Answer:
Step-by-step explanation:
d /d x [ a ^x ]
= d/ d x [ e ^ln ( a ) x ]
= e ^ln ( a ) x ⋅ d /d x [ ln ( a ) x ]
= e ^ln ( a ) x ⋅ ln ( a ) ⋅ d /d x [ x]
= e ^ln (a ) x ln ( a ) ⋅ 1
= ln ( a ) e ^ln ( a ) x
Rewrite/simplify:
= a ^x ln ( a )

2. Which part of the triangle is always directly
opposite the right angle?
Answer:
So BASically
A triangle has 3 sides
One is the hypotenuese
The other is the Base
and the last one is perpendicular
Step-by-step explanation:directly
opposite the right angle is The HYPOTENUESE
For any triangle, the longest side is always opposite the largest angle. The largest angle of a right triangle is always the 90 degree angle. If you had any larger angle, then the triangle wouldn't be a right triangle and instead it would be obtuse.
In a right triangle, the longest side is given the special name hypotenuse. The other sides of a right triangle are called the legs.

Celine is 28, celines age is 4 more than 1/3 of drakes age. How old is drake?
Answer:
Step-by-step explanation:
C = 28
C = 4 + 1/3 D
This means that
28 = 4 + 1/3 D
Subtract 4 from both sides.
24 = 1/3 D
Then to get rid of the fraction, multiply both sides by 3
72 = D
Therefore Drake is 72.

-3 is the point you start
Answer:
y = 1/3x - 3
Step-by-step explanation:
First, find the slope
(3, -2)
(0, -3)
-2-(-3) = 1
3 - 0 = 3
Slope = 1/3
Now, find the y intercept
y = mx + b
-2 = 3 * 1/3 + b
-2 = 1 + b
-3 = b
Rewrite the equation
y = 1/3x - 3

x=-23 and x=32
x=23 and x=-32
x=-2 and x=3
x=2 and x=-3
Answer:
Option A is the correct answer. ; x=-2/3 and x=3/2
Step-by-step explanation:
We have been given that p(x)=(3x+2)(2x−3) is a polynomial.
According to the question's statement, Question asks us to find the zeros of the polynomial.
Let's head to the question in order to get required answer.
p(x)=(3x+2)(2x−3)
=> p(x) = 3x(2x-3) + 2(2x-3)
=> p(x) = 6x² - 9x + 4x - 6
=> p(x) = 6x² - 5x - 6 (This is the standard form for the given polynomial)
Now, We need to find the zeros of the polynomial. So, In order to find its zeros, we need to put p(x).
p(x) = (3x+2)(2x-3)
=> 0 = (3x+2)(2x-3)
=> (3x+2) = 0 or (2x-3) = 0
=> x= -2/3 or x = 3/2
Hence, If p(x)=(3x+2)(2x−3), x = -2/3 & x= 3/2 are the zeros of the polynomial.

John has a soup recipe that calls for two 14.5-ounce cans of chicken broth. The recipe serves 4 people. He wants to increase the recipe to serve it to a party of 28 people. If John buys chicken broth in 1-quart containers, how many containers does he need?
Answer:
6 11/32
Step-by-step explanation:
The two cans of broth used in the recipe total 2·14.5 oz = 29 oz. The number of people John wants to serve is 28/4 = 7 times the number served by one recipe. So, the amount of broth needed is ...
(29 oz)·7 = 203 oz
Each quart container of broth holds 32 oz, so John will need ...
(203 oz)/(32 oz/container) = 6 11/32 containers
John needs 6 11/32 containers of broth.
_____
If John must buy the broth, he must buy 7 containers. he will have 21/32 of a container left over after making his soup.
A builder could get 6 sheets of sheetrock for $9. If he bought 12 sheets, how much money would he have spent? sheets 6 12 money 9 x (12)(6) = 6x 108 = 6x 108 = 6x 6 6 18 = x
Answer:
$18
Step-by-step explanation:
we proceed by first solving for the unit cost of a sheet
then calculate the cost for any number of sheet
We are told that a builder could buy 6 sheets for the cost of $9
this means that one sheet would cost 9/6= $1.5
Now the builder buys 12 sheets
therefore the cost of 12 sheets will be
12*1.5= $18

find the compound interest
on Rs 4000 for 30 months at 10% per annum
Answer:
Rs. 1076.23
Step-by-step explanation:
The compound interest is given by the formula;
A=P(1+r/n )^nt
where
A= amount at the elapse of the period
P= principal amount = Rs=4000
r=rate of interest=10% =0.1
n=number of times the interest is applied per time period= 1
t=number of time periods elapsed = 30 months = 30/12 = 2.5 years
Applying the formula;
A=P(1+r/n )^nt
A=4000( 1+ 0.1/1)^1*2.5
A=4000(1.1)^2.5
A=4000 * 1.2691
A=Rs. 5076.24
Compound interest will be : 5076.24-4000 = Rs. 1076.23

Answer:
640
Step-by-step explanation:
405-45= 360
360+280=640
Answer:
2520 deerStep-by-step explanation:
Given
Tagged deer = 280Caught deer = 405Tagged among caught = 45The ratio of the tagged deer vs total
45 ⇔ 405280 ⇔ xSolving by cross-multiplication
45x = 405*280x = 405*280/45x = 2520So there are about 2520 deer in the forest

Answer:
r = 2.04%
Step-by-step explanation:
r = n{(A/P)^1/nt - 1}
Where,
r = interest rate = ?
n = number of periods = 12
A = future value = $22,960
P = present value = $20,960
t = time = 4 years
r = n{(A/P)^1/nt - 1}
r = 12{(22,960/20,987)^1/12*4 - 1}
= 12{(1.09)^1/48 - 1}
= 12{(1.09)^0.02 - 1}
= 12 (1.0017 - 1)
= 12(0.0017)
= 0.0204
r = 0.0204 × 100
= 2.04%
r = 2.04%
Name an irrational number ( in radical form ) located between 7 and 8. Explain your answer.
Answer:
[tex]\sqrt{59}[/tex]
Step-by-step explanation:
7^2 is 49 and 8^2 is 64, which means the square root of any number between 49 and 64 (exclusive) will be in between 7 and 8, and it's also going to be irrational, because it's not a perfect square.
One number between 49 and 64 is 59, so [tex]\sqrt{59}[/tex] is an irrational number between 7 and 8
