Simple,
using
find your slope...
thus, 10=m (slope)
Now, using y=mx+b to find your equation, plug in what you know...
Use any of the 2 coordinates.. (1,5)
5= 10(1)+b
5=10+b
-10 -10
-5=b
Thus, the equation to your line is...
y=10x-5.
Answer:
a) 2x^4 + 8x^3 + x^2 + 3x
b) evaluate this polynomial at x = 10
Step-by-step explanation:
Hi!
a)
The product of a sum is the sum of the products, having said this:
b)
We can use the result from part a and consider x = 10.
First lets take the first polynomial
Knowing that every number (excepting probably 0, which could be undefined for some or 1 for others) to the power of 0 is one:
Which is the initial number
Now lets conisder the product of the polynomial times x and evaluate it at x=10:
We can now see that teh rule is treu because we can see the whole number as a sum of numbers from 0 to 9 multiplied by a power of 10, and when it is multiplied by 10, each power increases by one, and at the end, the final result is adding a zero at the end
We will use ratio and proportion between the inclined sides with its corresponding horizontal bases. Then we could determine for the value of segment AQ.
PA/SB = AQ/BR
32/30 = AQ/24
AQ = 25.6 yd
Since what is asked is segment PQ,
PQ = PA + AQ
PQ = 32 + 25.6
PQ = 57.6 yards
Answer:
D and E
Step-by-step explanation:
Both of these answers are still equal to the fraction -2/5.
We have that
<span>A).Formulate a recursive sequence modeling the number of grams after n hours.
a(n) = 0.75*a(n-1)
</span>B) .Use the model to calculate the amount of contaminants after the third hour of the experiment.
<span> for the first hour
</span>a(1) = 0.75*a(0)
<span>a0=400 g
a1=(3/4)400 = 300 g
for the second hour
</span>a(2) = 0.75*a(1)
<span>a1=300 g
a2=(3/4)300 = 900/4 g
for the third hour
</span>a(3) = 0.75*a(2)
<span>a2=900/4 g
(3/4)900/4 = 2700/16 = 168.75 g
the answer is </span>168.75 g
