Step-by-step explanation:
Sam the Hummingbird flies at a rate of 2 yards per minute, as modeled by the equation y = 2x. She
increases her rate by 2 yards per minute. Plot two ordered pairs showing the distances she will fly at 1
minutes and 2 minutes, respectively, at her new rate.
Sometimes she may move backwards.
Answer:
See attachment for plot
Step-by-step explanation:
Given
[tex]y =2x[/tex]
[tex]R =+2[/tex] --- increment in the rate
First, we need to model the new rate
A linear equation is:
[tex]y = mx + b[/tex]
Where
[tex]m = rate[/tex]
Compare [tex]y =2x[/tex] and [tex]y = mx + b[/tex]. we have:
[tex]m =2[/tex]
The above represents the previous rate.
The new rate:
[tex]R =+2[/tex]
Rewrite as:
[tex]R = m+2[/tex]
[tex]R = 2+2[/tex]
[tex]R = 4[/tex]
So, the model is:
[tex]y = Rx[/tex]
[tex]y = 4x[/tex]
The plot at 1 and 2 minutes
When [tex]x = 1[/tex]
[tex]y = 4x = 4 * 1 = 4[/tex]
When [tex]x = 2[/tex]
[tex]y = 4x = 4 * 2 = 8[/tex]
So, we have:
[tex](x_1,y_1) =(1,4)[/tex]
[tex](x_2,y_2) =(2,8)[/tex]
Whether she moves backwards or forward, the distance covered remains the same

NASA is conducting an experiment to find out the fraction of people who black out at G forces greater than 6. Step 1 of 2 : Suppose a sample of 502 people is drawn. Of these people, 140 passed out at G forces greater than 6. Using the data, estimate the proportion of people who pass out at more than 6 Gs. Enter your answer as a fraction or a decimal number rounded to three decimal places.
Answer:
The estimate of the proportion of people who pass out at more than 6 Gs is 0.279.
Step-by-step explanation:
Estimate of the proportion of people who pass out at more than 6 Gs.
Number of people who passed out divided by the size of the sample.
We have that:
Sample of 502 people, 140 passed out at G forces greater than 6. So the estimate is:
[tex]p = \frac{140}{502} = 0.279[/tex]
The estimate of the proportion of people who pass out at more than 6 Gs is 0.279.

Answer:
D. 48
Step-by-step explanation:
QP = 16 (given)
LP = ?
Given that P is the centroid of the triangle, therefore:
QP = ⅓(QL) (based on the centroid theorem)
Plug in the value
16 = ⅓(QL)
Multiply both side by 3
3*16 = QL
48 = QL
QL = 48
Find the value of The X
Hi there!
[tex]\large\boxed{x = 3.6}[/tex]
We can use the Pythagorean theorem to solve, where:
CT² = CP² + PT²
Thus:
CT² = 5² + 7²
CT² = 74
CT = √74 = 8.60
To solve for x, we must subtract the radius from CT to solve:
x = CT - 5
8.6 - 5 = 3.6

Answer:
B. A = 119.1 in.²
Step-by-step explanation:
A = area of trapezoid - area of circle
A = ½(b1 + b2)h - πr²
A = [½(27 + 12)(14) - 3.14159(7²)] in.²
A = 119.1 in.²

Andrew Brown's print shop smelled of ink and grease and the sweat of muscular apprentices carrying trays of lead type from the composing table to the printing press. When I was a child, Mr. Brown let me pick out letters and set them in the form. It had been a thrill seeing my words in print.
The printer issued no invitation to me that morning. He was deep in conversation with Mr. Carris as we entered.

How to find the perimeter of a rectangle ,when given the area of the rectangle?
Answer:
120 m
Step-by-step explanation:
Width - x
Length - 5x
x*5x = 500m²
5x² = 500 m²
x²= 500 ÷ 5
x²= 100
x = root 100
x = 10
Therefore width = 10
length 5*10 = 50
Perimeter = 2(l+w)
= 2(10 + 50)
=2*60
=120
a planter is shaped like a right rectangular prism its height, h is 5 4/5 inches. The length, L is 14 1/2 inches ,and its width, W is 3 1/2 inches. When determining of the planter, which statements are correct
Answer:
There appears to be some part of the question missing. Assuming it asks about the volume, the volume is:
Step-by-step explanation:
The volume of a right rectangular prism may be calculated using the formula:
whl, where w is width, h is height and l is length.
In this case it is hlw or (5.8*14.5*3.5) = 294.35 cubic inches.
Answer: 8 ft
Step-by-step explanation:To find the correct answer, use the formula, V=l×w×h. Substitute 48 for the volume, 2 for width, and 3 for height. Then, use a related division equation to find the length.
48 = l × 2 × 3
48 = l × 6, so 48 ÷ 6 = l
8 = l
The length of the planter box is 8 feet.
