Answer:

D

Step-by-step explanation:

the center is (0,8)

(to solve this just flip the signs on the constants being added to x and y (there is an invisible constant of 0 being added to the x))

the radius is 7 (or √49)

Answer:

b= 2x²; c = 4; 3 = 3 ; g = 6x

Step-by-step explanation:

\textbf{(1)}\\\sqrt{50{x}^{2} } = \sqrt{25\times2x^{2}} = 5\times \mathbf{\sqrt{2x^{2}}}\\\textbf{b = 2x}^{2}\\\\\textbf{(2)}\\\sqrt{32x} = \sqrt{16 \times 2x} = \mathbf{4}\times \sqrt{2x}\\\textbf{c = 4}\\\\\textbf{(3)}\\\sqrt{18n} = \sqrt{9 \times 2n} = \mathbf{3}\times \sqrt{2n}\\\textbf{e = 3}\\\\\textbf{(4)}\\\sqrt{72x^{2}} = \sqrt{36 \times 2x^{2}} = 6\times \sqrt{2} \times x\\= \mathbf{6x}\sqrt{2}\\\textbf{g = 6x}

Given a verbal description, how do you interpret key features of functions and graphs?
ArbitrLikvidat [17]

Answer:

A linear function can be written in the slope intercept form or a point slope form of a line. Where a table is given for values representing the function, the ordered pairs will represent points on the line.The gradient of the line is a ratio of rise to run from the table values.In slope intercept form, the gradient and initial value of the function are indicated.

For example in a function f(x)=mx+b , m is the gradient of the line and b is the y-intercept value of the function.

To find the slope, m, you divide the difference between y-values by the difference in corresponding x-values of any two points on the line.

A decreasing linear function has a negative slope; if m<0 then f(x)=mx+c is decreasing

An increasing linear function has a positive slope where m>0.

What is the perimeter of the fifth square in this pattern?
torisob [31]
The first square has side lengths of 4 units(because the square root of 16 is 4). The second square has side lengths of 8 units. The third square has side lengths of 12 units. As you can tell, the side lengths increase by 4. So the fourth square will have side lengths of 16 units, and the fifth square will have side lengths of 20 units. The question wants the perimeter, so the answer is 20*4(sum of 4 sides of equal lengths) which is 80 units.

1. A penny is dropped from the top of the empire state building. The function h(t) = -16t^2 +1250 describes the height of the pe
liubo4ka [24]

Answer: 8.83\ s

Step-by-step explanation:

Given

Height of the dropped penny is given by

h(t)=-16t^2+1250

When penny hit the ground, h(t)=0

\therefore -16t^2+1250=0\\\Rightarrow 16t^2=1250\\\\\Rightarrow t^2=\dfrac{1250}{16}\\\\\Rightarrow t=\sqrt{\dfrac{1250}{16}}\\\\\Rightarrow t=8.83\ s

Thus, it takes 8.83 s to hit the ground.
