In the morning, Jasmine biked to her grandma's house in 45 minutes. When she was biking back home in the evening it was foggy and she went 4 mph slower. The trip back took her 1 hour and 10 minutes. How far from her house does her grandmother live?
Answer:
8.4
Step-by-step explanation
Jasmine's grandma's home will be 504 miles away from her home
What is the relation between distance[x] and time[t]?The relation between distance[x] and time [t] is -
[x] = v [t]
where v is the velocity of body.
Given is Jasmine reached her grandma's house in 45 minutes. When she was biking back home in the evening it was foggy and she went 4 mph slower. The trip back took her 1 hour and 10 minutes.
Let her grandma's home be [x] miles away form her house.
Assume that her velocity was [v] mph on her way to grandma's house.
45 = x/v
x = 45v
Her velocity on her way back home would be [v - 4] mph
70 = x/(v - 4)
x = 70(v - 4)
Equating both -
45v = 70(v - 4)
45v = 70v - 280
70v - 45v = 280
25v = 280
v = 11.2 mph
The value of [x] will be -
x = 45 x 11.2 = 504 miles
Therefore, Jasmine's grandma's home will be 504 miles away from her home

Explain: 6I_3n 6n enVision" Geometry * Teaching Resources'
Margaret is incorrect because the given information does not include enough details to determine if the quadrilateral WXYZ is a parallelogram.
To prove that a quadrilateral is a parallelogram, the four sides must be equal in length and the opposite angles must be congruent. The given information does not include any measurements or angles, so it is not possible to determine if the quadrilateral is a parallelogram.
No, 144 inches of tape is not enough to finish the job. The hazard sign has two identical parallelogram-shaped stripes, and each stripe will require more than 144 inches of tape to outline. The area of a parallelogram can be calculated using the formula A = bh, where b is the base and h is the height. In order to determine how much tape is needed to outline the stripes, the base and height of the parallelograms must be known.
There is not enough information to prove that a quadrilateral is a parallelogram, as all four sides must be equal in length and the opposite angles must be congruent. Additionally, 144 inches of tape is not enough to outline the hazard sign's two identical parallelogram-shaped stripes, as the base and height of the parallelograms must be known in order to calculate the area.

Tell whether each function is linear or non-linear. Function A Function B x 0 1 2 3 y 0 1 8 27 y = –x + 5
Answer:
Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the linear function
\(y = mx+b\)
where
m is the slopeb is the y-interceptThe graph of y = mx + b is a straight line. Thus, y = mx + b represents a linear function.
Analzing the function y = –x + 5
Given the linear function
y = –x + 5
comparing with the slope-intercept form of linear equation
The slope m = -1
The y-intercept b = 5
Also, the graph of a linear function is a straight line.
Thus,
The function y = –x + 5 represents a linear function.
Analzing the Table Function
x 0 1 2 3
y 0 1 8 27
In order to identify whether the given table represents the linear function or not, we need to make sure the given function has a constant change x and y.
If there is a constant change in x and y, then it would be a linear Function otherwise it would not represent a linear function.
There is a constant change in x values.
i.e.
1 - 0 = 1
2 - 1 = 1
3 - 2 = 1
But, there is NOT a constant change in y.
i.e.
1 - 0 = 0
8 - 1 = 7
27 - 8 = 19
It is clear that the table does not have a constant change in y-values.
Therefore, the table function does not represent the linear function

For what values of a does lim x→ar(x)=r(a) if r is a rational function?
Choose the correct answer below.
(a) Those values of a for which the denominator of the function r is not zero.
(b) Those values of a for which the numerator of the function r is zero.
(c) Those values of a for which the denominator of the function r is zero.
(d) Those values of a for which the numerator of the function r is not zero.
The correct answer is (d) Those values of a for which the numerator of the function r is not zero.
For a rational function r(x), the limit of r(x) as x approaches a can be determined by evaluating r(a) if the numerator of the function is not zero. This is because when the numerator is not zero, the limit of the function is defined and equal to the value of the function at that point.
However, if the numerator of the function is zero, then further analysis is required to determine the limit. In this case, the limit may be defined or undefined, depending on the behavior of the function as x approaches the point of interest.
In general, for a rational function, the limit exists and is equal to the value of the function at that point if and only if the numerator of the function is not zero at that point.

