Answer:
a = 15/28
Step-by-step explanation:
As long as the bases are the same, in this case 2, keep the base and add the exponents when multiplying
keep the base and subtract the exponents when dividing
1/4 + 3/7 = 3/28 + 12/28 = 15/28
9). The bacteria in a Petri dish culture are self-duplicating at a rapid pace. The relationship between the elapsed
time, t, in minutes, and the number of bacteria, BC), in the Petri dish is modeled by the following function:
B(O) = 5:35. How many bacteria will make up the culture after 80 minutes? Round to the nearest thousandth it
necessary
Answer:
66.44 MinutesStep-by-step explanation:
The number of Bacteria, B(t) at any time t(in minutes) is given by the function:
We want to determine the time(in minutes) for the culture to achieve 10,000 bacteria.
Therefore:
Divide both sides by 100
good luck
This is for math
Can someone explain why her answer should've been 1/2 if that's correct?
Answer:
8(x-3)+7=2x(4-17)
8(x-3)+7=2x(-13) -13, not 13
8x-24+7=-26x -26x, not 26x
8x-17=-26x
34x=17
x=17/34=1/2 positive 1/2, not -1/2
I need help with this I will mark you if you get it right
Answer:
The area of a rectangle is l x w. So the area of the square is 10 x 10 = 100
The area of a circle is
[tex]\pi \times {r}^{2} [/tex]
The radius of all the circles is 2 inches.
[tex]\pi \times {2}^{2} = \pi \times 4 \: or \: 4\pi[/tex]
There are 4 circles so the area of all four is
[tex]4 \times (4\pi) \: or \: 16\pi[/tex]
To find the area of the shaded part of the square, subtract the area of all the circles, because they are not shaded, from the area of the square, because it is shaded. The difference will be the area of the shaded portion.
[tex]area \: = 100 - 16\pi[/tex]
[tex]area = 100 - 50.6548[/tex]
So the area is approximately 50 Sq in

Given:
Event A : the card has the number 8
Event B : the card is blue
The probability of each events are given as:
P (A) = 1/10
P (B) = 1/4
P(A and B) = 1/10 x 1/4 = 1/40
From thea above information, we can see that the outcome of the event A cannot affect the outcome of the event B.
Therefore, the two events are independent.

I'm also doing the same question rn and I got it correct.Can you show that this is a parallelogram? Explain if you agree or disagree.
Answer:
yes
Step-by-step explanation:
yes because parallelogram are a flat shape with opposite sides parallel and equal in length.
The graph below shows f(x), which represents a parent function, and g(x), which represents a translation of that function.
On a coordinate plane, 2 exponential functions are shown. f (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1. It goes through (negative 3, 8) and crosses the y-axis at (0, 0.5). g (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1. It goes crosses the y-axis at (0, 14) and goes through (1, 5) and (2, 2).
Which statements about the functions are true? Check all that apply.
f(x) = (one-half) Superscript x
g(x) = (one-half) Superscript x + 4 – 2
The ranges of both functions are the same.
The domains of both functions are the same.
The translation from f(x) to g(x) is right 4 units and down 2 units.
Answer:
A. f(x) = (one-half) Superscript x
D. The domains of both functions are the same.
E. The translation from f(x) to g(x) is right 4 units and down 2 units.
The answers are A, D, and E
Step-by-step explanation:
Edge 2020
The statements about the functions are true A. [tex]f(x) = (1/2)^x[/tex]
D. The domains of both functions are the same.
E. The translation from f(x) to g(x) is right 4 units and down 2 units.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).
We are given that On a coordinate plane, 2 exponential functions are shown. f (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1.
When evaluated in zero we have:
f(0) = 2(1/2)^0 = 2
So it crosses through the point (0, 2).
And when evaluated in x = 1, then
f(1) = 2(1/2)^1 = 1
Then it also passes through (1, 1). It goes crosses the y-axis at (0, 14) and goes through (1, 5) and (2, 2).
The answers are A, D, and E

Write the fraction or mixed number as a percent.
1 4/5
Answer:
180%
Step-by-step explanation:
well 1 = 100%.
4/5 can get up to 100 if you multiply by 20/20. so 4/5 x 20/20 is 80/100 or 80%
100% + 80% is 180%

The product of 3 and
increased by 5
Answer AND expaination
The product of a number and 3 increased by 5 is 7 less than twice the number which equation can be used to find this number , n?
its -7
the product of a number and 3: 3n
increased by 5: + 5
7 less than: - 7
twice the number: 2n
That gives us the following:
3n + 5 = 2n - 7
You only asked for the equation, not to actually help you solve for n, for note. If you do, just subtract 2n from both sides, and then subtract 5 from both sides.

-6- — - x
2
Answer:
[tex]-\frac{x^{5} }{2} - x^{2} -6[/tex]
Step-by-step explanation:
[tex]-\frac{x^{5} }{2}[/tex] has the greatest degree and is, therefore, the first term in the equation.
-[tex]x^{2}[/tex] has the second greatest degree and is the second term in the equation.
-6 has the lowest degree so it is the last term.
