Is knowing the coordinates of the vertex of a parabola enough to determine the domain and range?a.No: we would have no information about the domain. b.Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≤ n. c.No: we would need to know if the vertex is a minimum or a maximum. d.Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≥ n.

This is one of the fundamental transformation functions. Figure 2 points drew the taskThe x-axis is the axis of symmetry. We draw several pairs of points satisfying the conditions jobs.

see Figure 1. Different points . The x coordinate of points does not change. While the value of the y-coordinate is the number opposed . The points must be at the same distance from the axis x and at the same distance from the axis y . The x-axis is the axis of symmetry

A deer population is estimated to be 4,350. The growth rate of the population is given by the equation y=4350(1.07) . What is the percent rate of growth of the deer population?43.5%

107%

7%

0.07%

Algebra 2

Answers

Answer:

Step-by-step explanation:

Analyzing the growth rate of 1.07:

If the growth rate is a number greater than 1, we have exponential growth; if the growth rate is a number greater than 0 but less than 1, we have exponential decay.

Our growth rate is actually growth.  But the rate of growth is not 107%.  The rate of growth means that we already had 100% of the population and that it is growing by 7% each year.  100% + 7% = 107%; as a decimal, 1.07

So the rate of growth is 7%

Whats The common denominator fractions for 1/2 and 1/4

Answers

4, you can change 1/2 to 2/4
4 because 2 can be 4 and 4 is just 4 itself

-3x+4=16
PLEASE SOLVE THIS!!

Answers


-3X+4=16

Subtract 4 from each side.

-3x+4-4=16-4

-3x=12

Divide each side by -3.

x=-4

I hope this helps!
-3x+4=16
Subtract 4 from 16 
-3x=12
x= -4 because 3 times 4 =12 yet in order to make a negative number into a positive number, put two negative numbers together, and it's positive.

Divide and express the result in standard form. 8/7-i

Answers

i=√(-1)\to i^2=-1\ (i-the\ imaginary\ unit)\n----------------------\n\n(8)/(7-i)\n\nuse\ (a-b)(a+b)=a^2-b^2\n\n(8)/(7-i)\cdot(7+i)/(7+i)=(56+8i)/(7^2-i^2)=(56+8i)/(49-(-1))=(56+8i)/(49+1)=(56+8i)/(50)=(56)/(50)+(8)/(50)i\n\n=\boxed{(28)/(25)+(4)/(25)i}
assuming the problem is 8/(7-i) you would multiply the fraction by (7+i)/(7+i)
This would then simplify to 8(7+i)/50 which can be simplified down to 4(7+i)/25
