Answer:
D. m<RST = 2(m<TSU)
Step-by-step explanation:
Given that m<RST = 76°, m<RSU = 48°, and m<TSU = 38°, this implies that:
SU is an angle bisector of angle RST. Thus,
m<RST is twice the measure of <RSU or <TSU.
Therefore, the only option that is correct is:
D. m<RST = 2(m<TSU)

The level of the tide in a harbor changes from 9 1/4 to 4 1/2 above sea level over a period of 3 1/4 h. Whatbis the rate of change in the tide level over this period of time?
Answer:
The answer should be -19/13 per hour. I think, I'm not completely sure.
Step-by-step explanation:
Find the difference of 9 1/4 and 4 1/2
divide by 3 1/4
simplify
4 1/2 - 9 1/4 = -19/4
-19/4 divided by 13/4 = -76/52
-76/52 = -38/26 = -19/13
So the answer should be -19/13 per hour.
The requried rate of change in the tide level over this period of time is 19/13h.
What is the rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
To find the rate of change, we need to divide the change in the tide level by the time elapsed:
Change in tide level = 37/4 - 9/2 = 37 - 18/4 = 19/4
Time elapsed = 13/4 h
Rate of change = Change in tide level ÷ Time elapsed
= 19/4 ÷ 13/4
= 19/13 h
So, the rate of change in the tide level over this period of time is 19/13h.

Step-by-step explanation:

16. Point B(3, 2) translated (right, up) = (-2, 3) will be ...
B' = B + (-2, 3) = (3, 2) +(-2, 3) = (3 -2, 2 +3)
B' = (1, 5)
Note: (x, y) coordinates are (right, up). So, in translation problems it is important to pay attention. Often, the up/down translation is listed before the left/right translation. If you're not paying attention, you may inadvertently reverse the numbers that need to be added to the coordinates to do the translation.
Please help me with this. 3 pieces of gum cost 25 cents. How many pieces of gum can you buy for $1.00?
Answer:
12 pieces
Step-by-step explanation:
There are four 25 cents in a dollar, as a dollar is 100 cents and 100 divided by 25 is four. So as 3 pieces cost 25 cents, multiply 3 by 4 which is 12.
12 pieces of gum would cause $1.00
Answer:
You can get 12 pieces of gum.
Step-by-step explanation:
3 pieces is 25, right? so now to make a dollar you can have four of 25 cents, so multiply, 3x4. You get 12. so you can buy 12 pieces of gum.
a bacteria culture starts with 420 bacteria and grows at a rate proportional to its size. after 6 hours there will be 2520 bacteria.
Population growth rate of the bacterial culture can be expressed as a function of time as N = [tex]e^{kt + C}[/tex]
Step-by-step explanation:
If we assume the number of bacteria at any time (t) is (N). Then, the population of bacterial culture at that time is given by
N = N (t)
It is also given that the rate at which the bacterial culture will grow is proportional to its size. So, the growth rate is given by
dN/dt ∝ N
Removing the sign of proportionality, we get a constant
dN/dt = KN
We get
∫1/N dt = ∫K dt
After integration
ln N = Kt + C
N = [tex]e^{kt + C}[/tex]

Answer:
Yes, because two pairs of corresponding angles in the triangle are congruent. So the answer is A.
Step-by-step explanation:
Corresponding angles is an angle that is in the exact same spot as the other angle and they are congruent to each other which means that they have the same measure/number.
As the picture shows both triangles have all of their angles as the same measures.
Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
The slope of the line shown is 1
Slope of a lineThe formula for calculating the slope of a line is expressed according to the formula
Slope = Rise/Run
Slope = y₂-y₁/x₂-x₁
Using the coordinate point (1,-2) and (3, 0)
Slope = 0+2/3-1
Slope = 2/2
Slope = 1
Hence the slope of the line shown is 1

A family has a hybrid car that gets 40 miles per gallon (mpg) and a pickup truck that gets 17 mpg. They drive at least 500 miles per week using both vehicles but don't want to use more than 20 gallons of gas. Make a recommendation for using each vehicle. Part A Write an expression that represents the total amount of gasoline used. Then write an inequality to show the maximum amount of gasoline that the family wants to use. Define the variables and list any constraints on the variables.
Answer:
[tex]Z=x+y[/tex]
[tex]x+y<20[/tex]
Step-by-step explanation:
Let the gallons of fuel used in the hybrid per week car be [tex]x[/tex] and [tex]y[/tex] be the number of gallons used in the pickup truck per week.
Number of miles driven using both vehicles is at least 500 per week. The inequality that represents the number of miles driven is.
[tex]40x+17y\geq 500[/tex]
The expression of total amount of fuel used would be [tex]Z=x+y[/tex].
Now the sum of the fuels used in both the cars is more than 20 gallons per week. The inequality that represents the total amount of gasoline used is
[tex]x+y<20[/tex]

The value of the polynomial function at p(-5) is 40.
A polynomial is an expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables and is made up of indeterminates (also known as coefficients) and these operations.
In an equation such as the cubic equation, quadratic equation, etc., a polynomial function is a function that only uses positive integer powers or only positive integer exponents of a variable.A polynomial expression is one that can be created from variables and other constants and symbols by adding, multiplying, and raising it to a non-negative integer power. The constants, which represent mathematical objects that can be added to and multiplied, are often numbers, but they can also be any expression that does not contain the indeterminates.The given polynomial function is:
p(x) = x³ + 7x² - 20x -110
or, p(-5) = (-5)³ + 7(-5)² - 20(-5) -110
or, p(-5) = -125 + 175 + 100 - 110
or, p(-5) = 40
So the value of the polynomial function is 40.

-5
-3
-5/6
-1/3
(also i have other questions if you can view the ones on my profile and answer them tysm)
Answer:
The slope is -3.
Step-by-step explanation:
The slope is equal to the change in y over the change in x.
First, we take the two y values, -2 and -8, and subtract the SECOND from the FIRST: -2 - (-8) = -2 + 8 = 6 (= change in y)
Second, we take the two x values, 5 and 7, and subtract the SECOND from the FIRST: 5 - 7 = -2 (= change in x)
Finally, we make a fraction, the change in y over the change in x:
6/-2 = -3
The slope is -3.
