The Above expression can we showed as :

here, the squared number is x

Hope this helps, if not sorry.

Answer:

You will use the formula y2-y1 over x2-x1.

This would make 7-5 over 1+3.

7-5=2 and 3+1=4. 2/4=1/2.

The answer is 1/2 :) If it turns out wrong, then the answer is most definitely 2.

y=3/4+9/-4

Answer:

312.5 cm²

Step-by-step explanation:

Since the figures are similar , then

ratio of heights = a : b

ratio of areas = a² : b²

Here linear ratio = 12 : 15 = 4 : 5 , then

ratio of areas = 4² : 5² = 16 : 25

let x be the area of B , the using proportion

[tex]\frac{200}{16}[/tex] = [tex]\frac{x}{25}[/tex] ( cross- multiply )

16x = 5000 ( divide both sides by 16 )

x = 312.5

Area of shape B is 312.5 cm²

Answer: 11.31

Step-by-step explanation:

Using the equation of an parabola, it is found that the value of p is 0.5.

The equation of a parabola that is concave to the left or to the right, that is, that has directrix y = k, and vertex (h,k), is given by:

[tex](y - k)^2 = 4p(x - h)[/tex]

The focus is at: (h, k + p).

The directrix is at: y = k - p

For this problem, we have that:

Since [tex]k = 3 - p[/tex]:

[tex]3 - p - p = 4[/tex]

[tex]2p = 1[/tex]

[tex]p = \frac{1}{2}[/tex]

[tex]p = 0.5[/tex]

The value of p is 0.5.

Answer:

220km

Step-by-step explanation:

Time taken (t) = 2hrs 45 min

= 2.75 hrs

AV =80km/hrs

Displacement or Distance (d) =?

We have,

AV = d÷t

80 = d÷2.75

80 × 2.75 = d

d = 220km

Answer:

13.896 kg

Step-by-step explanation:

Volume of Gold Bar = Area of [Trapezium x Length of Bar]

Length of Bar = 16 cm

Area of Trapezium = 2 × Area of Triangle + Area of Rectangle

Area of Triangle = 0.5 × 5 × 3 = 7.5 cm²

2 × Area of Triangle = 2 × 7.5 = 15 cm²

Area of Rectangle = 6 × 5 = 30 cm²

Area of  Trapezium = 15 + 30 = 45 cm²

Volume of Gold Bar = 45 × 16 = 720 cm³

Density of Gold = 19.3 g/cm³

Mass of Gold Bar = 720 × 19.3 = 13896 g = 13.896 kg

Mass of Gold Bar = 13.896 kg

Therefore the mass of the Gold Bar is: 13.896 kg (kilograms).

Answer:

13.896kg

Step-by-step explanation:

First, find the volume of the trapezium.

Volume = area of cross-sectional area times the length (16cm)

[(a+b)/2] times height

(6+12)/2 x 5

(18/2) x 5

9 x 5

= 45 <-- area of cross section

45 x 16 = 720 cm^3 <-- volume

To find the mass, multiply volume times density

720 x 19.3 = 13 896g  = 13.896kg

Answer:

Sarah is correct: lines l and m are not parallel.

Step-by-step explanation:

Given that m < 1 = 130°, and m < 7 = 45°,

Sarah is correct, that lines l and m are not parallel.

If lines l and m were parallel cut by the transversal, n, then its exterior angles < 1 and < 7 that lie on the same side of the transversal should be supplementary.  In other words, m < 1 and m < 7 should have a sum of 180°

Since according to the given prompt that m < 1 = 130°, and m < 7 = 45°, the sum of their measure add up to 175°, and not 180°.

Therefore, lines l and m are not parallel.

      The question gives us two points,  (-3,-3) and (-9,5), from which we can find the slope and later the equation of the line.

Finding the Slope  

The slope of the line (m)   = (y₂ - y₁) ÷ (x₂ - x₁)

                                           = (5 -(-3)) ÷ (-9 -(-3))      

                                           =  (5 + 3) ÷ (-9 + 3)    

                                           =   - ⁴/₃  

Checking my answer visually:  

Finding the Equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line. Once we have that equation, we can graph it to see if it passes through the two points. If it does, then we calculated the slope correctly.

                                ⇒  y - (-3) = - ⁴/₃ (x - (-3)        [ using the point (-3, -3)]

                                       y + 3  = - ⁴/₃ (x + 3)

Step-by-step explanation:

-0.2(25x+5)-5 = 4

We move all terms to the left:

-0.2(25x+5)-5-(4) = 0

We add all the numbers together, and all the variables

-0.2(25x+5)-9 = 0

We multiply parentheses

-5x-1-9 = 0

We add all the numbers together, and all the variables

-5x-10 = 0

We move all terms containing x to the left, all other terms to the right

-5x= 10

x=  10/-5

x= -2

Answer:

x=-2

Step-by-step explanation:

step 1 -5x-1-5=4

step 2 -5x-6=4

step 3 -5x=10 cause you add 6 on both sides

step 4 and then divide both sides by -5 to get x=-2

Answer:

8d : 8r = Ratio =  1 : 4

Step-by-step explanation:

Area of 8cm diameter = 4cm radius = formula pi x 4^2

= 50.2654825

= 50.27 m^2     rounded to 2dp as meters

Area of 8cm radius = formula pi x 8^2

=201.06193

= 201.06,^2     rounded to 2dp as meters

201.06193 / 50.2654825 = 4

4 x 50.265 = 201.061

    =        1    :   4

8d : 8r = Ratio =  1 : 4

The ratio of  the area of circle with an 8m diameter to a circle with an 8m radius is 1:4.

A term that is used to compare two or more numbers and to indicate how big or small a quantity is when compared to another is called ratio.

Area of a circle is the region covered or enclosed within its boundary.

The formula for the area of circle is give by

[tex]Area = \pi r^{2}[/tex]

Where,

r is the radius of the circle

According to the given question.

We have two circle.

One with the diameter 8m.

⇒ Radius, [tex]r_{1} = \frac{8}{2} =4m[/tex]

Therefore,

the area of circle with 4m radius

= [tex](4)^{2} \pi[/tex]

[tex]=16\pi[/tex]

Also, another circle with the radius 8m.

Therefore,

The area of the circle with the radius 8m

[tex]\pi (8)^{2} \\= 64\pi[/tex]

So,

the ratio of the area of circle with  an 8m diameter to a circle with an 8m radius = [tex]\frac{16\pi }{64\pi } =\frac{1}{4}[/tex]

Hence, the ratio of  the area of circle with an 8m diameter to a circle with an 8m radius is 1:4.

Answer:

- The graph is decreasing over its entire domain

- The graph is symmetrical about the origin

Step-by-step explanation:

The graph has an unremovable discontinuity at X=0, therefore all continuity answers are incorrect.

The graph is neither symmetrical about the x-axis nor y-axis, but if it were to be rotated around the origin, it would be symmetric.

On both sides of the graph, the slope is decreasing.

Therefore:

- The graph is decreasing over its entire domain

- The graph is symmetrical about the origin
