Step-by-step explanation:
y = ka
1 = 3k
k = 1/3
Confirm constant: (4-1)/(12-3) = 3/9 = 1/3
1 = 3(1/3) + b
1 = 1 + b
b = 0
y = 1/3x or 1/3a
