Answer:
[tex]\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}=3[/tex]
Step-by-step explanation:
We want to evaluate the limit:
[tex]\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}[/tex]
To do so, we can divide everything by x². So:
[tex]=\displaystyle \lim_{x\to \infty}\frac{3+4.5/x^2}{1-1.5/x^2}[/tex]
Now, we can apply direct substitution:
[tex]\Rightarrow \displaystyle \frac{3+4.5/(\infty)^2}{1-1.5/(\infty)^2}[/tex]
Any constant value over infinity tends towards 0. Therefore:
[tex]\displaystyle =\frac{3+0}{1+0}=\frac{3}{1}=3[/tex]
Hence:
[tex]\displaystyle \lim_{x\to \infty}\frac{3x^2+4.5}{x^2-1.5}=3[/tex]
Alternatively, we can simply consider the biggest term of the numerator and the denominator. The term with the strongest influence in the numerator is 3x², and in the denominator it is x². So:
[tex]\displaystyle \Rightarrow \lim_{x\to\infty}\frac{3x^2}{x^2}[/tex]
Simplify:
[tex]\displaystyle =\lim_{x\to\infty}3=3[/tex]
The limit of a constant is simply the constant.
We acquire the same answer.

Step-by-step explanation:
the sum of angle jnm and knp should be 90°
so (7x+2)+(10x+3)=17x+5=90
x=5
so angle knp is 53°
lnk is 90-53=37°
jnm is 37°
jnl js 180-37=143°
jnl is 37+90=127°

There are 185 deer in a state park. The population is increasing at the rate of 16% per year. Enter a
prediction for how long it will take the population to reach 305. If necessary, round your answer to the nearest tenth.
The deer population will reach 305 in approximately _____
years.
Answer:
Approximately 3.4 years more or less
Step-by-step explanation:
If we represent this exponential growth as P=185(1.16)^n where n is the number of years passed and P is the population, then:
P=185(1.16)^n
305=185(1.16)^n
1.65=1.16^n
log₁.₁₆(1.65)=log₁.₁₆(1.16^n)
3.37=n
So the deer population will reach 305 in approximately 3.4 years.

Step-by-step explanation:
Hi there!
What we know:
- Sarah has [tex]11 \frac{1}{4}[/tex] pounds of dog food
- Sarah is dividing this into 3 containers
1) Convert [tex]11 \frac{1}{4}[/tex] into an improper fraction
[tex]11 \frac{1}{4}[/tex]
Multiply the whole number by the denominator
11 × 4 = 44
Add 44 to the numerator
44 + 1 = 45
[tex]\frac{45}{4}[/tex]
2) Divide [tex]\frac{45}{4}[/tex] by 3
[tex]\frac{45}{4} / 3[/tex]
Dividing by a number is the same as multiplying its reciprocal
[tex]= \frac{45}{4} *\frac{1}{3}[/tex]
Multiply the numerators and the denominators
[tex]45*1 = 45\\4*3 = 12[/tex]
[tex]= \frac{45}{12}[/tex]
3) Convert [tex]\frac{45}{12}[/tex] into a mixed number fraction
[tex]\frac{45}{12}[/tex] ⇒ [tex]3\frac{3}{4}[/tex]
Therefore, there will be [tex]3\frac{3}{4}[/tex] pounds of food in each container.

The fifth graders all decided to have a race afterwords Kylie was so thirsty she drank 3 pints of water Valentina was also thirsty so she drank 24 fluid ounces of water who drank more water Kylie or Valentina?
Answer:
Kylie drank more water than Valentina
Step-by-step explanation:
I know that Kylie drank more water than Valentina.
I know this because I took 3 pints and found how many fluid ounces that would equal. 1 pint is equivalent to 16 fluid ounces. So, three pints would be equal to 48 fluid ounces. 16x3=48
Valentina drank 24 fluid ounces.
48 is greater than 24, so Kylie drank more water than Valentina.
A wasp is a flying insect. In wasps, wing length is coded for by a single gene. Two scientists studying wasps hypothesize that short wings are recessive to long wings. Which of the following observations best supports this hypothesis?
Wasps with long wings are less likely to survive.
Wasps with long wings can produce offspring with short wings.
Wasps have wing lengths ranging from very long to very short.
Wasps with short wings prefer to mate with wasps with long wings.
Answer:Wasps with long wings are less likely to survive.

In a survey of 400 people, 65% sald they owned a dog. How many people own a dog?
Answer:
260 people own a dog.
Step-by-step explanation:
Think of the equation as this:
65% of 400 people own a dog.
Since "of" in a math equation means to multiply, replace of with a multiplication sign.
65% * 400 = 260 people own a dog.
To check you're answer, make the fraction 260/400 into a percent.
260/400 = 65%

perform the following Elementary row operation on the augmented Matrix
9514 1404 393
Answer:
[tex]\left[\begin{array}{cc|c}-6&3&-4\\0&-3&11\end{array}\right][/tex]
Step-by-step explanation:
The designated sum can replace either row. Consult your curriculum materials for the intent.
Here, we'll replace row 2 with the sum.
3(2, -2, 5) +(-6, 3, -4) = (3(2)-6, 3(-2)+3, 3(5)-4) = (0, -3, 11)
After the row operation replaces the second row, the augmented matrix is ...
[tex]\left[\begin{array}{cc|c}-6&3&-4\\0&-3&11\end{array}\right][/tex]
Answer:
3(2, -2, 5) +(-6, 3, -4) = (3(2)-6, 3(-2)+3, 3(5)-4) = (0, -3, 11)
After the row operation replaces the second row, the augmented matrix is ...
\begin{gathered}\left[\begin{array}{cc|c}-6&3&-4\\0&-3&11\end{array}\right]\end{gathered}[−603−3−411]
