Exponential to Logarithmic: $\displaystyle b^m=x \rightarrow log_bx=m$

Step-by-step explanation:

Step 1: Define

Identify

0.77 = log(x)

Step 2: Solve for x

[Equality Property] Raise both sides to the 10th power: $\displaysytle 10^{0.77} = 10^{logx}$
Simplify: $\displaysytle x = 10^{0.77}$
Evaluate: $\displaysytle x = 5.88844$

For the triangles ABC and MNP m∠A = m∠M, AB = 16, AC = 10, MN = 7, MP = 24. Find the ratio of the A△MNP and A△ABC .

Digiron [165]

Answer:

Ratio of area of triangles MNP and ABC is 1.05

Step-by-step explanation:

There are 2 triangles ABC and MNP.

We are given that ,m∠A = m∠M.

AB = 16 and AC = 10.

MN = 7 and MP = 24.

Area of a triangle ∝ Product of any two sides.

So area of triangle ABC ∝ 16 $\times 10$

Area of triangle ABC = 160 $\times k$ ,

where k is a constant.

So area of triangle MNP ∝ 7 $\times 24$

Area of triangle MNP = 168 $\times k$

So ratio of area of triangles = $\frac{Area of MNP}{Area of ABC}$

= $\frac{168}{160}$

= 1.05

What would the coordinates of the new image be? (View Picture)

tino4ka555 [31]

Answer:

T(1, 5), R(7, 7), A(7, 1), M(4, 5)

Step-by-step explanation:

The mapping for -90° rotation is (x, y) ⇒ (y, -x).

for example, T(-5, 1) ⇒ T'(1, 5)

If you're doing this with pencil and paper, you can draw the image and axes the way it is, then rotate your drawing 90° clockwise (so the axes line up) and copy it into the first quadrant.
