58 +58 = 116
180-116 = 64
So angle 4 = 64
Let u = <3, 3> and v = <11, 8>. Find u + V.
The sum of the given vectors is 14i+11j.
Given that are vectors u = <3, 3> and v = <11, 8> we need to find u + v,
So,
Considering the vectors, a and b in two-dimensional,
\(\overrightarrow{a} = x_1i+y_1j\\\overrightarrow{b} = x_2i+y_2j\\\)
The following step is used to find out the vector sum of a and b;
i-component of the vector a is added with the i-component of the vector b,
j-component of the vector a is added with the j-component of the vector b,
Therefore, the sum is =
\(\overrightarrow{a}+\overrightarrow{b} = (x_1+x_2)i +(y_1+y_2)j\)
Here,
\(\overrightarrow{u} = 3i+3j\\\\\overrightarrow{v} = 11i+8j\)
The sum =
\(\overrightarrow{u}+ \overrightarrow{v} =(3i+3j)+(11i+8j)\\\\= (3+11)i + (3+8)j\\\\= 14i+11j\)
Hence the sum of the given vectors is 14i+11j.

Compare your answer with the average density of the giant's envelope, if it has a 0.5 solar mass and its radius is 0.6 AU . Express your answer using two significant figures.
The required average density of the giant envelope is equal to 3.30 x 10^9 kg/m^3.
Average density of the giant's envelope, required the mass and volume of the envelope.
Let us assume that the giant is a sphere with a radius of 0.6 AU,
the volume of the envelope is ,
V = (4/3)πr³
= (4/3)π(0.6 AU)³
= (4/3)(3.14)(0.6 × 149.6 ×10⁶ )³
To convert this volume to units of cubic meters,
Multiply by the conversion factor by,
1 AU = 149.6 x 10⁶m
⇒1 AU³ = (149.6 x 10⁶ km)³
⇒1 AU³ = 3.35 x 10³³ m³
Now ,calculate the density of the giant's envelope using the formula,
density = mass / volume
Giant's envelope has a mass of 0.5 solar masses,
which is equivalent to,
M = 0.5 x 1.99 x 10³⁰ kg
= 9.95 x 10²⁹ kg
Average density of the giant's envelope is equals to,
⇒ density = 9.95 x 10²⁹ kg / (4/3)(3.14)(0.6 × 149.6 ×10⁶ )³
= 3.30 x 10^9 kg/m^3
Therefore, the average density of the giant's envelope is approximately 3.30 x 10^9 kg/m^3.

what would be your first step in completely factoring 6a^2-15a+6
The completely factoring form of 6a^2 - 15a + 6 is 3(2a - 1)(a - 2).
To completely factor the expression 6a^2 - 15a + 6, the first step is to check if there is a common factor among the coefficients (6, -15, and 6) and the terms (a^2, a, and 1).
In this case, we can see that the common factor among the coefficients is 3, so we can factor out 3:
3(2a^2 - 5a + 2)
Now we need to factor the quadratic expression inside the parentheses further. We are looking for two binomials that, when multiplied, give us 2a^2 - 5a + 2. The factors of 2a^2 are 2a and a, and the factors of 2 are 2 and 1. We need to find two numbers that multiply to give 2 and add up to -5.
The numbers -2 and -1 fit this criteria, so we can rewrite the expression as:
3(2a - 1)(a - 2)
Therefore, the completely factored form of 6a^2 - 15a + 6 is 3(2a - 1)(a - 2).

You roll a 6-sided die two times. What is the probability of rolling a 4 and then rolling a 2? (Write your answer as a fraction or whole number.)
Answer:
1/36
Step-by-step explanation:
On the first throw, the probability of rolling any particular number, 1 through 6, is 1 out of 6. So the chance of rolling a 4 is 1/6.
On the second roll, your probability of rolling a 2 is 1/6.
The 'trick' is knwoing what to do with those two numbers.
Here's the rule: If events are dependent on one another, you multiply the probabilities.
Any time you see a scenario where X has to happen and then some other thing (X, Y, or whatever) has to happen, the events are dependent.
Probability of rolling a 4 and then rolling a 2 = 1/6 * 1/6 = 1/36

help?? would really appreciate it! (i highly dislike being bad at math)
Step-by-step explanation:
Put both of the equations into y = mx + b form to compare them
m = slope if they have the same slope they are parallel and do not intersect
b = y axis intercept
if m and b are equal in each of the equations , they are the same line
2x+y = 0 ======> y = - 2x + 0
2y = -4x + 6 ====> y = - 2x + 3
The both have the same slope = -2 so they are parallel
but they have different b values so they are not the same lines
No intersection means no solution : parallel lines do not intersect

