Answer:

  -27

Step-by-step explanation:

It looks like you're trying to evaluate ...

  \displaystyle 5^{\log_5{8}}-3^{\log_3{5}+\log_3{7}}=8-3^{\log_3{35}}=8-35=\boxed{-27}

__

The relevant rules are ...

  b^(log_b(x) = x

  log(a)+log(b) = log(ab)

Please, guys, help me out.
Maru [420]

Answer:

First we need to calculate ∠R

Since ∠R is one of three angles of ΔRDJ, we have:

∠R + ∠D + ∠J = 180°

∠R                   = 180° - ∠D - ∠J

∠R                   = 180° - 83° - 39° = 58°

Since ΔRDJ ~ ΔTRB, we can con conclude that:

∠R = ∠T

Because ∠R = 58°

=> ∠T = 58°

Step-by-step explanation:

Objective: Solving Piecewise Functions

Analyze the info in the graph.

We know that if x=1, the graph will coincide at 5.

If x is greater than 1, the answer will be x squared it answer so any positve interger greater than 1 the answer is that squared.

If x is less than 1, the answer will be double that x.

Let check the answer choices.

A is wrong because x is less than 1 so the answer should be 2(-2)=-4 not 4.

C is Wrong, since 5 is greater than 1, it must be 25 so 5^2=25

D and B are both right, 2 is greater than 1 so 2 squared =4 and Whenever x=1, it will equal 5.

PLS HELP<br> I BEG youuuu
Marina CMI [18]

Answer:

19 square units

Step-by-step explanation:

There are a LOT of different ways to solve this problem, most of which involve breaking up the shape into smaller shapes.  For me, it’s easier to draw a rectangle around the figure, find that area, and then subtract the four areas not in the figure.

Rectangle: would be from -3 to 3 (6) and -2 to 4 (6).  6x6=36

The four missing triangles:

AB = 1/2(3)(2)=3

BC = 1/2(2)(4)=4

CD = 1/2(2)(4)=4

DA = 1/2(4)(3)=6

6+4+4+3=17

36-17=19
