Select all the correct graphs.
Choose the graphs that indicate equations with no solution.
Answers
The graphs with no solutions are the ones with no intercepts between the curves. These are the first one and the last one.
Which graphs indicate equations with no solutions?If we have an equation like:
f(x) = g(x).
One way of finding the solutions is to graph:
y = f(x) and y = g(x) and see where the two curves intercept.
From that, the graphs where the curves do not intercept are the graphs that indicate that the equations have no solutions.
The two graphs with no intercepts are the first one (top left) and the last one (bottom right), so these are the correct options.

For every 36 minutes of sprinting, Scarlett earned 12 dollars for charity. To find the unit rate of this, I would first need to structure the equation. In this case, I would use division, so my equation would be 36 ÷ 12 = 3. The final answer would be, for every 3 minutes, Scarlett earns $1. is this right? i will give 15 points:)
Answers
Answer:
$1 every 3 minutes
Step-by-step explanation:
Cause every 36 minutes Scarlett earns $12 and if you divide 36 by 12 it will give 3 minutes which means she earns $1 per 3 minutes. You're right.

Find the general solution of the given differential equation. Cos(x) dy dx (sin(x))y = 1
Answers
The general solution to the differential equation is y = sinx + c cosx.
What is differential equation?It is defined as the equation which contains functions, derivative of the functions to make an expression.
We have a differential equation:
[tex]\rm cosx\left(\dfrac{dy}{dx}\right)+\left(sinx\right)y\:=\:1[/tex]
Multiply by dx:
(cosx) dy + (sinx) y dx = dx
(cosx) dy = (1 - (sinx) y) dx
After simplification and integrating, we will get:
[tex]\rm y = \dfrac{tan x}{sec x}+ \dfrac{c}{secx}[/tex]
y = sinx + c cosx
Thus, the general solution to the differential equation is y = sinx + c cosx.

Answers
Answer:
x² - 14x - 15 = (x − 7)² − 64Then the coordinates of the vertex are (7 , -64)Step-by-step explanation:
x² - 14x - 15 = x² - 14x + (49 - 49) - 15
= (x² - 14x + 49) - 49 - 15
= (x² - 14x + 7²) - 49 - 15
= (x − 7)² − (49 + 15)
= (x − 7)² − 64
x² - 14x - 15 = (x − 7)² − 64
Then the coordinates of the vertex are (7 , -64)

Answers
Using a trigonometric realtion, we can see that x = 23.18cm
How to find the value of x?Here we have a right triangle, we can see that y = 6cm, and the angle theta is 15°.
Notice that y is the opposite cathetus to the known angle, and we want to find the value of x, which is the hypotenuse.
Then we can use the trigonometric relation:
sin(a) = (opposite cathetus)/hypotenuse.
Reaplacing what we know, we will get:
sin(15°) = 6cm/x
Solving that for x:
x = 6cm/sin(15°9
x = 23.18cm
