Answer:

Part A : It is horizontal shift to left by 3 units and vertical shift upward 4 units That is your rule for the 1st one

Problem Statement

The question asks us to write out the rule for the translation given in Question 1 and 2.

Part B: The translation for the second image is x shifts right by 1 unit and y shifts upwards by 8 units

Step-by-step explanation:

To solve the question, we need to simply consider just one vertex of the figures given. The figures doesn't change shape or size, that is why we can consider just one vertex.

Considering vertex D with coordinate (-5, -3) and its image D' with coordinate (4, 5).

To know the rule, we simply look at the transformation formula

$(x,y)----> + (x~+m,~y+n) --->~(x',y')$

where, M and N are the translation magnitude

$x'~and~ y' Are~ the~new~Coordinates$

Translation is a term used in geometry to describe a function that moves an object a certain distance. The object is not altered in any other way. It is not rotated, reflected or re-sized.

Answer:

x = 12.6 pennies

Step-by-step explanation:

total number of coins = 1 + 2+ 4 + 3 = 10 coins

P(penny) = $\dfrac{1}{10}$

P(nickels) = $\dfrac{2}{10}$

P(dimes) = $\dfrac{4}{10}$

P(quarters) = $\dfrac{3}{10}$

hence average value of the coin

x = Penny x P(Penny) + nickel x P(nickel) + dimes x P(dimes) + quarters x P(quarters)

nickels = 5 pennies dimes = 10 ; and quarters = 25 pennies

$x = 1 \times \dfrac{1}{10} + 5\times \dfrac{2}{10} +10\times \dfrac{4}{10} + 25\times \dfrac{3}{10}$

x = 0.1 + 1 + 4 + 7.5

x = 12.6 pennies

hence, the average pennies for the first draw is equal to x = 12.6 pennies

Could someone help me rnnn?

Answer:

vertex = (0, -4)

equation of the parabola: $y=3x^2-4$

Step-by-step explanation:

Given:

y-intercept of parabola: -4
parabola passes through points: (-2, 8) and (1, -1)

Vertex form of a parabola: $y=a(x-h)^2+k$

(where (h, k) is the vertex and $a$ is some constant)

Substitute point (0, -4) into the equation:

$\begin{aligned}\textsf{At}\:(0,-4) \implies a(0-h)^2+k &=-4\\ah^2+k &=-4\end{aligned}$

Substitute point (-2, 8) and $ah^2+k=-4$ into the equation:

$\begin{aligned}\textsf{At}\:(-2,8) \implies a(-2-h)^2+k &=8\\a(4+4h+h^2)+k &=8\\4a+4ah+ah^2+k &=8\\\implies 4a+4ah-4&=8\\4a(1+h)&=12\\a(1+h)&=3\end{aligned}$
