there is no picture its all black

Step-by-step explanation:

"The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short."

Round to the nearest hundredth 42.052

Vera_Pavlovna [14]

42.052

place value and digits:

4 = tens
2 = ones
0 = tenths
5 = hundredths
2 = thousandths

5 is in the hundredths place. To find if you round up or down, look at the digit to the right (thousandths in this case). It is a 2, which is less than 5, so you round down.

42.052 rounded to the nearest hundredth is 42.05

Draw the directed graphs representing each of the following relations:

GaryK [48]

Answer and Explanation:

Given : Different relations.

a) {(1,1), (1,2), (1,3)}

b) {(1,2), (2,1), (2,2), (3,3)}

c) {(1,1), (1,2), (1,3), (2,2), (2,3), (3,3)}

d) {(1,3), (3,1)}

To find : Draw the directed graphs representing each relations?

Solution :

A directed graph is defined as a set of vertices that are connected together where all the edges are directed from one vertex to another.

Now, We represent each relation through directed graph.

a) {(1,1), (1,2), (1,3)}

Here, 1 is connected to itself, 1 is connected to 2 and 1 is connected to 3.

Refer the attached figure (1).

b) {(1,2), (2,1), (2,2), (3,3)}

Here, 1 is connected to 2 and 2 is connected to 1,2 is connected to itself and 3 is connected to itself.

Refer the attached figure (2).

c) {(1,1), (1,2), (1,3), (2,2), (2,3), (3,3)}

Here, 1 is connected to itself, 1 is connected to 2,1 is connected to 3,2 is connected to itself , 2 is connected to 3 and 3 is connected to itself.

Refer the attached figure (3).

d) {(1,3), (3,1)}

Here, 1 is connected to 3 and 3 is connected to 1.

Refer the attached figure (4).

Wilson wants to know how long it will take his $1000 investment to double

riadik2000 [5.3K]

Answer:

Step-by-step explanation:

Take the log of both sides:

log(2) = t*log 1.015, so that:

log(2)

t = --------------- = 46.6 compounding periods, which is 46.6/4, or 11.6 years

log 1.015

Can't write this exponential equation as a logarithm; instead, CAN write it in logarithmic form.

Where would the point

serg [7]

Answer:

A) At x = 4 and y = 2

Step-by-step explanation:

When you have something like (4,2), as shown above, the first number in parenthesis is x while the second number is y.

So here, the 4 would be x and the y would be 2
