JL is a common tangent to circles M and K at point J. If angle MLK measures 61ᵒ, what is the length of radius MJ? Round to the n

Dvinal [7]

In the problem of insufficient data quantities. I can get a general solution.We know that tangent to a circle is perpendicular to the radius at the point of tangency. It's mean that triangles LJM and LJK are rights.

Let angle JLK like X.

So, angle JLM=61-x.

And it's mean that by using right triangle trigonometry

Radius MJ = LM*cos(61-X)

What are the values of the coefficients and constant term of 0 = 4 – 7x2 + x in standard form?

katen-ka-za [31]

ANSWER

$a = - 7$

$b = 1$

$c = 4$

EXPLANATION

The given quadratic equation is:

$0 = 4 - 7 {x}^{2} + x$

We rewrite in the standard quadratic equation form to obtain,

$- 7 {x}^{2} + x + 4 = 0$

Comparing this to the general standard quadratic equation.

$a {x}^{2} + bx + c = 0$

We have my

$a = - 7$

$b = 1$

$c = 4$

Brynn and Denise launch their rockets at the same time. The height of Brynn’s rocket, in meters, is given by the function f(x)=-

Vladimir [108]

Answer:

The height of rocket is 102.7 meter.

Step-by-step explanation:

Given : Brynn and Denise launch their rockets at the same time.

The height of Brynn’s rocket, in meters, is given by the function $f(x)=-4.9x^2+75x$ , where x is the number of seconds after the launch.

The height of Denise’s rocket, in meters, is given by the function

$g(x)=-4.9x^2+50x+38$ , where x is the number of seconds after the launch.

There is a moment when the rockets are at the same height.

To find : The height

Solution :

When the rockets have same height

So, $f(x)=g(x)$

$-4.9x^2+75x=-4.9x^2+50x+38$

$-4.9x^2+75x+4.9x^2-50x=38$

$25x=38$

$x=\frac{38}{25}$

$x=1.52$

Now, we put x value in any of the function to find height.

$f(x)=-4.9x^2+75x$ , x=1.52

$f(x)=-4.9(1.52)^2+75(1.52)$

$f(x)=-11.32096+114$

$f(x)=102.67$

Nearest tenth = 102.7

Therefore, The height of rocket is 102.7 meter.
