Step-by-step explanation:

2,700 times 68 divided 653

Sorry about that, here's the answers.

1. expanded form

2. regroup

3.  place value

4. A, C, D. The strategy I used was place value and regrouping. I chose these by using place value to help me understand how to regroup and what each option would sum to.

5. D. Ten thousands place

Answer:

1. Expanded form

2. Regroup

3. Place value

4. A, C, D,

C is correct because a one is equal to 1.

1 x 4,200 = 4,200. Therefore 4,200 ones is equal to 4,200. D is correct because a ten is equal to 10. 10 x 420 = 4,200. Therefore, 420 tens is equal to 4,200. A is the same as the rest but with hundreds.

5. A

Step-by-step explanation:

1. Expanded form refers to when a number is separated by place values. Like 555,555 being turned into 500,000 + 50,000 + 5,000 + 500 + 50 + 5.

2. Regrouping is separating number by places values to do an equation like subtraction. For example, 5 tens - two ones.

3. Place values refers to a digit in a number like the 1 in 2,134 is in the hundreds place and the 5 in 5,677 is the thousands place.

4. My answer explains it.

5. A is correct as the 2 in 321,705 is 20,000 while the 2 in 32,571 is 2,000. 20,000 is 10 times larger than 2,000. So the answer is 10.

Given:

Giant panda population in 2014 = 1864

The giant panda population in China is increasing at a rate of 1.5% each year.

To find:

The function that models the panda population since 2014.

Solution:

Since population of giant panda is increasing, therefore the function is the exponential growth model.

The general exponential growth model is:

[tex]P(t)=P_0(1+r)^t[/tex]

Where, [tex]P_0[/tex] is the initial population, r is the growth rate in decimal and t is the time period.

Putting [tex]P_0=1864,r=0.015[/tex], we get

[tex]P(t)=1864(1+0.015)^t[/tex]

[tex]P(t)=1864(1.015)^t[/tex]

Where, t is the number of years since 2014.

Therefore, the required exponential growth model is [tex]P(t)=1864(1.015)^t[/tex].

Step-by-step explanation:

11.26 is the correct answer

Answer:

No.

Step-by-step explanation:

If n=3 the only thing you get is 6, which is not more than 6.

Answer:

93312

Step-by-step explanation:

We can use the geometric sequence formula

a= a1(r)^n-1

Substitute:

a=2(6)n^1

a=2 *6^n* 1/6

a=6^n*1/3

Substitute "7" for n:

a(7)=6^(7)*1/3

a(7)=93,312

Answer:

Total amount pay by Ben = $82.27 (Approx.)

Step-by-step explanation:

Given:

2 Shirts = $16 each

3 pairs of socks = $2.50 each

1 pair of jeans = $37.75 each

Sales tax = 6.5%

Find:

Total amount pay by Ben

Computation:

Total amount for shirts = 2 x 16

Total amount for shirts = $32

Total amount for socks = 3 x 2.50

Total amount for shirts = $7.50

Total amount before tax = $32 + $7.50 + $37.75

Total amount before tax = $77.25

Total amount pay by Ben = Total amount before tax[1+tax]

Total amount pay by Ben = 77.25[1+6.5%]

Total amount pay by Ben = $82.27 (Approx.)

Answer:

I'll do the dilation for the first point and you will see the answer (please verify the second point)

Step-by-step explanation:

The dilation about the origin is straightforward, you just multiply the coordinates of each point by the scale factor.

so the dilated point for (-4,-4) is -4x3.5= -14 which is the same for the y coordinate.

so the dilated point for (-4,-4) is (-14, -14)

Please verify by computing the dilated point for (-6,4)

Answer:

70%

Step-by-step explanation:

An easy way to figure this out is like this: Percentage is out of 100 so that would mean 30% is equal to 30/100. Basically, all you need to do is subtract 100-30 and convert to a percent (just add the percent sign). Boom! 70% is your answer!!!!!!! :)

Answer:

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

Step-by-step explanation:

The sum of interior angles of a triangle = 180°

From the above question, one of the angles = 60°

The value for the two other interior angles = 180° - 60° = 120°

Hence, the following options could be the values of x and y is given as x + y = 120

Therefore,

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

Answer:

option C is most accurate cause it has a longer neck thus helping in more flexible movements

Step-by-step explanation:

Isabela Island, dome-shaped shell.

It seems the neck of this tortoise is the shortest, therefore they cannot reach high places.

Just my guess though.

Answer:

y = 1/4 (x-4)² - 7

Step-by-step explanation:

Point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6

√(x-4)²+(y- -8)² = √(y- -6)²

(x-4)² + (y+8)² = (y+6)²

(y+8)² - (y+6)² = (x-4)²

(y²+16y+64) - (y²+12y+36) = (x-4)²

y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²

4y = (x-4)² - 28

y = 1/4 (x-4)² - 7

standard formula of parabola: y = a(x-h)² + k      (h,k): vertex (4,-7)

The value of equation of parabola is,

⇒ y = 1/4 (x-4)² - 7

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.

Now,

Let a point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6

Hence, We can formulate;

⇒ √(x-4)²+(y- (-8))² = √(y- (-6))²

⇒ (x-4)² + (y+8)² = (y+6)²

⇒ (y+8)² - (y+6)² = (x-4)²

⇒ (y²+16y+64) - (y²+12y+36) = (x-4)²

⇒ y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²

⇒ 4y = (x-4)² - 28

⇒ y = 1/4 (x-4)² - 7

Thus, The value of equation of parabola is,

⇒ y = 1/4 (x-4)² - 7

Step-by-step explanation:

im pretty sure this answers your question

The standard form of the vertex form equation is y = 2x² - 12x + 17

The vertex form of a quadratic equation is represented as:

y = a(x - h)² + k

Using the above form, the quadratic equation can be represented as:

y = 2(x - 3)² + 1

Expand

y = 2(x² - 6x + 9) - 1

Further expand

y = 2x² - 12x + 18 - 1

Evaluate the like terms

y = 2x² - 12x + 17

Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17
