Solve for X in the triangle.

The vertex form of the quadratic function:

[tex]f(x)=a(x-h)^2+k[/tex]

(h, k) - vertex

We have

[tex]y=2(x-3)^2+4[/tex]

h = 3, k = 4

Therefore your answer is:

The vertex of the parabola given by the equation [tex]y = 2(x - 3)^2 + 4[/tex] is at the point (3, 4), which corresponds to answer option C.

The question is asking to identify the vertex of the parabola given by the equation y = 2(x − 3)^2 + 4. In this form, the equation is in vertex form of a parabola, which is [tex]y = a(x - h)^2 + k[/tex], where (h, k) is the vertex of the parabola. Comparing the given equation to the vertex form, we can see that h = 3 and k = 4, hence, the vertex of the parabola is at the point (3, 4). Therefore, the correct answer is C (3, 4).

Answer:

dive below = 5 1/4 ft

Step-by-step explanation:

Dive above water + dive below water = total dive

We know the dive above water is 3 1/2 ft

The total length of the dive is  8 3/4 ft

Substitute in what we know

3 1/2 + dive below = 8 3/4

get a common denominator of 4

3 1/2*2/2 +dive below = 8 3/4

3 2/4 +dive below = 8 3/4

Subtract 3 2/4 from each side

3 2/4 - 3 2/4 +dive below = 8 3/4 - 3 2/4

dive below = 5 1/4 ft

Final answer:

To find out how far below the surface of the water Mya is at the end of her dive, subtract the diving board's height from the total dive length. Convert mixed numbers to improper fractions for easy subtraction, and after calculation, you find that Mya is 5 1/4 feet below the water's surface.

Explanation:

To determine how far below the surface of the water Mya is at the end of the dive, we need to subtract the height of the diving board from the total length of the dive. Mya's dive board is 3 1/2 feet above the water, and the total length of her dive is 8 3/4 feet.

First, convert the mixed numbers to improper fractions to make the subtraction easier. For 3 1/2, multiply 3 (the whole number) by 2 (the denominator) and add 1 (the numerator) to get 7/2. For 8 3/4, multiply 8 by 4 and add 3 to get 35/4.

The fractions are now 7/2 and 35/4. Before subtracting, find a common denominator, which is 4 in this case.

Convert 7/2 to 14/4, so we can subtract it from 35/4.

Subtract 14/4 from 35/4 to find the distance below the water's surface: 35/4 - 14/4 = 21/4.

Finally, convert the improper fraction back to a mixed number. The mixed number for 21/4 is 5 1/4, which means Mya is 5 1/4 feet below the surface of the water at the end of her dive.

Answer:

(-1, -1)

Step-by-step explanation:

Rotating the point (-1, -1) about the origin at -90° will be a 90 degree clockwise rotation.  This will map switch the x- and y-coordinates and negate the x-coordinate:

(x, y)→(y, -x)

(-1, -1) → (-1, 1)

Following this with a 90 degree counter-clockwise rotation will map

(x, y)→(-y, x)

(-1, 1)→(-1, -1)

This is the same point we started with.  Thinking about this logically, if we rotate something 90 degrees clockwise and then follow that with a 90 degree counter-clockwise rotation will put the object back in its original position.

Answer:

The correct option is 3.

Step-by-step explanation:

The coordinates of point P are (4,3).

We have to find the value of

[tex]R_{p,90}\circ R_{o,-90}:(-1,-1)[/tex]

The operations area operated from right to left it means first we have to apply

[tex]R_{o,-90}[/tex], then [tex]R_{p,90}[/tex].

[tex]R_{o,-90}[/tex] means rotation 90 degree clockwise about the origin, it is defined as

[tex](x,y)\rightarrrow (y,-x)[/tex]

[tex](-1,-1)=(-1,1)[/tex]

[tex]R_{p,90}[/tex] means rotation 90 degree counter clockwise about the the point P, it is defined as

[tex](x,y)\rightarrrow (-(y-3)+4,(x-4)+3)[/tex]

[tex](x,y)\rightarrrow (-y+7,x-1)[/tex]

[tex](-1,1)\rightarrrow (-1+7,-1-1)[/tex]

[tex](-1,1)\rightarrrow (6,-2)[/tex]

Therefore the coordinates of image are (6,-2). Option 3 is correct.

To demonstrate that the measure of angle KNQ is equal to the measure of angle MNS, one should use geometric principles to show congruency or similarity between the angles, which could involve establishing congruent triangles or proportional relationships.

To prove that the measure of angle KNQ is equal to the measure of angle MNS, one would need to establish a relationship between the two angles based on geometric principles or congruent triangles. This could involve demonstrating that the angles are corresponding angles of similar triangles, alternate interior angles of a transversal crossing parallel lines, or possibly vertical angles resulting from intersecting lines. Given the information provided, it seems that if one could show that triangles KNQ and MNS are congruent, then by the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) theorem, it would follow that the angles in question are equal.

Applying trigonometry in proving congruency or similarity might be necessary, especially if an equivalence can be drawn from given proportional relationships or if one can establish that angles are congruent through right triangles and the definition of trigonometric ratios.

Final answer:

Brenda will earn $18.75 in simple interest after 18 months on her $500 deposit at a 2.5% annual simple interest rate.

