Answer:

Q3. 12 units
Q4. 6.33 units
Q5. 66.19°

Step-by-step explanation:

DE and DF are legs and EF is hypotenuse

DE = √EF² - DF²
DE = √13² - 5² = √169 - 25 = √ 144 = 12
DE = 12 units

PR is opposite side of angle Q and RQ is adjacent side

tan 54 = PR/RQ
tan 54 = PR / 4.6
PR = 4.6tan 54
PR = 6.33 units

As previous question, using tan as BC is opposite and AC is adjacent leg of angle A

tan A = 6.8/3
tan A = 2.266
A = arctan (2.266)
A = 66.19°

A marble is randomly selected from a bag. The probability of selecting a marble with dots on it is 0.2. The probability of selec

marin [14]

Answer:

0.5

Step-by-step explanation:

Let D be the event of selecting a marble with dots.

Let P be the event of selecting a purple marble.

The probability of selecting a marble with dots, P(D)=0.2

The probability of selecting a marble that is both purple and has dots, $P(D \cap P)=0.1$

We want to determine the probability of selecting a purple marble given that the marble has dots on it, P(P|D)

By the definition of conditional probability:

$P(P|D)= \dfrac{P(P \cap D)}{P(D)} \\= \dfrac{0.1}{0.2}\\ =0.5$

The probability of selecting a purple marble given that the marble has dots on it is 0.5.

What is the general term equation, an, for the arithmetic sequence 9, 5, 1, −3, . . . , and what is the 21st term of this sequen

marin [14]

Hello :
<span>the general term equation, an, for the arithmetic sequence is :
An = A1+d(n-1)
A1 : the first term and : d the common diference
in this exercice :
A1 = 9
d =(-3)-(1) =(1)-(5) =(5) -(9) = -4
An = 9-4(n-1)
An = -4n +13</span>

Question2 of 25If ASTU AABC, which congruences are true by CPCTC? Check all that apply.

Marysya12 [62]

If triangle STU ≅ triangle ABC, then ∠T ≅ ∠B, ∠S ≅ ∠A, and segment TU ≅ Segment BC are true by CPCTC. Option A, option B, and option D are correct.

Let's understand what is the congruence of the triangle.

If all three corresponding sides are equal and all three corresponding angles are identical in measure, two triangles are said to be congruent. These triangles can be moved, rotated, flipped, and turned to look exactly the same.

CPCTC stands for corresponding parts of congruent triangles are congruent.

Let's check in the triangle STU and triangle ABC;

triangle STU ≅ triangle ABC

So,

∠S ≅ ∠A

∠T ≅ ∠B

∠U ≅ ∠C

segment ST ≅ Segment AB

segment TU ≅ Segment BC

segment SU ≅ Segment AC

Thus, if triangle STU ≅ triangle ABC, then ∠T ≅ ∠B, ∠S ≅ ∠A, and segment TU ≅ Segment BC are true by CPCTC. Option A, option B, and option D are correct.

40 POINTS!!! WILL MAKE BRAINLIEST FOR FIRST ANSWER TO BE CORRECT!

vredina [299]

Answer:

Step-by-step explanation:

We want to basically find all the points at which the line y = 3 intersects the given graph of g(x).

y = 3 is simply a straight horizontal line intersecting the y-axis at (0, 3). If we draw this line, we will see that it intersects g(x) at 3 different points. This indicates that there are 3 values of x where g(x) = 3.

Hope this helps!
