y=x^2\\\\for\ x=\pm2\to y=(\pm2)^2=4\to(-2;\ 4);\ (2;\ 4)\\\\for\ x=\pm1\to y=(\pm1)^2=1\to (-1;\ 1);\ (1;\ 1)\\\\for\ x=0\to y=0^2=0\to (0;\ 0)

Shift the graph of the function y = x², 5 units down /look at the picture #1/.

y > x^2-5 /look at the picture #2/ - your answer

Answer:

Graph 2

Step-by-step explanation:

Here, the given inequality is,

y>x^2-5-----(1)

At (0,0),

0>0-5

\implies 0 > -5       ( True )

So, The shaded region must contain the origin,

Hence, Graph 1 and Graph 3 can not be the graph of y>x^2-5,

Now, we know that, The standard form of a parabola is,

y=a(x-h)^2+k

Where, (h,k) is the vertex of the parabola,

From equation (1), the related equation of inequality (1) can be written,

y=(x-0)^2+(-5)

By Comparing,

The vertex of the related parabola of inequality (1) is (0,-5),

⇒ The vertex of the given parabola must be lie on the negative y-axis

Thus, Graph 3 can not be the graph of the given equation,

Therefore, Graph 2 must be the graph of the given inequality.

Answer:

y = 4x - 5

Step-by-step explanation:

y = mx + b

By putting above values in equation (i)

-1 = 4 (1) + b

-1 = 4 + b

-5 = b

b = -5

y = 4x - 5

Luda [366]
The complete question is
<span>Bradley made a house for his dog, Bowser, out of wood with a cube base and a triangular prism top. The dimensions of the dog house are a = 2 feet, b = 1 foot, and c = 1.4 feet.
</span><span>If Bradley plans to paint the outside of the dog house blue, not including the bottom, how many square feet of paint will he use?

the picture in the attached figure
</span>
we know that

surface area of the figure=surface area of cube+surface area of triangular prism

surface area of cube=4*a²----> 4*2²-----> 16  ft²

surface area of triangular prism=2*[a*c]+2*[a*b/2]---> 2*[2*1.4]+[2*1]
surface area of triangular prism=5.6+2----> 7.6 ft²

surface area of the figure=16 ft²+7.6 ft²----> 23.6 ft²

the answer is
23.6 ft²

Almost done. I need help with this part

Answer:

\%Percent = 14.3\%

Step-by-step explanation:

Required

15 is what percentage of 105

To do this, simply divide 15 by 105 multiplied by 100%.

So, we have:

\%Percent = \frac{15}{105} * 100\%

\%Percent = \frac{15*100}{105}\%

\%Percent = \frac{1500}{105}\%

\%Percent = 14.3\% --- approximated
