Answer:

Option C is correct.

Step-by-step explanation:

Given: A rhombus. m∠1 = 40°

To find: m∠2

We know that Rhombus is a parallelogram with all equal sides.

⇒ Opposite sides of the Rhombus are parallel.

Then Diagonal act as a traversal for parallel sides.

So, m∠2 = m∠1 ( Alternate Interior Angles are equal )

m∠2 = 40°

Therefore, Option C is correct.

Fred placed 3 strands of bacteria in a petri dish. The bacteria strands double every hour. Write a formula to represent how many

miv72 [106K]

Answer:

C. $f(n) = 3(2)^n$ ; 48 strands of bacteria

Step-by-step explanation:

Fred placed 3 strands of bacteria in a petri dish.

The bacteria strands double every hour.

Formula : y = ab^x

Where a is the initial value

b = growth rate

x = hours

So, A formula to represent how many bacteria strands are present at the nth hour : $f(n)=3(2)^n$

Now we are supposed to find how many strands of bacteria are present at 4 hours.

Substitute the value in the formula :

$f(4)=3(2)^{4}$

f(4)=48

Hence 48 strands of bacteria are present at 4 hours.

The surface area of a triangular pyramid is 1836 ft2.

Archy [21]

A triangular pyramid has 4 triangular faces. If all 4 have the same area, then one of them has area 1/4 of the surface area, 1836. That gives 459 sq ft as the area of one of the triangular faces.

What is the value of r? 5 + r - 2 = 9

Sholpan [36]

5 + r - 2 = 9 add 2 to both sides (because they are like terms)
+ 2 +2
5 + r = 11 subtract 5 from both sides, 5-5 cancels out and 11 - 5 is 6
-5 -5
r = 6

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A(-2, 1)

Point B(1, -1)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(1+2)^2+(-1-1)^2}$
[Distance] [√Radical] (Parenthesis) Add/Subtract: $\displaystyle d = \sqrt{(3)^2+(-2)^2}$
[Distance] [√Radical] Evaluate exponents: $\displaystyle d = \sqrt{9+4}$
[Distance] [√Radical] Add: $\displaystyle d = \sqrt{13}$
[Distance] [√Radical] Evaluate: $\displaystyle d = 3.60555127546$
[Distance] Round: $\displaystyle d \approx 3.6$
