Hello from MrBillDoesMath!

Answer: g(x) = (x+3) ^2 + 3

Discussion:

First, the graph looks like the parabola y = x^2 BUT its smallest y-value is +3. That suggests the equation g(x) = x^2 + 3 BUT the parabola is shifted 3 units to the left. This suggest we take our last guess (x^2 +3) and shift it 3 units to the left, giving g(x) = (x+3)^2 + 3

Note that g(-3) = (-3 +3)^2 + 3 = 3

Plot the image of point P under a translation by 4 units to the left and 3 units down.

We are given the following point:

$P=(-2,-4)$

The given transformation is the following:

$(x^{\prime},y^{\prime})=(x-4,y-3)$

Replacing the values:

$\begin{gathered} P^{\prime}=(-2-4,-4-3) \\ P^{\prime}=(-6,-7) \end{gathered}$

Therefore, the image is (-6,-7)

Fred’s company is planning a new logo. The diagrams show two similar versions of the planned logo.

Answer:

a=7.2*1.5=10.8 cm

b=6.3/1.5=4.2 cm

$\pounds 4.48*2.25=\pounds 10.08$

Step-by-step explanation:

<u>Proportional Geometric Shapes </u>

A) We are given two similar shapes of a logo. They are to be proportional. We only need to find the proportion ratio of two of them to find the rest of the lengths.

The upper sides have 7.5 cm and 5 cm respectively. This gives us the ratio

$\displaystyle r=\frac{7.5}{5}=1.5$

Which means all the measures of the smaller logo are 1.5 smaller than those of the larger. This means

b=6.3/1.5=4.2 cm

a=7.2*1.5=10.8 cm

B) To paint the logos, we need to cover its surface, so the ratio of the surface is 1.5*1.5=2.25

This means the cost to paint the larger logo is

$\pounds 4.48*2.25=\pounds 10.08$

Probability of rolling a 10, 11 or 12 on a 12 sided die

mario62 [17]

There is a 1 in four chance of rolling those 3 numbers. You know this because there is a 3/12 chance of of rolling a 10,11, or 12. Simplify the fraction and you get 1/4.

Identify the slope and y-intercept of the graph of the equation Y=3/4x-2

sukhopar [10]

Hey there! :)

y = 3/4x - 2

To find the slope and y-intercept, simply use slope-intercept form to understand this.

Slope-intercept form is : y = mx + b ; where m = slope, b = y-intercept.

Therefore, you must ask yourself : which value is in the "m" spot and which value is in the "b" spot in our given equation?

Using this logic, we can come to the conclusion that :

Slope = 3/4 & Y-intercept = -2

~Hope I helped! :)
