Answer:
81
Step-by-step explanation:
put -36 over 1 and -4/9 in its reciprocal which is -9/4 and multiply.. -36(-9)=324
then multiply -1 by -4=4 now you have 324/4 which is simplified to 81..

this is the only thing i do not understand about geometry
Answer:
see explanation
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{opp}{20}[/tex] ( multiply both sides by 20 )
20 × tan40° = opp , thus
opp = 20 × 0.839 ≈ 16.78 , then
height of traffic light = 16,78 + 5 = 21.78 ft
------------------------------------------------------------------------
Using the tangent ratio in the right triangle
tan42.71° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{150}{d}[/tex] ( d is the distance between store and bank )
Multiply both sides by d
d × tan42.71° = 150 ( divide both sides by tan42.71° )
d = [tex]\frac{150}{tan42.71}[/tex] = [tex]\frac{150}{0.923}[/tex] = 162.5 m
Which of the following equations represent linear functions?
y=4(2x)−3
x2+y=1
y=2x√
y=−2
Answer:
y = 4(2x) − 3 y = −2Step-by-step explanation:
Given functions:
y = 4(2x) − 3 x² + y = 1 y = 2√ xy = −2Linear functions have the form of
ax + by + c = 0 or y = mx + bTherefore functions 1. and 4. are linear functions, the other two aren't
how do you Factor in algebra 2?
for example:
r^2-r-20
and
x^2+8x+12
(r-5)(r+4)
(x+6)(x+2)
Step-by-step explanation:
1 r^2 - 1 r - 20
multiply the first and third terms
-20 times 1 equals -20. take the -1
*what are two numbers that multiply together that equals -20 but add to equal -1?
-5 times 4 equals -20
-5 plus 4 equals -1
(r-5)(r+4)
1 x^2 + 8 x + 12
multiply the first and third terms
12 times 1 equals 12. take the 8
*what are two numbers that multiply together that equals 12 but add to equal 8?
6 times 2 equals 12
6 plus 2 equals 8
=(x+6)(x+2)
Which expression is NOT equivalent to a^3b^3
((a^2)b)((b^2)a)
(a^4)b^4−ab
((a^2b^2))/2ab
(ab)(ba)(ab)
Answer:
A. ((a^2)b)((b^2)a)
Step-by-step explanation:
A. ((a^2)b) ((b^2)a)
Open parenthesis
(a^2b)(b^2a)
a^3b^3
B. (a^4)b^4−ab
a^4b^4 - ab
C. ((a^2b^2))/2ab
(a^2b^2) / 2ab
D. (ab)(ba) (ab)
(a^2b^2)(ba)
Therefore,
a^3b^3 = ((a^2)b) ((b^2)a)
how do you evaluate cube roots and square roots( in simple words pls)
Answer:
To evaluate square roots, find the prime factorization. If all the exponents are even, then it is a square root! Just divide the exponents by 2, and multiply them together. To evaluate cube roots, find the prime factorization. If all the exponents are multiples of three, it is a cube root! Just divide the exponents by 3 and multiply them together.

