Answer:

$7.22 or $7.217

Step-by-step explanation:

$7.22 would be the answer because 70% of 10.31 is what you are looking for which is 7.217 which is rounded to 7.22

Answer:

1st Option

Step-by-step explanation:

When we draw out our triangle, we see that the height leg is 17 m and the horizontal leg is 100 m with our unknown angle of elevation <em>x</em>:

tanx° = 17/100

$x = tan^{-1}(\frac{17}{100})$

Write down an (in)equality which describes the solid ball of radius 3 centered at (7,1,−1). It should have a form like x2+y2+(z−

masya89 [10]

Answer:

$(x-7)^2+(y-1)^2+(z+1)^2-9\le 0$

Step-by-step explanation:

A ball is the solid inside a surface which is a sphere.

The equation of a sphere has the form:

$(x-h)^2+(y-k)^2+(z-s)^2= r^2$

Where (h,k,s) is the center and r is the radius.

When we plug the given center (7,1,-1) and radius 3 we get:

$(x-7)^2+(y-1)^2+(z+1)^2= 3^2$

Then we turn this into an inequality: Since the ball is inside the surface we must use the $\le$ symbol.

$(x-7)^2+(y-1)^2+(z+1)^2\le 9$

Then we just subtract 9 from both sides to get:

$(x-7)^2+(y-1)^2+(z+1)^2-9\le 0$

A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis is $f(x) = -8(3^x)$ .

<u>Step-by-step explanation:</u>

Here we have to make A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis . Let's find out:

We have ,

A function that represents the exponential function f(x)= 3 to the power of x

Following is the equation for above statement :

⇒ $f(x) = 3^x$

A vertical stretch by a factor of 8

Following is the equation for above statement :

⇒ $f(x) = 8(3^x)$

A reflection across the x-axis

Following is the equation for above statement :

⇒ $f(x) = 8(3^x)(-1)$

⇒ $f(x) = -8(3^x)$

Therefore , A function that represents the exponential function f(x)= 3 to the power of x after a vertical stretch by a factor of 8 and a reflection across the x-axis is $f(x) = -8(3^x)$ .
