y = −one twentieth(x − 3)2
y = −one twentieth(x + 3)2
y = one twentieth(x − 3)2
y = one twentieth(x + 3)2

Answers

Answer 1

Answer:

y = -1/20(x + 3)²

Step-by-step explanation:

Consider the parent function:

y = x²

The graph of the function open up and the vertex is at the origin, the point (0, 0)

Now, if it opens down, it means it is a reflection of the parent function over x axis, hence it has a negative coefficient, the function becomes:

y = -x²

The vertex is shifted to the point (-3, 0). It means the function also translated left by 3 units, the function becomes:

y = -(x + 3)²

Since all the options have 1/20 as a coefficient, our function is:

y = -1/20(x + 3)²

This is option B

Angle JML = Angle JKL ....( each 90°)

MJ = JK ....( Both measures 7)

Hence, by SAS criteria, ∆ MJL = ∆ LJk

Also,

∠MJK = ∠MJL+∠LJK

∠MJK = 32°+32°

Required

Player with the most runs

The number of runs is represented by the y coordinates.

So, the player with the most runs has the highest y coordinate.

From the attached plot, the y coordinate of each player is:

[tex]Paulo = 5[/tex]

[tex]Rebecca = 4[/tex]

[tex]Nardine = 9[/tex]

[tex]Jason = 10[/tex]

Guengle works in urban landscape design a truck arrived pouring a cone shaped pile of gravel six feet high with a diameter at the base of 8.2 ft how much gravel was delivered use pie\

Answers

Answer:

[tex]105.56\ ft^3[/tex] of gravel was used.

Step-by-step explanation:

Given that,

The height of a cone, h = 6 feet

The diameter of the base of cone, d = 8.2 feet

Radius, r = 4.1 feet

We need to find the amount of gravel was delivered. The volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times 4.1^2\times 6\\\\V=105.56\ ft^3[/tex]

So, [tex]105.56\ ft^3[/tex] of gravel was used.

30. Work out the next two terms, giving your answers as fractions decimals or percentages. The sequence below is linear. 0.6 75% 9 10 \ (2 marks)

Answers

Answer:

The next two terms are: 1.05 and 1.20

Step-by-step explanation:

Given

[tex]Sequence: 0.6, 75\%, 9/10[/tex]

Required

Write out the next two terms

Since it is a linear sequence; first, we calculate the common difference (d)

[tex]d = 75\% - 0.6[/tex] or [tex]d = 9/10 - 75\%[/tex]

Express as decimals

[tex]d = 0.75 - 0.6[/tex] or [tex]d = 0.9 - 0.75[/tex]

[tex]d = 0.15[/tex] (in both cases)

So, we add 0.15 to 9/10, to get the next term

[tex]Next = 9/10 + 0.15[/tex]

[tex]Next = 0.9 + 0.15[/tex]

[tex]Next = 1.05[/tex]

Add 0.15 to 1.05, to get the next term

[tex]Next = 1.05 + 0.15[/tex]

[tex]Next = 1.20[/tex]

The next two terms are: 1.05 and 1.20

Answers

Answer:

y=3x-6.5

Step-by-step explanation:

y-y1=m(x-x1)

y-(-0.5)=3(x-2)

y+0.5=3x-6

y=3x-6-0.5

y=3x-6.5

The slope of a line indicates the measure of the steepness and the direction of the line. The slope of any line can be calculated using any two distinct points lying on the line. The equation is y = 3x-6.5. The correct option is D.

What is equation of a line?

The equation of a line is an algebraic form which represents the set of points, which together form a line in a coordinate system. The equation of line is a linear equation with a degree of one. It can be formed with the help of the slope and a point on the line.

The equation of a line passing through the point and slope is given as:

(y - y₁) = m (x - x₁)

(y - -( 0.5)) = 3 ( x - 2)

(y + 0.5) = 3 (x - 2)

(y + 1/2) = 3 (x - 2)

or

y + 0.5 = 3x - 6

y = 3x - 6.5

Thus the correct option is D.
