Can someone please help me thanks.

Answer:

48 centimetres wide

Step-by-step explanation:

you are at 3

you enlarge it and you get 6

second enlargement you get 12

third enlargement you get 24

fourth enlargement you get 48

if you times 3 by 4 you are not doubling the width each time you enlarge the photo

so it is easier to double it each time you enlarge it

The solution of equation for x is,

⇒ x = 4

We have to given that;

The equation is,

⇒√ (3x + 4) = 4

Now, We can simplify as;

⇒ √3x + 4 = 4

Take square both side,

⇒ 3x + 4 = 4²

⇒ 3x + 4 = 16

Subtract 4 both side,

⇒ 3x = 16 - 4

⇒ 3x = 12

Divide by 3;

⇒ x = 12/3

⇒ x = 4

Thus, The solution of equation for x is,

⇒ x = 4

Step-by-step explanation:

Answer:

61

Step-by-step explanation:

99 minus 38

Answer:

61 meters

Step-by-step explanation:

To find this answer, you need to subtract the length with trees from the total length of the course. With this information, you get an equation that looks something like x + 38 = 99, with x being the length of the course without trees.

Subtract 38 from both sides:

x + 38 = 99

  - 38   - 38

x = 99 - 38

Simplify:

x = 61

Answer:

350 girls.

5 unit represents 250 girls and the 7 unit represents 350 boys

Step-by-step explanation:

Add 5+7 =12

600÷12=50

RATIO OF BOYS TO GIRLS IS 7:5   SO

50x5=250 GIRLS.

7*50=350

so 5 unit represents 250 girls and the 7 unit represents 350 boys.

Answer:

65 degrees

Step-by-step explanation:

First, solve for the unknown angle( not the y's).

the angle 130 is supplementary to that angle so we will use an equation to solve it.  (supplementary means it adds up to 180 degrees)

x+130=180

 -130  -130

x      =   50           so, 50 is the measure of the interior angle

Now we have to use another equation to solve for y:

50+2y=180

-50      -50

2y      =  130

/2         /2

y     = 65

Thus, y is 65

So the right answer is 65 degree

The distance between the y-intercept of the function f(x)=3(2)ˣ and the y-intercept of the function g(x) for this case is given by: Option C: 8 units

The intersection of the graph of the function with the y-axis gives  y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

Suppose the given points are [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex], then the equation of the straight line joining both two points is given by

[tex](y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]

We're given that:

[tex]f(x) = 3(2)^x[/tex]

Its y-intercept is:

[tex]y = f(0) = 3(2)^0 = 3\times 1 = 3[/tex]

Assuming y = g(x) is a linear function, from the first two points [tex](x_1, y_1) = (-5,15)[/tex] and [tex](x_2, y_2) = (-2, 3)[/tex], we get:

[tex](y - 15) = \dfrac{3 - 15}{-2 - (-5)} (x -(-5))\\\\y -15 = -\dfrac{12}{3} (x+5)\\\\y-15 = -4x - 20\\y = -4x - 5[/tex]

Checking if really y = g(x) is linear or not by evaluating it on its rest of the points:

[tex]y = g(2) = -4(2) -5 =-8-5 = -13\\\\y = g(5) = -4(5) -5 = -25[/tex]

These outputs matches with the table output, so we can take:

[tex]g(x) = -4x -5[/tex]

Its y-intercept is:

[tex]y = g(0) = -4(0) -5 = -5[/tex]

The distance between 3 and -5 on the y-axis is the absolute difference between these values of y, evaluated as:

[tex]d = |3 - (-5)| = |8| = 8[/tex] units.

Thus, the distance between the y-intercept of the function f(x)=3(2)ˣ and the y-intercept of the function g(x) for this case is given by: Option C: 8 units.

Answer:

B

Step-by-step explanation:

Let's start by converting each of these into decimal form.

[tex]\pi\approx 3.1416\\\sqrt{10}\approx 3.1623\\\dfrac{22}{7}\approx 3.1428[/tex]

Therefore, the correct order is:

[tex]3.14, \pi, \dfrac{22}{7}, \sqrt{10}[/tex]

or answer choice B. Hope this helps!

Answer: B. 3.14, π, 22/7, square root of 10

Step-by-step explanation:

To order the numbers in increasing order, first solve for each to get the numbers into their simplest forms.

Pi can be estimated to 3.1415, which is already bigger than 3.14.

Knowing this, you can eliminate choice A, which lists pi as less than 3.14.

Dividing 22 by 7 gets you ~3.142, which is greater than both pi and 3.14.

Knowing this, you can eliminate choices C and D, which list 22/7 as less than 3.14 and pi.

The correct answer choice is B.

Step-by-step explanation:

y = |x+4| - 4 has a vertex of (-4, -4), and the vertex of the given graph is (3, 1). The shift between the first and second points given is 7 units to the left (6) and 5 units down (2)

The transformation that will change from f to g will be

Corner point of a function is the point where continuous function will not be differentiable.

here the function in the graph has the corner point at (3,1).

so now we have to transform the function f to function g where

g(x)= |x+4|-4

in the function g(x) the corner point will be the point where the value changes sudddenly.

so the corner point will be x+4=0

⇒x=-4

at x=-4, the value of the g(x)=|-4+4|-4=-4

so the corner point of function g will be (-4,-4).

Now the corner point of function f is (3,1).

Therefore to trnsform function f to g we have to first displace (3,1) to (-4,-4).

in x direction the displacement will be = -4-3 =-7 i.e.  horizontal shift left 7 units

in y direction the displacement will be =-4-1=-5 i.e. verical shift down 5 units

Therefore the transformation that will change from f to g will be
