Answer:

Step-by-step explanation:

y = a(x - p)^2 + q....the graph of the parabola represented by this quadratic function has an axis of symmetry represented by the equation x = p.

f(x) = (x + 3)^2 - 4.....the axis of symmetry is in the p position of the formula used above.....so the axis of symmetry is -3, therefore, ur equation is x = -3

but before u do anything, u have to make sure ur quadratic equation is in vertex form...in the form of y = a(x - p)^2 + q

gogolik [260]

Answer:

Surface area: 250

Volume: 1375

Step-by-step explanation:

Scale factor: 4:5

This means that the dimensions of the larger figure are 5/4 of those in the smaller figure.

Surface area:

The surface area is found multiplying the square of the change(5/4) by the original surface area(160). So

$S = (\frac{5}{4})^2 \times 160 = \frac{25}{16} \times 160 = 25 \times 10 = 250$

Volume:

The volume is found multiplying the cube of the change(5/4) by the original volume(704). So

$S = (\frac{5}{4})^3 \times 704 = \frac{125}{64} \times 704 = 125 \times 11 = 1375$

Answer:

$1.61*10^{8} \\and\\3.3*10^{-7}$

Step-by-step explanation:

We can use properties of exponents to solve these equations. Remember that when multiplying exponents, we 'add' them.

--------------------------------------

$(2.3*10^{1})(7*10^{6})= \\16.1*10^{7}=\\1.61 *10^{8}$

For the next question:

$(1.1*10^{-5})(3*10^{-2})=\\ 3.3*10^{-7}$

These are your answers!
