Answer:
2715 bacteria
Step-by-step explanation:
This is a simple exponential function. We are given that the initial value is 30, that the value doubles every 4 hours.
Thus, we have our function: [tex]y=30*2^{x/4}[/tex]
Plugging in 26 for x, we get 2715.29004 => 2715 bacteria.

The temperature in a town is 35.2°F during the day and -24.5°F at night. Find the difference in the temperatures
Answer:
[tex]\huge\boxed{\bf\:59.7^{\circ}\:F}[/tex]
Step-by-step explanation:
Temperature during the day = [tex]35.2^{\circ}F[/tex]
Temperature at night = [tex]-24.5^{\circ}F[/tex]
Difference in the temperatures
= Temperature during the day - Temperature at night
= [tex]35.2^{\circ}F - (- 24.5^{\circ}F)\\= 35.2^{\circ}F + 24.5^{\circ}F\\=\boxed{\bf\:59.7^{\circ}F}[/tex]
Difference in the temperatures = 59.7° F

Jim 3 bought 3 hamburgers and 4 orders of french fries for $10.77 before taxes.
Chris went to the same restaurant and bought 4 hamburgers and 2 french fries for
$10.86 before taxes. What is the cost of one hamburger?
Answer:
The cost of one hamburger is $2.19.
Step-by-step explanation:
Let h = cost of a hamburger
f = cost of a french fries
3h + 4f = 10.77-------->3h + 4f = 10.77
4h + 2f = 10.86------->8h + 4f = 21.72
---------------------
5h = 10.95
h = 2.19, f = 1.05

The line graph (C) represents the data representation on the line plot option (C) is correct.
What is a line graph?A line graph is a graph made up of segments of straight lines that connect the depicted data points.
We have data shown in the table:
The data set value 11 repeated two times, so two dots we will see on the line plot.
The data set value 11(1/2) repeated one time, so one dot we will see on the line plot.
The data set value 11(3/4) repeated two times, so two dots we will see on the line plot.
The data set value 12 repeated two times, so two dots we will see on the line plot.
Similarly, we can check for others.
Thus, the line graph (C) represents the data representation on the line plot option (C) is correct.

The number that is given in the statement of this question is x<8.
Algebraic ExpressionAlgebraic expression is a mathematical sentence involving several numbers and letters. These letters are called variables or unknowns, and can be part of equations.
To solve this expression, we will set up the equation as follows, according to the statement.
*a number: x*added to 5: +5*result less than 13: < 13x + 5 < 13
x < 13 - 5
x < 8
Therefore, the unknown number in this equation will be x < 8.

which of the following is the solution to |x|+5≤1?
Isolating the absolute value term, we find
|x| + 5 ≤ 1 ⇒ |x| ≤ -4
However, the absolute value function maps every number x to a non-negative number, so |x| ≤ -4 is impossible and there is no solution to the inequality.

Find f(x) -g(x)
F(x)=-8x^3+1
g(x)=2x^3+6x+7
Answer: -10x³ - 6x - 6
Step-by-step explanation:
f(x) -g(x) means we will subtract g(x) from f(x)
Given:
(-8x³ + 1) - (2x³ + 6x + 7)
Distribute the negative:
-8x³ + 1 - 2x³ - 6x - 7
Combine like terms, simplify:
-10x³ - 6x - 6
f(x) -g(x) is -10x³ - 6x - 6
Answer:
[tex]-10x^{3} -6x-6[/tex]
Step-by-step explanation:
The question is asking us to find f(x) - g(x). In the question it also gives the values of each as:
f(x) = [tex]-8x^{3} +1[/tex]
g(x) = [tex]2x^{3} +6x+7[/tex]
To find the answer, plug both of these values into f(x) - g(x):
([tex]-8x^{3} +1[/tex])-([tex]2x^{3} +6x+7[/tex]) Lets distribute the negative to [tex]2x^{3} +6x+7[/tex].
[tex]-8x^{3} +1[/tex] - [tex]2x^{3}-6x-7[/tex] Combine like terms
[tex]-10x^{3} -6x-6[/tex]
Therefore, the final answer for f(x) - g(x) is equal to [tex]-10x^{3} -6x-6[/tex].

Find the lateral area of the solid figure.
24√3
8√3
12√3
Answer:
Option C. 12√3
Step-by-step explanation:
Lateral area of the solid figure will be = 3×(one lateral side )
Area of a lateral side of the given triangle = (1/2) × (height) × (Base)
Height of an isosceles triangle with a side 4 will be = √(4² - 2²) = √(16-4)= √12 = 2√3
Now area of one lateral side = (1/2)×(2√3)×(4) = 4√3
Therefore lateral area of the solid figure = 3×(4√3) = 12√3
Graph the line with slope 1/2
passing through the point (-4,1).
Answer:
from (-4,1) the line will go up to (-2,2) then (0,3)
Step-by-step explanation:
the slope 1/2 dictates that the line will go up by 1 unit for every 2 units, then we just plot said line from the point given (-4,1) where we go up y by 1 and we go left on x by 2
