Answer:

$\huge \boxed{B=\frac{d - 3f^2}{5M}}$

$\rule[225]{225}{2}$

Step-by-step explanation:

$d - 3f^2 = 5BM$

Dividing both sides by 5M.

$\displaystyle \frac{d - 3f^2}{5M} =\frac{5BM}{5M}$

$\displaystyle \frac{d - 3f^2}{5M} =B$

$\rule[225]{225}{2}$

Veseljchak [2.6K]

Plus means addition and square root means √

3 plus the square root of negative 16: 3 + √-16

Minus means subtraction and square root means √

6 minus the square root of negative 64: 6 - √-64

Its asking you to multiply both quantities.

(3 + √-16) * (6 - √-64)

A certain forest covers an area of 2100 km^2. Suppose that each year this area decreases by 5.25%. What will the area be after 6

Neko [114]

Answer:

The area after 6 years is $1519.49km^2$

Step-by-step explanation:

Given

$a = 2100$ --- Initial Value

$r = 5.25\%$ --- Rate

Required

Determine the area after 6 years

Because the area reduces,, the following formula will be used to solve the question.

$y = a*(1 - r)^t$

Here

$t = 6$

So, we have:

$y = 2100*(1 - 5.25\%)^6$

Convert percentage to decimal

$y = 2100*(1 - 0.0525)^6$

$y = 2100*(0.9475)^6$

$y = 1519.47866516$

$y = 1519.49$ -- approximated

The area after 6 years is $1519.49km^2$

A dinosaur fossil is 93,550,000 years old. How can you express this age in scientific notation

garik1379 [7]

1. 9.355 × $10^{7}$ can be used to express the age of the dinosaur fossil.

Step-by-step explanation:

Step 1; To determine which value is the closest to 93,550,000 we must calculate how much the 4 options equal. If there are decimals in the number, they are moved from the decimal part of the number to the integer part with every power of 10 i.e. 2.4 × 10 = 24, 2.44 × 10² = 244.

Step 2; Now we determine how much the 4 options equal.

1. 9.355 × $10^{7}$ = 93,550,000.

2. 9 × $10^{7}$ = 90,000,000.

3. 9.36 × $10^{7}$ = 93,600,000.

4. 9.3 × $10^{7}$ = 93,000,000.

Out of the four options, option 1 equals the value of 93,550,000. So option 1 can be used to express the age with the highest precision.
