The formula for the area of a triangle is base*height/2. So lets input the number.

15*40=600/2=300 cm2

Vsevolod [243]

Answer: 610,416 lb

<u>Step-by-step explanation:</u>

Volume of a cylinder (V) = π r² · h

V = π (12)² · 30

= 4320 π

Density = Volume x weight

= 4320 π · 45

= 194,400 π

≈ 610,416

What change(s) should Sylvia make to the equation to find the value of t in the above scenario?

finlep [7]

Answer:

Option (D).

Step-by-step explanation:

Initial population of the deer $P_{0}$ = 4800

Decrease in the population of the deer after every 8 years = $\frac{1}{2}\times (\text{Initial population})$

Decrease in population is an exponential process, so the expression representing population will be,

$P_{t}=P_{0}(1-r)^x$

Where $P_{t}$ is the population after 'x' slots of 8 years.

r = fraction of decrease in the population

x = $\frac{\text{Number of years}}{8}$

By substituting the values of r and x in the expression,

$P_{t}=P_{0}(1-\frac{1}{2})^{\frac{t}{8}}$

$P_{t}=4800(\frac{1}{2})^{\frac{t}{8}}$

Therefore, Sylvia should do few corrections in her expression.

(8) should be replaced by ( $\frac{1}{2}$ ) and $\frac{t}{2}$ should be replaced by $\frac{t}{8}$ .

Option D. will be the answer.

Find the TWO integers whos product is -12 and whose sum is 1<br>m

svetoff [14.1K]

Answer:

$\rm Numbers = 4 \ and \ -3.$

Step-by-step explanation:

Given :-

The sum of two numbers is 1 .

The product of the nos . is 12 .

And we need to find out the numbers. So let us take ,

First number be x

Second number be 1-x .

According to first condition :-

$\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}$

Hence the numbers are 4 and -3.
