The graph of y vx is translated 5 units to the left and 7
units up. What is the equation of the graph that results from
this translation?

Answers

y=-1.4x

Step-by-step explanation:

divide the change in y by the change in x to find the gradient,

7 divided by -5 [as the translation is to the left].

there might be a y intercept value, c as in

y=mx + c but with the given information without  thee starting points it is hard to find

The required equation of the graph that results from the translation is y = √(x + 5) + 7.

What is translation on the coordinate plane?

Translation on a coordinate plane is a transformation that moves an object or figure from its original position to a new position in a straight line. It is also called a "slide." In translation, all points of the object are moved by the same distance in the same direction.

Here,
To shift the graph of the function y = √x to the left by 5 units, we need to replace x with x + 5 in the equation. This will give us the graph of y = √(x + 5).

To shift the graph 7 units up, we need to add 7 to the entire function. This will give us the final equation of the translated graph:

y = √(x + 5) + 7.

Therefore, the equation of the graph that results from the translation is y = √(x + 5) + 7.

What is the perimeter of a square which has the same area as a circle with circumfrence of 4π

Answers

Answer:

Perimeter square = 8 sqrt(pi)

Step-by-step explanation:

The perimeter of a square is 4*s

The area of a circle is Area = pi * r^2

The circumference of a circle is C = 2*pi * r

C = 4 pi

4pi = 2*pi * r

r = 2

So the area of the circle is pi * r^2 = pi * 2^2 = 4pi

The square has the same area

Area = 4*pi

Square = 4*pi

s^2 = 4*pi

s = sqrt(4*pi)

s = 2*sqrt(pi)

The perimeter = 4 * 2 * sqrt(pi)

The perimeter = 8 * sqrt(pi)

The height of a triangle is 5cm more than half the base of the triangle. The area of the triangle is 6cm^2. Find the base and height of the triangle

Answers

Answer:

Base = 2 cm and height = 6 cm.

Step-by-step explanation:

Area = 1/2 * base + height

Let b be the base and h = height of the given triangle, then

6 = b/2 * h

6 = b/2(b/2 + 5)

b^2/4 + 5b/2 - 6 = 0

b^2 + 10b - 24 = 0

(b + 12)(b - 2) = 0

b = 2  (we neglect the negative b = -12)

So h = b/2 + 5 = 2/2 + 5 = 6.

the perimeter of a right angled triangle is 60 cm and its area is 120cm².find the lengths of the triangle.​

Answers

Step-by-step explanation:

The area of triangle given as 120 cm2

Area of Triangle = 1/2 x b x h = 120

therefore bxh = 240

240 can be factorized as 10 x 24

The perimeter of the triangle is given as 60

so the other side has to be 26 cm

As this is a right angle triangle it should satisfy pythagoras theorem

(10)2 + (24)2 = (26)2

100+576 =676

Hence the sides of the triangle are 10 cm, 24 cm and 26 cm

Solution:-

Total mean score = 40

[tex]mean \: = \frac{sum \: of \: observation}{number \: of \: observations} [/tex]

sum of observations

= mean × no of observations

= 40×100

Find th slope of the line passing through the points (5,8) and (6,12)

Answers

Answer:

Slope= 4

Step-by-step explanation:

y2-y1/x2-x1

5=x1 8=y1 etc.

12-8/6-5

=4/1

Answer:

The slope of the line is 4.

Step-by-step explanation:

To solve for the slope of the line, use the rise over run formula. The rise over run formula is a measure of how much something changes vertically compared to how much it changes in the horizontal direction. The rise over run formula calculates the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run). The formula looks like [tex]\frac{rise}{run}[/tex], but in terms of finding a slope, it looks like [tex]\frac{y_{2}-y_{1} }{x_2-x_1}[/tex].

For finding the slope of this line with the points (5,8) and (6,12), start by writing down the information given from the question.

[tex]y_2=12[/tex]

[tex]y_1=8[/tex]

[tex]x_2=6[/tex]

[tex]x_1=5[/tex]

Next, plug in the information given from the question into the formula, and the formula will look like [tex]\frac{12-8}{6-5}[/tex]. Then, simplify the equation, which will look like [tex]\frac{4}{1}=4[/tex]. The final answer will be 4.
