Steve is taller than Jon, but Elijah is taller than Steve. Is Elijah taller than Jon?

we know that

The equation in vertex form of a vertical parabola is of the form

[tex]y=a(x-h)^{2}+k[/tex]

where

[tex](h,k)[/tex] is the vertex of the parabola

and

[tex]x=h[/tex] is the axis of symmetry

if [tex]a > 0[/tex] -----> open upward

if [tex]a < 0[/tex] -----> open downward

In this problem we have

[tex]y=3(x+2)^{2}-3[/tex]

[tex]a=3[/tex]

This is a vertical parabola open upward

The vertex is a minimum

therefore

the answer is

the vertex is the point [tex](-2,-3)[/tex]

the axis of symmetry is [tex]x=-2[/tex]

see the attached figure to better understand the problem

The vertex of the function [tex]y=3{\left({x+2}\right)^2}-3[/tex] is [tex]\boxed{\left({-2,-3}\right)}[/tex].

Further Explanation:

The standard form of the parabola is shown below.

[tex]\boxed{y=a{{\left({x-h}\right)}^2}+k}[/tex]

Here, the parabola has vertex at [tex]\left({h,k}\right)[/tex] and has the symmetry parallel to x-axis and it opens left.

Given:

The quadratic function is [tex]y=3{\left({x+2}\right)^2}-3[/tex].

Calculation:

Compare the [tex]y=3{\left({x+2}\right)^2}-3[/tex] with the general equation of the parabola [tex]\boxed{y=a{{\left({x-h}\right)}^2}+k}[/tex]

.

The value [tex]a[/tex] is [tex]3[/tex], the value of [tex]h[/tex] is [tex]-2[/tex] and the value of [tex]k[/tex] is [tex]-3[/tex].

Therefore, the vertex of the parabola is [tex]\left({-2,-3}\right)[/tex].

The function is symmetric about [tex]x=-2[/tex].

The vertex of the function [tex]y=3{\left({x+2}\right)^2}-3[/tex] is [tex]\boxed{\left({-2,-3}\right)}[/tex].

The number -0.5 divided by itself equals to 1. In general, any number (except zero) divided by itself will always equal to 1.

To find the answer to the given number −0.5/-0.5, you should simply divide the negative number -0.5 by itself (-0.5). Here, a negative number divided by another negative number results in a positive result. Therefore, -0.5/-0.5 equals 1.

In general terms, any non-zero number divided by itself will always equal 1. This is because the division operation is asking 'how many times does this number fit into itself?', and the answer is invariably 'once'.

Answer:

F(1) is not defined

Step-by-step explanation:

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

The probability that a warning would be given is 0.97.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

A hospital has three independent fire alarm systems, with reliabilities of 0.95, 0.97, and 0.99.

This means,

The probability that one alarm will give a warning = 0.95

The probability that one alarm will give a warning = 0.97

The probability that one alarm will give a warning = 0.99

Combining each of them we get,

0.95 + 0.97 + 0.99 = 2.91

Divide by 3.

= 2.91 / 3

= 0.97

This means,

The probability that a warning would be given is 0.97.

Thus,

The probability that a warning would be given is 0.97.

Answer:

Number line with an open circle on 4 and shading to the right.

Explanation:

Call x the number of students that need to sign up so that more than one van is needed to transport them =>

x + 3 > 7

=> x > 7 - 3

=> x > 4

That is the number greater than 4, without including the number 4.

That is the number line is the set of numbers to the right of 4, and the open circle is used to indicate that the number 4 is not included (a closed circle would indicate that the number 4 is included, which is not the case).

Step-by-step explanation:

To find out the number of cups of flour needed for each dozen muffins, you need to divide the total quantity of flour used by the total number of dozens. Therefore, about 2 11/14 cups of flour are required for each dozen muffins.

To find out how many cups of flour are needed for every dozen muffins made, we need to divide the total amount of flour used by the total number of dozens of muffins. The recipe used 312 cups of flour to make 112 dozens of muffins. So, we divide 312 by 112:

312 ÷ 112 = 2.78571428571429

To convert this to a mixed number in simplest form, you can say that approximately 2 11/14 cups of flour are needed for every dozen muffins made.

For every dozen muffins made, the recipe requires [tex]\(2 \frac{11}{14}\)[/tex] cups of flour. This is determined by simplifying the ratio of 312 cups of flour needed for 112 dozen muffins to its simplest form.

To find the cups of flour needed for every dozen muffins, we can set up a ratio between the cups of flour and the number of dozens of muffins.

[tex]\[ \text{Cups of Flour} : \text{Dozens of Muffins} \][/tex]

Given that 112 dozen muffins require 312 cups of flour, the ratio becomes:

[tex]\[ \frac{312 \text{ cups}}{112 \text{ dozens}} \][/tex]

Now, simplify this ratio by dividing both the numerator and the denominator by the greatest common factor, which is 8.

