Step-by-step explanation:

Look at the graph they gave you. ... At first it looks like an ugly mess.

But look closer.  There are only two lines there that go through the origin,

so one of those is the answer to the question.

Now let's talk about the slope of a line.

-- If the slope of a line is positive, that means it rises as it goes.

  If you walk the graph from left to right, you're climbing.

-- If the slope of a line is negative, that means it falls as it goes.

  If you walk the graph from left to right, you're going down-hill.

The equation they gave you is  [ y = 1/2 x ].

The slope is  1/2 .  That's positive.

The line on the graph slopes up.  To walk it, you have to climb.

In the picture, that can only be line 'c' .

Answer:

The equation they gave you is  [ y = 1/2 x ].

The slope is  1/2.  That's positive.

The line on the graph slopes up.  To walk it, you have to climb.

Answer:

2.5 m/s

Step-by-step explanation:

Matty's speed = 9 km/hr

We need to convert 9 km/hr to m/s

We know that,

1 km = 1000 m

1 hour = 3600 seconds

[tex]v=9\times \dfrac{1000\ m}{3600\ s}\\\\=2.5\ m/s[/tex]

So, Matty jogs with the speed of 2.5 m/s.

Answer:

8 cm

Step-by-step explanation:

A circle with center B and radius 13 cm has three distinct points, F, D and E, on its circumference so that BF and BE and D is on the minor arc FE. Point A is on BF so that DA is perpendicular to BF. The point C is on BE so that ABCD is a rectangle and the distance from C to E is 1cm. Determine the distance from A to F.

Solution:

Since the radius of the circle is 13 cm, hence:

BF = BD = BE = 13 cm.

For line segment BE; BE = BC + CE

BE = BC + CE

13 = BC + 1

BC = 13 - 1

BC = 12 cm

AD = BC = 12 cm (opposite sides of a rectangle are equal to each other)

Triangle ABD, is a right angled triangle because ∠B = 90°. We can use Pythagoras theorem to find AB:

BD² = AB² + AD²

13² = AB² + 12²

169 = AB² + 144

AB² = 169 - 144

AB² = 25

AB = √25 = 5

For line segment BF, we can use the line segment addition postulate to find the distance from A to F. Let x be the distance from A to F:

BF = AB + x

x = BF - AB

x = 13 - 5

x = 8 cm

Step-by-step explanation:

The amount after 3 years will be $ 21,206.6

To understand more, check below explanation.

If the amount P is invested at the rate of r% for n years.

Then amount after n years is computed as;

Given that, Principal = $8,800 , r = 7% and n = 13 years.

                   [tex]A=P(1+\frac{r}{100} )^{n}\\ \\A=8800(1+\frac{7}{100} )^{13} \\\\A=8,800*(\frac{107}{100} )^{13}\\ \\A=\$ 21206.6[/tex]

Hence, the amount after 13 years will be $ 21,206.6

Answer:

Step-by-step explanation:

Cost of the camera at one store,

Down payment = $49

Per month payment = $20

Duration of the payment = 12 months

Total payment to be done = down payment + payments to be done in 12 months

= 49 + (20×12)

= 49 + 240

= $289

Cost of the camera at second store,

Equation describing the payment plan,

y = 15x + 79

Here, x = number of months

y = Total amount to be paid

If x = 12 months

y = (15×12) + 79

y = 180 + 79

y = $259

The camera at the second store is cheaper when the camera is paid off in 12 months because the cost at the first store is $289 and the cost at the second store is $259.

Answer:

$30.00

Step-by-step explanation:

Percentage Markup formula =

Selling price - Cost price/Cost price × 100

From the question:

Cost price = $12.50

Selling price = unknown = x

Percentage Markup = 140%

140% = x - $12.50/$12.50 × 100

140/100 = x - $12.50/$12.50

1.4 = x - $12.50/$12.50

Cross Multiply

1.4($12.50) = x - 312.50

$17.50 = x - $12.50

x = $17.50 + $12.50

x = $30.00

Therefore, the selling price of the purse is $30.00

The best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer

The process of changing the value of one form to another is called conversion. It doesn't affects the value, it simply converts one form to another.

Now it is given that,

Width of a speck of dust = 8.2 x 10⁻⁷ m

Since, 1 kilometer = 1000 meters = 10³ meters

Therefore, 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷ x 10³ kilometer

⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁷⁺³ kilometer

⇒ 8.2 x 10⁻⁷ m = 8.2 x 10⁻⁴ kilometer

Thus, the best way to rewrite the quantity 8.2 x 10^ -7 m, using more appropriate units is D.) 8.2 x 10⁻⁴ kilometer

Answer:

-95

Step-by-step explanation:

The solution is -95

The value of the equation A = -16 + ( -76 ) is A = -95

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = the sum of -19 and -76

On simplifying the expression , we get

A = ( -19 ) + ( -76 )

On simplifying the equation , we get

A = -19 - 76

The value of A = -95

Therefore , the value of A is -95

Hence , the solution of sum of -19 and -76 is -95