Explanation:

To calculate the simple interest Brenda will earn after 18 months on a $500 deposit at a simple interest rate of 2.5% per year, we can use the simple interest formula:
I = P * r * t, where:

I represents the interest earned,

P is the principal amount (the initial amount of money),

r is the annual interest rate (in decimal form), and

t is the time in years.

First, convert the interest rate from a percentage to a decimal by dividing by 100:

2.5% = 2.5 / 100 = 0.025

Next, since the time is given in months, convert it to years:

18 months = 18 / 12 = 1.5 years

Now, plug the values into the formula:

I = $500 * 0.025 * 1.5

I = $18.75

Therefore, Brenda will earn $18.75 in simple interest after 18 months.

Step-by-step explanation:

Answer: There are 12 pink roses and 7 yellow roses.

Step-by-step explanation:

Since we have given that

Total number of members = 19

Let the number of pink roses be x

Let the number of yellow roses be 19-x

Cost of pink roses be $3

Cost of yellow roses be $2

Total amount spend to buy = $50

According to question,

[tex]3x+(19-x)2=\$50\\\\3x+38-2x=\$50\\\\x+38=\50\\\\x=\$50-\$38\\\\x=\$12[/tex]

Hence, Number of pink roses be 12

and number of yellow roses be

[tex]19-12=7[/tex]

Hence, there are 12 pink roses and 7 yellow roses.

To solve the problem, we set up two equations representing the number of team members and the total cost of roses, respectively. By solving these equations, we find that we should buy 8 pink roses and 11 yellow roses.

This problem is a type of algebraic word problem. We need to find out the number of pink roses and yellow roses to purchase with the total amounts of $50. Here's how we can solve this: Assuming that 'p' stands for pink roses and 'y' stands for yellow roses. We have two equations based on the problem:

By resolving these system of equations, the solution yields that you should buy 8 pink roses and 11 yellow roses.

Answer:

4.36

Step-by-step explanation:

The given expression is

[tex]\sqrt{4.98+2.18\times 7.31}[/tex]

We need to estimate the value of given expression.

First approximate each term of the given expression.

First term : [tex]4.92\approx 5[/tex]

Second term : [tex]2.18\approx 2[/tex]

Third term : [tex]7.31\approx 7[/tex]

The value of given expression after approximation is

[tex]\sqrt{5+2\times 7}[/tex]

[tex]\sqrt{5+14}[/tex]

[tex]\sqrt{19}[/tex]

The approximate value of [tex]\sqrt{19}[/tex] is 4.36.

Therefore, the estimated value of given expression is 4.36.

The estimated square root of 4.92 + 2.18 x 7.31 is between 4 and 5.

To estimate the square root of 4.92 + 2.18 x 7.31, we first calculate the value inside the square root:

4.92 + 2.18 x 7.31 = 4.92 + 15.8678 = 20.7878

Next, we estimate the square root of 20.7878:

Since the square root of 16 is 4, and the square root of 25 is 5, we can estimate that the square root of 20.7878 is between 4 and 5.

Therefore, the estimated square root of 4.92 + 2.18 x 7.31 is between 4 and 5.

The height of the cylinder is 20 meters.

Given,

The formula for the volume of a cylinder is V=πr²h.

The cylinder to the right has an exact value of 180π cubic meters.

Its radius is given as 3 meters in the figure.

We need to find its height.

It is given by:

V = π r² h

Find the volume of the cylinder.

V = π r² h

We have,

V = 180π cubic meters

180π cubic meters = πr²h

Find the height of the cylinder.

We have,

180π cubic meters = πr²h

Divide both sides by π

180 cubic meters = r²h

We have,

r = 3 m

180 cubic meters = 3² square meters x h

180 cubic meters =  9 square meters x h

Divide both sides by 9.

20 meter = h

h = 20 meters

Thus the height of the cylinder is 20 meters.

Answer:

The ball will roll upto 1 m.

Step-by-step explanation:

A 1 kg ball has 10 joules of kinetic energy and starts to roll up a hill.

As along the hill the ball rises up, it loses its kinetic energy. The kinetic energy is converted to potential energy.

According to the law of conservation of energy, the kinetic energy plus the potential energy equals a constant.

Here given kinetic energy as 10 J, so this energy will get converted to potential energy.

We know that, potential energy is

[tex]P.E=m\cdot g\cdot h[/tex]

where,

m is the mass, g is the acceleration due to gravity and h is the height.

Putting the values,

[tex]\Rightarrow 10=1\times 10\times h[/tex]

Answer:

She can use rotation and overlap the two triangles, and if they overlap perfectly/identically, that means they are surely congruent.

Rebecca can prove triangle congruence by applying the rotation property. If she can rotate one triangle to align with the other, maintaining the same shape and size, then the triangles are congruent. Additionally, she can compare corresponding angles and sides to confirm congruence.

Rebecca can use rotations to prove triangle congruence by performing a sequence of rotations, translations, and reflections on one triangle to align it with the other. If she can manipulate one triangle to superimpose it exactly onto the other triangle without changing its shape or size, then they are congruent. She can also use the properties of triangle congruence, such as side-angle-side (SAS), angle-side-angle (ASA), side-side-side (SSS), or angle-angle-side (AAS), to verify their congruence. By demonstrating that the corresponding sides and angles of the two triangles are congruent based on these properties, she can conclusively prove their congruence. This approach ensures that both triangles share identical measurements and configurations, providing geometric evidence for their congruence.