SOURCE Tax INCOME Loans ASC QP Other income Non-tax income AMOUNT (in billion rand) 1370 242.7 180.3 31.5 EXPENDITURE SECTOR Social Development Basic Education Health Peace and safety Economic development Community Development Debt service cost AMOUNT (in billion rand) Further Education and Training Other 278.4 262.4 222.6 211.0 209.2 208.5 202.2 APRIL 2021 112.7 B 1823.72 TOTAL A Write the amount received from loans as a number in millions (1) (3) (3) Calculate the missing value A Calculate the missing value B. Show ALL calculations. Determine the amount allocated for Community Development as a percentage of the total expenditure. (4)
The amount received from loans as a number in millions is 242,700 million rand.
How to calculate the valueDeducing value A requires computation of collective income sources, for which the following summation suffices:
Total Income = Tax + Loans + ASC + QP + Other income + Non-tax income = 1370 + 242.7 + 180.3 + 31.5 + A + 0 = 1825.5 + A
In this context, it follows that A amounts to (1825.5 - 1370 - 242.7 - 180.3 - 31.5) = 0 million rand.
Conversely determining missing value B necessitates subtraction of total expenditure from accumulated revenue, giving rise to the subsequent formula:
Total Income - Total Expenditure = B
(1825.5 - 112.7 - 278.4 - 262.4 - 222.6 - 211.0 - 209.2 - 208.5 - 202.2 - 0) = B
Following calculation, B equates to -77.1 million rand, indicating an overage in expenses during fiscal year 2019/20.

Write a sentence of the form “–––––––––––––– is a function of –––––––.”
Type your response in the space below.
"Distance traveled is a function of time." In the context of motion or travel, the distance traveled is often dependent on the amount of time that has passed.
Distance is a fundamental concept in physics and mathematics that measures the extent or length between two points.
It represents the amount of ground covered or space traveled. When we say that distance is a function of various factors, it means that different variables or parameters can influence the distance traveled.
In the context of motion or travel, the distance traveled is often dependent on the amount of time that has passed.
The sentence "Distance traveled is a function of time" expresses this relationship, indicating that the distance traveled can be determined or calculated based on the value of time.
Thus, it implies that as time changes, the corresponding distance traveled also changes, establishing a functional relationship between the two variables.

What is the area of a triangle whose vertices are X(1, 1), Y(3, -1), and Z(4,4)?
Answer:
Step-by-step explanation:
Note that in this diagram, point A represents point X, point B represents point Y, and point C represents point Z.
From the diagram, it appears as if \(\overline{XZ} \perp \overline{XY}\). To determine if this is the case, we can find the slopes of both segments.
\(m_{\overline{XZ}}=\frac{4-1}{4-1}=1\\m_{\overline{XY}}=\frac{-1-1}{3-1}=-1\)
Since these slopes are negative reciprocals, we know that they are perpendicular.
This means we can use the formula \(A=\frac{1}{2}bh\), where b is the base (XY) and h is the height (XZ).
Note these are interchangeable.Using the distance formula,
\(XY=\sqrt{(3-1)^{2}+(-1-1)^{2}}=2\sqrt{2}\\XZ=\sqrt{(4-1)^{2}+(4-1)^{2}}=3\sqrt{2}\)
This means the area is \(\frac{1}{2}(2\sqrt{2})(3\sqrt{2})=\boxed{6}\)
Given the triangle ABC at points A = ( 2, 2 ) B = ( 4, 5 ) C = ( 6, 3 ), and if the triangle is first reflected over the y axis, and then over the x axis, find the new point A''.
To reflect a point over the y-axis, we negate the x-coordinate of the point. To reflect the resulting point over the x-axis, we negate the y-coordinate of the point. So, to find the new point A'', we can perform these operations on the original point A:
1. Reflect A over the y-axis to get A': (-2, 2)
2. Reflect A' over the x-axis to get A'': (-2, -2)
Therefore, the new point A'' is (-2, -2).

Since we're dealing with fractions, the total fraction is 1
Mortgage =1/3
Food =1/6
Fraction of income left=x
So we equate everything above to 1
\( \frac{1}{3} + \frac{1}{6} + x = 1\)
\( \frac{1}{3} + \frac{1}{6} + x = 1 \\ lcm = 6 \\ multiply \: each \: term \: by \: 6 \\ 6 \times \frac{1}{3} + 6 \times \frac{1}{6} + 6(x) = 6(1) \)