[tex]\[ \frac{39 \text{ cups}}{14 \text{ dozens}} \][/tex]

Now, express this ratio as a mixed number in simplest form. Since 39 and 14 share no common factors other than 1, the mixed number is [tex]\(2 \frac{11}{14}\).[/tex]

Therefore, the answer is [tex]\(2 \frac{11}{14}\)[/tex] cups of flour for every dozen muffins made.

Answer:

A) UY

Step-by-step explanation:

From the given figure, TUYX is one of the side of the rectangular prism and UVYZ  is another side of the rectangular prism.

The both sides are intersecting perpendicular in one edge, that is the line segment UY.

You can see it on the figure.

Therefore, the intersecting line is UY.

Firstly, define a variable `usernum` and let's use 10 as an example. Then, define another variable `summedvalue` and set it as 0 initially. This variable will hold the sum of all odd numbers up to `usernum`.

Next, we start a for loop. This loop will go through each number in the range from 1 to `usernum` inclusive. That's why in the range function we provide `usernum + 1` as the second parameter.

Now, for every number `i` in this range, we check whether it is odd. A number is odd if it gives a remainder of 1 when divided by 2. In other words, we're checking if `i % 2` is not equal to 0 (`i % 2 != 0`).

If the current number `i` is indeed odd, we add it to `summedvalue` (`summedvalue += i`). Then, the loop goes to the next number and the process repeats itself until we've considered all numbers from 1 to `usernum`.

Finally, when the loop ends, the value of `summedvalue` is the sum of all odd numbers from 1 up to (and including) `usernum`. Return this `summedvalue`.

In the case of `usernum = 10`, the odd numbers between 1 to `usernum` are 1, 3, 5, 7, and 9. When you add them together, you get 25. That's why in this case, the result will be 25.

Actually we can directly check if the quotient has equal or one less amount of places than the given number. This can be checked by looking at the number on the biggest place of the dividend, if it is less than the divisor, the answer will have one less digits place. So in this case since the divisor is 4 and the greatest place of the dividend is thousands and the number is 2, so the quotient will be in the hundreds place.

To find the distance between two points (1,5) and (7,9), you can use the distance formula sqrt((x2 - x1)^2 + (y2 - y1)^2). Rounding to the nearest tenth, the distance is approximately 7.2.

To find the distance between two points, we can use the distance formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Using the given points (1,5) and (7,9), we substitute the values into the formula:

d = sqrt((7 - 1)^2 + (9 - 5)^2) = sqrt(36 + 16) = sqrt(52)

Rounding to the nearest tenth, the distance between the two points is approximately 7.2.

A relation that passes through the y-axis twice is not considered a function. A function, by definition, can only output one 'y' value for each unique 'x' value. This relation fails the 'vertical line test' which checks that each 'x' value only connects to a single 'y' value.

In mathematical terms, a relation is a set of ordered pairs, where each first element is related to the second element. A function, on the other hand, is a special type of relation where every input (or 'x' value) corresponds to exactly one output (or 'y' value).

Now, if a relation passes through the y-axis twice, it means that there are two 'y' values for a single 'x' value (which in this case, is zero). This violates the definition of a function. Hence, a relation that passes through the y-axis twice is not a function. It is simply a relation because it doesn't pass the 'vertical line test' (a vertical line passing through more than one point on the graph of a relation means that the relation is not a function).

No Euclidean triangles can have angles that sum to more than 180°, so there are zero triangles with the given measures in Euclidean space; however, exactly one right-angled spherical triangle with these angles exists on a curved surface like a sphere.

The question asks how many triangles exist with the given angle measures of 55°, 45°, and 90°. In Euclidean geometry, the sum of the interior angles of a triangle must equal exactly 180°. Since 55° + 45° + 90° = 190°, which is greater than 180°, no Euclidean triangle can have those angle measures. Therefore, there are zero triangles that can exist with the given angle measures in a flat, two-dimensional Euclidean space.

However, in the context of spherical geometry, triangles can have angles that sum to more than 180°. The provided angles actually describe a right-angled spherical triangle, of which exactly one exists with these measures. This is because on a spherical surface, the sum of the angles of a triangle can be greater than 180° due to the curvature of the space.

Answer:

The numbers are 5 and 20.

Step-by-step explanation:

To find : What are the numbers?

Solution :

Let the one number be 'x'.

The reciprocal is [tex]\frac{1}{x}[/tex]

The another number be 'y'.

The reciprocal is [tex]\frac{1}{y}[/tex]

One number is four times another number.

i.e. [tex]x=4y[/tex] .....(1)

The sum of their reciprocals is [tex]\frac{1}{4}[/tex].

i.e. [tex]\frac{1}{x}+\frac{1}{y}=\frac{1}{4}[/tex] ....(2)

Substitute (1) in (2),

[tex]\frac{1}{4y}+\frac{1}{y}=\frac{1}{4}[/tex]

[tex]\frac{1+4}{4y}=\frac{1}{4}[/tex]

[tex]4y=20[/tex]

[tex]y=5[/tex]

One number is 4y=4(5)=20.

Therefore, the numbers are 5 and 20.
