Answer:
d1 = 192
d2 = 192
Step-by-step explanation:
step 1
From the imformation given, the distance is the same
so from the table
d1 = 64t
d2 = 48(7-t)
the distance is the same, it means
d1 = d2
therefore we can get the time(t) from here
64t = 48(7-t)
64t = 336 - 48t
collect like terms
64t+48t = 336
112t = 336
t = 336/112
t = 3
substitute t into d1 to get the distance
d1 = 64t
d1 = 64 × 3
d1 = 192
Note, d1 = d2
d2 = 192 too

Identify the inverse operation:r/4
Answer:
The inverse of this expression is the multiplication of 4. Answer: 4r, or 4 times r
Step-by-step explanation:
So first off, multiplication is the inverse of division, therefore, dividing r by 4 is the inverse of multiplying r by 4, so the answer is 4r.

A study is done on the population of a certain fish species in a lake. Suppose that the population size P(1) after years is given by the following exponential
function.
P(t) = 400(1.22)
Find the initial population size.
Does the function represent growth or decay?
O growth O decay
By what percent does the population size change each year?
Answer:
Growth22%Step-by-step explanation:
Given function:
[tex]P(t) = 400(1.22)^{t}[/tex]Initial population size is when t = 0
P(0) = 400(1.22)⁰ = 400(1) = 400The multiple of 1.22 is applied every year, so the ratio of change is:
1.22 = 122% = 100% + 22%This is an exponential growth which represents 22% annual growth.
The function is
y=400(1.22)^tAs per y=ab^x
1.22 is the rate of changeIts growth as it's greater than 1
The percentage increase is
1.22-10.2222%-1+x=-5 please help me

Daniel is baking a cake for Aaron's birthday. The recipe requires 2 1/2 cups of butter, 1/3 cups of brown sugar, and 1/2 cups of baking powder. What is the total amount of ingredients in cups if Daniel makes the cake twice as large as the recipe calls for?
Answer
4 6/12 or 2 3/4 cups of total ingredients
Step-by-step explanation:
There are 2 1/2 cups of butter, 1/3 cups of brown sugar, and 1/2 cups of baking powder.
You'd want to make the denominators the same numbers so it would be easier to divide.
So I multiplied 2 1/2 times 3, 1/3 times 2, and 1/2 times 3.
Then all the numbers would have a denominator of 6. Don't multiply the whole numbers or the numerators. Just the denominator.
''THE NUMBERS'' would change to 2 1/6, 1/6, and 1/6.
If I were to add that it would be 2 3/6.
BUT, You need to multiply by 2 after because it says in the question "How many ingredients in cups will Daniel make the cake twice as large".
What is 2 3/6 times 2 = 4 6/12 total.
If it says to simplify the answer. It would be "'2 3/4 total'' or both answers are correct

Line H is represented by the following equation: 2x + 2y = 8
What is most likely the equation for line K so the set of equations has infinitely many solutions?
x + 2y = 2
x + y = 4
2x + y = 6
x − y = 8
Answer:
B
Step-by-step explanation:
Line H is represented by the equation:
[tex]2x+2y=8[/tex]
And we want to find Line K such that the set of equations has infinitely many solutions.
Remember the three solution sets for linear equations:
If the two are parallel, they have no solutions. If the two are not parallel, they will intersect and thus have only one solution. If the two are the exact same line, then they will have infinitely many solutions.From Line H, we can divide both sides by two. This yields the equivalent equation:
[tex]x+y=4[/tex]
Therefore, the new equation and Line H are the same line. Thus, they will have infinitely many solutions.
The answer is B.
Answer:
b

On Monday the price of one share of Webb company stock was 24.85. By Friday the price was 25.004. By how much did the price change from Monday to Friday ?
Answer:
Change in price = 0.154
Step-by-step explanation:
Given that,
The price on Monday = 24.85
The price on Friday = 25.004
We need to find the change in price from Monday to Friday. It can be calculated as follows :
Change = 25.004 - 24.85
= 0.154
So, the required change in the price is equal to 0.154 .
A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degress. What is the distance between the boat and the shark?
Answer:
81.3 feet
Step-by-step explanation:
A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degrees What is the distance between the boat and the shark?
We solve the above question using Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = Angle of depression = 19°
Distance between the boat and the shark = Adjacent = ? = x
Opposite = 28 feet
Hence:
tan 19 = 28/x
Cross Multiply
tan 19 × x = 28
x = 28/tan 19
x = 81.317904575 feet
Approximately = 81.3 feet
The distance between the boat and the shark is 81.3 feet
Writethecoordinatesoftheverticesafteradilationwithascalefactorof 1 5 ,centeredattheorigin. y x -10 10 -10 10 0 S T U S(5, -10) → S′( , ) T(10, -10) → T′( , ) U(5, 10) → U′( , )
Answer:
The answer is below
Step-by-step explanation:
Write the coordinates of the vertices after a dilation with a scale factor of 1/5 , centered at the origin.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
Dilation is the reduction or enlargement in the size of an object by a scale factor (k). If k > 1, it is an enlargement and if k < 1, it is a reduction. If a point A(x, y) is dilated by a factor k, the new point is A'(kx, ky).
Therefore, if the vertices are dilated with a scale factor of 1/5 , centered at the origin. The new point is:
S(5, -10) → S′(1 , -2) T(10, -10) → T′(2 , -2) U(5, 10) → U′(1 , 2)
Answer:

The graph of linear function g passes through the point (-3,-10) and has a slope of 2.
What is the zero of g.
Answer:
2
Step-by-step explanation:
when x is 2 y = 0.
lets start with writing the function's equation;
it has a slope of 2 so 2x + k = y
given in the question when x = -3, y = -10
so k = -4
y = 2x - 4, 0 = 2x-4 then x = 2
