Step-by-step explanation:

Answer:

The distance is 8.4853

Step-by-step explanation:

Input Data :

Point 1 (xA, yA) = (0, -1)

Point 2 (xB, yB) = (6, 5)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points = √(xB − xA) ^ 2 + (yB − yA) ^ 2

Solution :

Distance between two points = √ (6 − 0)^2 + (5− −1) ^ 2

= √6^2 + 6^2

= √36 + 36

= √72

= 8.4853

Distance between points (0, -1) and (6, 5) is 8.4853

hope this helps and is right :)

Answer:

Answer:

$240.92

Step-by-step explanation:

From the question,

The distance traveled by the truck is directly proportional to the amount of petrol used.

I.e,

d ∝ v............... Equation 1

d = kv

d/v = k

d₁/v₁ = d₂/v₂............. Equation 2

Where d₁ and d₂ are initial and final distance respectively, v₁ and v₂ are initial and final amount of petrol used respectively.

Given: d₁ = 450 km, d₂ = 1050 km, v₁ = 35 liters

Substitute into equation 2 and solve for v₂

450/35 = 1050/v₂

v₂ = (1050×35)/450

v₂ = 36750/450

v₂ = 81.67 Liters.

If a liter of petrol cost $2.95,

Then,

81.67 liters will cost (81.67×$2.95) = $240.92

Step-by-step explanation:

The solid, blue line is the graph of a function. The dotted, blue line is not a function.

Answer:

D

Step-by-step explanation:

Because the x-coordinate of the vertex is negative, only A or D could be the correct equation for this parabola.  D is correct because its constant (4) matches the y-coordinate of the vertex (-5, 4).

Answer:

if your looking for radius it would be 3.35 if your looking for surface area its 3.14(3.35)^2  

Step-by-step explanation:

Answer:

divide the figure into two parts.

area of triangle = 1/2×base×height

area of triangle = 1/2×3×3

area pf triangle = 4.5 units²

area of square = side²

area of square = 3²

area of square = 9unit²

Answer:

The figure is made up of a square and a triangle.

We will find both of their areas separately and then combining them will give us the required area.

Area of the triangle : ½ × base × height

= ½ × 3 × 3

= ½ × 9

= 4.5 units²

Area of the square : (side)²

= 3²

= 9 units²

Now, required area = (4.5 + 9) units²

= 13.5 units²

Answer:

x=5 y=-6

Step-by-step explanation:

3x+y=9 ------eqn1

y=4-2x -------eqn2

using substitution

put y=4-2x into eqn1

3x+4-2x=9

x=5

put x=5 into eqn2

y=4-2(5)

y=4-10

y=-6

Answer:

12.6cm

Step-by-step explanation:

12.6 cm²

Area formula: (A = πr²)

If the diameter is 4 cm.. then that would mean the radius is 2 cm because the radius is half of the diameter. So, we already know the radius.. we just have to find the circumference.

Circumference formula: (C = πd) or (C = 2πr)

Finding the circumference : 3.14 × 4 = 12.56 cm

So, we now have the radius and circumference.

Radius = 2 cm

Circumference = 12.56 cm

Finding the Area : 3.14 × 2 × 2 = 12.56 cm²

So, 12.56 rounded to the nearest tenth is 12.6 cm².

Hope this helped! :)

Answer:

[tex]n = \frac{1}{6} [/tex]

Step-by-step explanation:

Answer: i think its c

Step-by-step explanation:

Answer:

x + 2y = -2

Step-by-step explanation:

Well let's examine the relation between x and y in a perpendicular line.

We can use the fact that for a line Ax + By = C, any line with equation Bx + (-A)y = D is perpendicular (swapping A and B gives a mirror image with respect to the line x=y and changing one of the signs gives a mirror image with respect to axis x or y. Those two together give a perpendicular line).

So we're looking for a line with equation x + 2y = D

We know what it passes through the point (6, -4), so let's input it into the equation x + 2y = D

6 + 2*(-4) = D

6 - 8 = D

D = -2

So the equation is x + 2y = -2

note that 2x + 4y = -4

or any other multiple also works.

Answer:

the temperature was still suitable for the greenhouse

Step-by-step explanation:

Answer:

z=20

Step-by-step explanation:

(2z + 16) +124 =180

2z + 16 +124

2z +  140 = 180

2z     -140 -140

2z        =  40

z           =  20

Answer:

It is true

Step-by-step explanation:

the area of the rectangle is

72•66=4752

the area of the semi circle is

π33^2= 3421.19/2= 1710.595

4752-1710.595= 3041.405

rounded to nearest tenth

3041.4

Answer:

Step-by-step explanation:

I think it should be 20 because the line is similar to the 18 line so you can round up to 20.

Answer:

the correct answer is 7

Step-by-step explanation:

-5-(-7) = -5 +

two minus is plus so it is

-5 + 7

Answer:

D. The probability of selecting an orange is ³/₅.

Step-by-step explanation:

A is incorrect because there would be 4 apples combined (3 from bag one, 1 from bag two). That makes the chance of selecting an apple 2/5 (40%), not 3/10 (30%).

B & C are incorrect because 4/10 (40%) is less than 6/10 (60%)

That leaves D, which state that you have a 60% (3/5) chance selecting an orange, as our answer. That is correct as 3/5 = 6/10 = 60%.
