Here are the figures you get with different values of eccentricity e.
e = 0: circle
0 < e < 1: ellipse
e = 1: parabola
e > 1: hyperbola

The conic section that has an eccentricity greater than 1 is ...
c. hyperbola

Slope intercept form that passes though the point (-2,-3) and has a slope of 5/2

olganol [36]

$\text{Given that,}\\\\(x_1,y_1) = (-2,-3), ~~\text{and slope,}~~m = \dfrac 52\\\\\\\text{Now,}\\\\y -y_1 =m(x-x_1)\\\\\implies y +3 = \dfrac52 (x+2)\\\\\implies y = \dfrac 52(x+2) -3\\\\\\\implies y = \dfrac{5}2 x + 5 -3 \\\\\\\implies y = \dfrac 52 x + 2\\\\\\\text{This is the slope-intercept form(y =mx+b)}.$

A square is shown below. Which expression can be used to find the area, in square units, of the shaded triangle in the square?

ELEN [110]

Answer:

Area = $\frac{1}{2} (6)(6)$

Step-by-step explanation:

Area of Triangle = $\frac{1}{2} (Base)(Height)$

Where Base = 6 , Height = 6

Area = $\frac{1}{2} (6)(6)$

Area = 3 * 6

Area = 18 units^2

Mr. Smith is 81 years older than his grandson, Victor. In 3 years, Mr. Smith will be four times as old as Victor. How old is Vic

puteri [66]

<h3>Answer :- </h3>

24 years

<h3>Solution :- </h3>

Let the age of victor be X .
and, the age of Mr.Smith be = 81 + x

♧ So, after 3 years = x+81 +3

81 + 3 + x = 4 ( x + 3 )
84 + x = 4x + 12

♧ now grouping the variables and constants together we get,

4x-x=84-12
3x = 72
x = 72/3
x = 24

♧ Thus, Victor's present age is 24 yrs.

Hope it helps ya ~

What are the blank numbers for 16, 17, 18, and 19

Natasha_Volkova [10]

Answer:

16: 0.5, 5, 7.5

17: 62, 434, 682

18: 12.3, 62.5, 10

19: 1, 75, 300

Step-by-step explanation:

16: 9/18=0.5 so halve the numbers

17: 186/3=62 so multiply numbers by 62

18: 24.6/2= 12.3 so multiply by 12.3 and divide for the last one

19: 125/5=25 so for the first one divide by 25 and for the last two times by 25

Write an exponential function in the form y=ab^xy=ab x that goes through points (0,8) and (2,288)

timofeeve [1]

Answer:

y = 8•6^x

Step-by-step explanation:

Here, we want to write an exponential equation

To fully write this, we need the values of a and b

From the first coordinates given;

8 = a•b^0

a = 8 since b^0 = 1

Furthermore;

288 = 8•b*2

b^2 = 36

b = √36

b = 6

So we have ;

y = 8•6^x
