a) A circle graph inaccurately displays the data because the data is not about parts of a whole.

b) Line graph would best display the data.

A circle is divided into sectors that each represent a component of a whole to create a circle graph, which is a visual representation of data.

An individual data point is connected by a line in a line graph, sometimes referred to as a line plot or a line chart. A line graph shows numerical values over a predetermined period of time.

a) Since circle graphs are designed to depict data consisting of parts of a whole, a data set consisting of temperature variations over the course of a week would be wrongly displayed by one.

b) Since line graphs are the most appropriate for a data set that is tied to time, a line graph would be the most effective way to display the given data.

Answer:

y - 1 = - 3(x + 8)

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 2 ← is in slope- intercept form

with slope m = - 3

• Parallel lines have equal slopes

the equation ofa line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

here m = - 3 and (a, b ) = (- 8, 1 ) , then

y - 1 = - 3( x - (- 8) ) , that is

y - 1 = - 3(x + 8)

The coordinate of Point A is ([tex]\frac{1}{2} ,\frac{\sqrt{3} }{2}[/tex])

Now, According to the question and picture :

Point A is on the unit circle and

The angle between point A and the origin and

The X - axis is [tex]\frac{\pi }{3}[/tex] = 60°.

The radius of the unit circle is 1.

So, the x - coordinate of point A is :

Let x be the total weight of the silver alloy costing $3.50 per ounce and y be the the total weight of the other that costs $7.00 per ounce.

The total weight of the resulting alloy is 30 ounces.

x+y=30x+y=30

Each ounce of the mixture must cost $6.30. The total cost of the resulting silver alloy is:

8 ounces of silver alloy that costs $5.50 per ounce should be mixed with 12 ounces of silver alloy that costs $8.00 per ounce to make a new 20-ounce alloy that costs $7.00 per ounce.

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Let x be the number of ounces of silver alloy which costs $5.50 per ounce and y be the number of ounces of silver alloy that costs $8.00 per ounce.

We have,

x + y = 20

5.50x + 8.00y = 7 × 20

From the first equation, x = 20 - y

Substituting this in the second equation,

5.5 (20 - y) + 8y = 140

(5.5 × 20) - 5.5y + 8y = 140

110 + 2.5y = 140

2.5y = 30

y = 12

x = 20 - y = 20 - 12 = 8

Hence the number of $5.50 cost per ounce silver alloy used is 8 ounces and the other alloy used is 12 ounces.

If you just want to conduct a flyby and aren't planning to stay, it will take you approximately 600 days, and if you want to enter orbit, it will take you about 2,000 days.

Astronomical distances are expressed in terms of a light-year, which is also spelt light year. Its length is approximately 9.46 trillion kilometers, or 5.88 trillion miles.

NASA's Pioneer 10 was the first spacecraft to ever travel across the distance between the Earth and Jupiter. On March 3, 1972, it was launched, and on December 3, 1973, it arrived. There were 640 days of flight time altogether.

However, Pioneer 10 was passing by while en route to study the outer solar system. Before NASA lost communication with it, the spacecraft traveled another 11 years into deep space after approaching the planet at a distance of 130,000 kilometers, where it snapped the first-ever close-up images of Jupiter.

Pioneer 11 launched and touched down one year later. It traveled there in 606 days, flying by Jupiter at a considerably closer distance (21,000 kilometers), and also stopped by Saturn.

The Voyager spacecraft arrived next. Voyager 1 arrived on March 5, 1979, in only 546 days, and Voyager 2 took 688 days.

Consequently, it will take between 550 and 650 days to complete a flyby.

The number of adult tickets sold is 920 , and the number of child tickets sold is 500 .

In the question ,

it is given that

ticket cost for adult = $40

ticket cost for children = $10

and the number of total tickets sold is 1420

let the number of adult tickets sold = x

and the number of children ticket sold = y

According to the question

total tickets sold = number of adult tickets sold+ number of children ticket sold

Substituting the values, we get

x+y = 1420

y = 1420 - x   ...(i)

the total receipts for adult tickets= $40x

the total receipts for children tickets= $10y

given that total amount of tickets sold = $41800

According to the question

40x + 10y = 41800

Substituting the value of y from equation(i) , we get

40x + 10(1420-x) = 41800

40x + 14200 - 10x = 41800

30x + 14200 = 41800

30x = 27600

x = 920

A polynomial is a mathematical equation made up of variables, constants, and exponents that are mixed using addition, subtraction, multiplication, and division operations.

No part of an algebraic expression should be - Variables' square roots. variable powers that are fractional. variable powers that are negative. variables in any fraction's denominator.

Given polynomial, (x + 4) (x - 2) (x + 1)

Keeping the third bracket constant while simplifying the first two results in,

The required time at which the ball reaches a height of 10 ft is 0.5 sec.

Given that,
A ball is thrown into the air with an upward velocity o 12ft/s. The equation for the ball’s height (h) at any time (t) is h (t) =-4t^2+12t+5 find the time(s) at which the ball reaches a height of 10ft.

Here,
Given equation,
h(t) =-4t²+12t+5
For height 10 ft time,
10 = -4t² + 12t + 5
4t² - 12t + 5 = 0
4t² -10t - 2t + 5 = 0
2t(2t - 5) - 1(2t - 5) = 0
(2t-1)(2t -5) = 0

Answer:

Step-by-step explanation:

Ok, a rectangular cube and a Cylinder.

Let's start with the rectangular cube.

SA= 2(lw + lh + wh)

total surface area = 94 cm^2

Now the Surface Area of the of the Cone.

A=2πrh+2πr^2

A=2πrh+2πr^2=2·π·1·5+2·π·1^2≈37.69911 cm^2

Since the cone is standing on top of the rectangular cube, we need to deduct just the area of the circle.

A=πr2=π·12≈3.14159 cm^2

So, 84 cm^2 + 37.69911 cm^2 - 3.14159 cm^2

Sum the quantities:

84 cm^2 + 37.6991 cm^2 - 3.14159 cm^2

Sum the numbers 84 + 37.7 - 3.142 = 118.558:

Answer: Shirt = $7 and Sweater = $18

Step-by-step explanation:

5 Shirts, 3 sweaters = $89   (1)
9 Shirts, 8 sweaters = $207 (2)

1 Shirt = $?

1 Sweater = $?

Shirts = x

sweaters = y

(1) -> 5x + 3y = 89

(2) -> 9x + 8y = 207

(1) * 8 = 40x + 24y = $712

(2) * 3 = 27x + 24y = $621

(1) single out 24y -> 24y = $712 - 40x

put value of 24 y into (2)

(2) -> 27x + $712 - 40x = $621

Now solve

-13x = $-91

remove negative -> 13x = $91

x = $7

So a shirt is $7

And we can put $7 into (1) at the start -> 5(7) + 3(y) = $89

35 + 3y = $89

3y = $54

y = $18

Hence x = $7 and y = $18

So Shirt = $7 and Sweater = $18

According to the associative property of multiplication, the expression to find the cost will be (1.2 × 25) × 4 based on the property and the value is $120.

It should be noted that the associative property of multiplication simply means that when multiplying three numbers, the answer will be the same regardless of how the numbers are grouped.