Find the distance between the two points rounding to the nearest tenth (if necessary (8, 7) and (1, - 2)
Answer: 11.4
Step-by-step explanation:
You would use the distance formula.
(1−8)^2+(−2−7)^2
=(−7)^2+(−2−7)^2
=49+(−2−7)^2
=49+(−9)^2
=49+81
=130
= 11.4
I’m stuck lol if you know and can explain this pleas help tysm
Answer:
z=32
y=148
x=6
Step-by-step explanation:
z+73+75=180
Combine like terms
z+148=180
Subtract 148 on both sides
z=32
z and y are angles on a line
y+32=180
subtract 32 on both sides
y=148
x+148+26=180
combine like terms
x+174=180
subtract 174 on both sides
x=6
What are the missing parts that correctly complete the proof?
Given: point P is on the bisector of ABC.
Prove: point P is equidistant from the sides of ABC.
1. BP is the bisector of ABC- given
2. ABP≈CBP- ?
3. BXP and BYP are right angles- given
4. ?- all right angles are congruent
5. BP≈BP- ?
6. BXP≈BYP- ?
7. ?- corresponding parts of congruent triangles are congruent
8. Point P is equidistant from the sides of ABC- definition of equidistant
Answer:
Hello, I just took the test today. I will attach a screenshot. I hope I am not too late answering your question.
This question stumped me too at first. I hope this helps!
The missing parts that correctly complete the proof are;
2) Definition of a bisector
4) ∠BXP ≅ ∠BYP.
5) Reflexive property of congruence.
6) AAS congruence theorem.
7) Corresponding sides of congruent triangles are congruent.
We are given;
Point P is on the bisector of ∠ABC.
2) ∠ABP ≅ ∠CBP; The symbol ≅ means congruent. This means they are equal and it is true because it corresponds with the definition of a bisector means dividing into 2 equal parts.4) All right angles are congruent; Congruent means equal and the two right angles we have in the image are; ∠BXP and ∠BYP. Thus, we can write; ∠BXP ≅ ∠BYP.5) BP ≅ BP; This means that Line BP is congruent and equal to itself and this fulfils the theorem called reflexive property of congruence.6) ΔBXP ≅ ΔBYP; This means ΔBXP is congruent to ΔBYP. Since we have established that ∠BXP ≅ ∠BYP; ∠ABP ≅ ∠CBP; BP ≅ BP. It means we have 2 corresponding angles and one corresponding side equal to each other from the 2 congruent triangles and so we can say this fulfils the AAS congruence theorem.7) PX ≅ PY; This means PX is congruent to PY. From congruence theorem, corresponding sides of congruent triangles are congruent.

The sides of a triangle are as follows:
AB = 10 in
BC = 14 in
AC = 8 in
Order the angles of the triangle from smallest to biggest.
<B, <A, <C
<B, <C,<A
<A, <C, <B
<A, <B, C
Answer:
The order of the angles of Δ ABC from smallest to biggest is
∠B < ∠C < ∠A ⇒ B
Step-by-step explanation:
There is a fact about a triangle
The longest side is opposite to the greatest angleThe shortest side is opposite to the smallest angleLet us use this fact to solve our question
In Δ ABC
∵ AB = 10 inches
∵ BC = 14 inches
∵ AC = 8 inches
→ Find the longest and shortest sides
∴ BC is the longest side
∴ AC is the shortest side
∵ BC is opposite to ∠A
∴ ∠A is the biggest angle in measure
∵ AC is opposite to ∠B
∴ ∠B is the smallest angle in measure
∴ The order of the angles of Δ ABC from smallest to biggest is
∠B < ∠C < ∠A
What is the value of x in the figure below? In this diagram, ΔABD ~ ΔCAD.
Answer:
D
Step-by-step explanation:
The triangles CDA and ADB are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{CD}{AD}[/tex] = [tex]\frac{DA}{DB}[/tex] , substitute values
[tex]\frac{13}{x}[/tex] = [tex]\frac{x}{3}[/tex] ( cross- multiply )
x² = 39 ( take square root of both sides )
x = [tex]\sqrt{39}[/tex] → D

Write the following number in Scientific Notation.
Explain what you did to get your answer
560,000,000,000,000,000
Answer:
5.6 * 10^17.
Step-by-step explanation:
There are 17 digits after the 5 .
So it's 5.6 * 10^17.
Note that the first number must lie between 1 and 10.
I don't really understand which number we have to write in scientifc notation but I am assuming it is the number 560,000,000,000,000,000.
Ok so, 560,000,000,000,000,000 in scientific notation is 5.6 x 10^17.
This is because if you count the number of spaces behind the decimal point of 5.6 it is equal to 17. So, you would write the answer 5.6 x 10^17.