what are the dimensions of the largest rectangle that can be formed if all the sides (including the partition) sum to 600 units
The dimensions of the largest rectangle that can be formed if all the sides (including the partition) sum to 600 units are 150 units x 150 units. This solution yields an area of 22,500 square units.
To find the dimensions of the largest rectangle that can be formed if all the sides (including the partition) sum to 600 units, we can use the concept of optimization. Let's assume that the rectangle has a length of L and a width of W, with a partition dividing it into two smaller rectangles.
Since all the sides (including the partition) sum to 600 units, we can express this mathematically as:
L + W + 2x = 600
where x represents the length of the partition. Rearranging the equation, we get:
L + W = 600 - 2x
The area of a rectangle is given by the formula A = L x W. To find the largest possible area of the rectangle, we need to maximize this function.
Substituting the above equation into the area formula, we get:
A = (600 - 2x - W) x W
Expanding and simplifying, we get:
A = 600W - 2W^2 - Wx
To find the maximum value of A, we can differentiate it with respect to W and set it equal to zero:
dA/dW = 600 - 4W - x = 0
Solving for W, we get:
W = (600 - x)/4
Substituting this value of W back into the equation for A, we get:
A = (600 - x)^2/16
To maximize A, we need to minimize x. Since x represents the length of the partition, this means that the partition should be as small as possible. Therefore, the largest rectangle that can be formed will be a square with sides of 150 units, and the partition will have a length of zero.

V₁ =
The volume of the larger rectangular prism is 200 cm³.
We have,
Smaller prism.
Length = L = 15 cm
Width = W
Height = H
Volume = 60 cm³
Larger prism.
Length = l = 5 cm
Width = w
Height = h
Volume =
We can see that,
L / l = 15/5 = 3 cm
Now,
To find the volume of the larger rectangular prism, we can set up a proportion based on the ratio of the volumes of the two prisms:
(Volume of the larger prism) / (Volume of the smaller prism)
= (Volume of the larger prism) / (Volume of the smaller prism)
Let's substitute the given values:
(Volume of the larger prism) / 60 cm³ = 200 cm³ / 60 cm³
Cross-multiplying, we have:
(Volume of the larger prism) = (200 cm³ x 60 cm³) / 60 cm³
Simplifying, we get:
(Volume of the larger prism) = 200 cm³
Therefore,
The volume of the larger rectangular prism is 200 cm³.

4) 35° and x° are vertical angles, so they are congruent to each other. Therefore, x°=35°. Since y°+y°+35°=180° since they are all supplementary to each other, then y°=72.5° when solved.
5) A is true. Think of two adjacent angles measured 60° and 30° that are next to each other. They add up to 90° as well.

h→−2limh3+8h+2 First, rewrite the limit by simplifying the function in the limit as much as you can.
The value of the limit is 12.
A limit in mathematics is a point at which a function approaches the output for the specified input values. Calculus and mathematical analysis depend on limits, which are also used to determine integrals, derivatives, and continuity.
It is employed in the analysis process and constantly considers how the function will behave at a specific moment.
We can expand the cube:
(2+h)³ = 8+12h +6h²+ h³
Plugging this in,
lim (h->0)8+12h +6h²+ h³-8 / h = lim (h->0) 12h +6h²+ h³ / h
=> lim (h->0) (12h +6h+ h²) = 12
The idea of the limit of a topological net broadens the definition of the limit of a sequence and relates it to the limit and direct limit in theory category. In general, there are two sorts of integrals: definite integrals and indefinite integrals. The upper limit and lower limit for definite integrals are correctly specified.
