Answer:

2 lb

Step-by-step explanation:

1lb = 16 pounds.

Given:

The vertex of a quadratic function is (-5,-1) and it passes through the point (-2,2).

To find:

The vertex and standard form of the quadratic function.

Solution:

The vertex form of a quadratic function is:

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

Where, a is a constant, (h,k) is vertex.

The vertex of a quadratic function is (-5,-1). It means [tex]h=-5,k=-1[/tex].

[tex]f(x)=a(x-(-5))^2+(-1)[/tex]

[tex]f(x)=a(x+5)^2-1[/tex]             ...(i)

The quadratic function passes through the point (-2,2). Putting [tex]x=-2,f(x)=2[/tex] in (i), we get

[tex]2=a(-2+5)^2-1[/tex]

[tex]2+1=a(3)^2[/tex]

[tex]3=9a[/tex]

[tex]\dfrac{1}{3}=a[/tex]

Putting [tex]a=\dfrac{1}{3}[/tex] in (i), we get

[tex]f(x)=\dfrac{1}{3}(x+5)^2-1[/tex]

Therefore, the vertex for of the quadratic function is [tex]f(x)=\dfrac{1}{3}(x+5)^2-1[/tex].

The standard form of a quadratic function is:

[tex]f(x)=Ax^2+Bx+C[/tex]

We have,

[tex]f(x)=\dfrac{1}{3}(x+5)^2-1[/tex]

[tex]f(x)=\dfrac{1}{3}(x^2+10x+25)-1[/tex]

[tex]f(x)=\dfrac{1}{3}x^2+\dfrac{10}{3}x+\dfrac{25}{3}-1[/tex]

[tex]f(x)=\dfrac{1}{3}x^2+\dfrac{10}{3}x+\dfrac{22}{3}[/tex]

Therefore, the standard form of a quadratic function is [tex]f(x)=\dfrac{1}{3}x^2+\dfrac{10}{3}x+\dfrac{22}{3}[/tex].

Answer:

a + [tex]11^{3}[/tex]

or

Answer:

Y=1.50

Step-by-step explanation:

For the graph chart the x as the table says and the y as 1.50 for one then keep adding 1.50 for the others

1) 4x1.50= 6.00

2)5.00/1.50= 3 and 1/3

Answer:

[tex]27a^6b^8 + 63a^5b^8 - 25a^8b^8[/tex]

Step-by-step explanation:

Given

[tex]9a^3b^6(3a^3b^2+7a^2b^2)-(5a^4b^4)^2[/tex]

Required

Simplify

[tex]9a^3b^6(3a^3b^2+7a^2b^2)-(5a^4b^4)^2[/tex]

Open both brackets

[tex]9a^3b^6*3a^3b^2+9a^3b^6*7a^2b^2-5a^4b^4*5a^4b^4[/tex]

This gives

[tex]27a^6b^8 + 63a^5b^8 - 25a^8b^8[/tex]

Answer:

Answer:

I'm not completely sure, but I hope this helps.

Answer:

6.25 years

Step-by-step explanation:

Simple interest = principal x time x interest rate

simple interest = $4,000 - $2,500 = $1,500

1500 = $4,000 x 0.06 x n

1500 = 240n

divide both sides by 240

n = 6.25 years

Answer:

hey,i can answer the question but i cant really see the coordinates

Step-by-step explanation:

Answer:

[tex]2\sqrt{51}[/tex]

Step-by-step explanation:

first, you have to look pythagoras theorem (in picture)

then; x² + 14² = 20²

x² + 196 = 400

x² = 204

x = [tex]\sqrt{204}[/tex] = [tex]2\sqrt{51}[/tex]

Hope this helps ^-^

The length of the unknown side ( x )

We'll have to use pythagoras Theorem.

[tex]\huge\boxed{\sf{Formula: {a}^{2} + {b}^{2} = {c}^{2} }}[/tex]

In this question hypotenuse is given so we'll have to subtract.

Let the unknown be "x"

[tex] {c}^{2} = {a}^{2} - {b}^{2} [/tex]

[tex] {x}^{2} = {20}^{2} - {14}^{2} [/tex]

[tex]x = 204[/tex]

[tex] {x}^{2} = \sqrt{204} [/tex]

[tex]x = 14.28285686[/tex]

[tex]\large\boxed{\sf{x = 14.3 \: (nearest \: tenth)}}[/tex]

Hence, the unknown side of the given triangle is 14.3

Answer:

-152 feet in relation to sea level.

Step-by-step explanation:

If it descends 20 feet per minute, you just multiply the distance by the minutes. So 20x7 and you will get 140. You can't forget that it's already -12 below sea level, so it's 12 feet deeper. It's -152 feet in relation to sea level.

Answer:

hmmmm i saw something about 13?????

Step-by-step explanation:

Answer:

67.5 feet

Step-by-step explanation:

If 1 inch = 9 feet, and the model is 7.5 inches,

you just need to do 7.5 • 9 = 67.5 feet.

OR

7 • 9 = 63 and 1/2 (or .5) • 9 = 4.5

63 + 4.5 = 67.5

*I'm pretty sure it says 1 inch = 9 feet and I'm also basing this off the fact that your work for question 2 is showing the same ratio of 1 inch = 9 feet

Answer:

Step-by-step explanation:

y = opposite

15 = hypotenuse

θ = 57°

therefore we use sin

sinθ = opposite/hypotenuse

sin57° = y/15

y = 15sin(57°)

y = 12,58 units

Step-by-step explanation:

As the problem said, you need to submit a picture of your own work, but I can help nevertheless.

Blank 1:

[tex]\tan 70=\frac{x}{300}\\x=300\tan70 \approx \boxed{824.24}[/tex]

Blank 2:

[tex]\tan 53=\frac{x}{300}\\x=300\tan53 \approx \boxed{398.11}[/tex]

Blank 3:

[tex]300\tan(70)-300\tan(53)\approx\boxed{426.13}[/tex]

Answer:

907.46 ft²

Step-by-step explanation:

Area of a full circle = πr²

Area of a quarter circle would therefore = ¼(πr²)

Where,

r = 34 ft

π = 3.14

Area of quarter circle = ¼(3.14 × 34²) = ¼(3,629.84)

Area of quarter circle = 907.46 ft²

Answer:

C

Show your work:

A perpendicular line has a negative reciprocal slope so 2/3 becomes -3/2, then substitute your point (-6,4) and you get letter C

I used your picture since your Question does not match the picture.

Answer:

y < 1

Step-by-step explanation:

the value of y in the whole part is less than or equal to 1.

Answer:

both ansers are 2.7

Step-by-step explanation:

This is an 45˚, 45˚, 90˚ so the two smaller sides are equal so x=5.4.

the hypotenuse is always sqrt2 times bigger than the smaller sizes so y=[tex]5.4\sqrt{2}[/tex]

Answer:

A; x< 5

Step-by-step explanation:

A simple way to remember the difference between greater than or less than is picturing the symbol as an alligator, the mouth of the alligator, the open end, eats the bigger number. The line under the greater than/ less than symbol means "or equal to". An open circle on a number line means that it's NOT "or equal to", so the answer isn't B or D. On the number line, it shows what x could equal. The arrow falls on 0, I'll use 0 as an example. Is 0 less than 5? Yes. If x could equal 0, that means that x is less than 5.
