What is the equation of the line in point slope form
Answer:
y=x-40
Step-by-step explanation:
solve the system y= 4x + 1 and 3x+2y =13
Given :

Write an exponential function y = abx whose
graph passes through the points (1,6), (2, 18)
Answer:
[tex]2(3) {}^{x} [/tex]
Step-by-step explanation:
[tex]y = ab {}^{x} [/tex]
We know that when x=1, y=6
[tex]6 = a {b}^{1} [/tex]
x=2, y=18
[tex]18 = a {b}^{2} [/tex]
Notice that if we divide
[tex] \frac{ {ab}^{2} }{ab} = b[/tex]
So if we divide 18 and 6, that will give us our common ratio.
[tex] \frac{18}{6} = 3[/tex]
So our common ratio is 3.
So know we have
[tex]a(3) {}^{x} [/tex]
Plug in one of the points to find a.
[tex]6 = a(3)[/tex]
[tex]a = 2[/tex]
So the equation. we have

Given u = (2, -8) and v = (8, -2), what is u times v?
Answer:
[tex]u\cdot v=32[/tex]
Step-by-step explanation:
Assuming [tex]u[/tex] and [tex]v[/tex] are vectors, their dot product is [tex]u\cdot v[/tex] where [tex]u_1v_1 + u_2v_2[/tex]:
[tex]u\cdot v=u_1v_1+u_2v_2=(2)(8)+(-8)(-2)=16+16=32[/tex]
Therefore, [tex]u\cdot v=32[/tex]
The probability of an event is 84%. Describe the likelihood of the event.
Answer:
Please read below.
Step-by-step explanation:
P(event)= favorable outcomes / total outcomes
0.84 * 100 = 84
100 - 84 = 16
84 favorable outcomes
16 unfavorable outcomes
100 total outcomes
Therefore there is a 84% chance of it happening.
Therefore there is a 16% chance of it not happening.
P(event) = 84/100
8.4 out of 10
Describe it how ever you want. 8.4 out of 10 is a pretty good bet to me. I would put my money on it. There isn't a lot of context to the question. But, I hope this helps!
It means 840 times out of 1000 times, an event is likely to happen or in other words, there is an 84% chance of happening an event.
What is probability?Probability is to measure the occurrence of an event.
It is given that
probability of an event = 84% or 0.84
This means, P(E) = 0.84
Number of favorable outcomes/ Total outcomes =84
Let us say Total outcomes are 1000
So favorable outcomes = 1000*0.84
Favorable outcomes = 840
Therefore, It means 840 times out of 1000 times, an event is likely to happen or in other words, there is an 84% chance of happening an event.

Please helpp me?!!!! I will fail my Calc class!!
Step-by-step explanation:
Using that fact that,
[tex] \cos(u) = \frac{x}{r} [/tex]
and
[tex] {r}^{2} = {x}^{2} + {y}^{2} [/tex]
We need to find sin which that formua is
[tex] \sin(u) = \frac{y}{r} [/tex]
We know what r and x is so we need to find y.
[tex] {8}^{2} = { - 3}^{2} + {y}^{2} [/tex]
[tex]64 = 9 + {y}^{2} [/tex]
[tex]55 = {y}^{2} [/tex]
[tex] \sqrt{55} = y[/tex]
Sin is positve on the interval pi/2 to pi. so we get
[tex] \sin(u) = \frac{ \sqrt{55} }{8} [/tex]
b.
[tex] \tan(u) = \frac{y}{x} [/tex]
so
[tex] \tan(u) = - \frac{ \sqrt{55} }{3} [/tex]
c.
[tex] \sec(u) = \frac{r}{ x} [/tex]
[tex] \sec(u) = - \frac{8}{3} [/tex]
d.
[tex] \sin(2u) = 2 \sin(u) \cos(u) [/tex]
[tex]2 ( \frac{ \sqrt{55} }{8} )( - \frac{3}{8} ) = \frac{ - 6 \sqrt{55} }{64} = \frac{ - 3 \sqrt{55} }{32} [/tex]
e.
[tex] \cos {}^{} (2u) = \cos {}^{2} (u) - \sin {}^{2} (u) [/tex]
[tex]( \frac{ - 3}{8} ) {}^{2} - ( \frac{ \sqrt{55} }{8} ) {}^{2} = \frac{ - 46}{64} = - \frac{23}{32} [/tex]

What is the LEADING COEFFICIENT of the polynomial: 2x^2y - 7x^2y^3 + 6xy^2
Answer:
-7
Step-by-step explanation:
Leading coefficient: the number written in front of the variable with the largest degree.
If a term has two or more variables, its degree is the sum of the exponents of its variables
For [tex]2x^2y - 7x^2y^3 + 6xy^2[/tex]
The degree of the first term of the polynomial is 3 (2 + 1 = 3)The second term of the polynomial is of degree 5 (2 + 3 = 5)The third term of the polynomial is of degree 3 (1 + 2 = 3)Therefore, the leading coefficient is -7 since the greatest sum of the exponents is of the second term.
[tex]\mathbb{FINAL\;ANSWER:}[/tex]
[tex]\huge\boxed{\sf{The\;coefficient\;is\;-7}}[/tex]
[tex]\mathbb{SOLUTION\;WITH\;STEPS:}[/tex]
Hi! Hope you are having a nice day!
The leading coefficient of the given polynomial is -7.
Why? Because the leading coefficient is the number written before the variable with the largest exponent.
In this case, it's -7, because it's written next to a term that's cubed, and that's the largest exponent in the polynomial.
Also, if a term has two variables (or more) then we add the exponents in that term in order to get the degree of the term.
In this case, it's 5.
Hope you could understand everything.

Answer:
m∠R = 60°
explanation:
Its a isosceles triangle, thus m∠R = m∠Ptotal interior angles of triangle sum up to 180°Let the angle be x,
x + x + 60° = 180°
2x = 180° - 60°
2x = 120°
x = 60°
Answer:
Step-by-step explanation:
Sum of interior angles in a triangle = 180degree
PQ=QR so triangle PQR is an isosceles triangle
The two base angles of an isosceles triangle are equal
So <R = <P
m<R + m<P + 60degree = 180degree
m<R = (180-60)/2 = 60degree

In 1949, the inflation rate in the United States was -2%If a car cost $1500 at the beginning of the year, what did it cost at the end of the year
Based on the inflation rate in the United States in 1949, the cost of the car at the end of the year would be $1,470.
What is the cost of the car at year's end?The cost can be found by the formula:
= Cost x (1 + inflation rate)
The inflation rate is negative so solving gives:
= 1,500 x (1 - 2%)
= $1,470

-16
0-2
O 8

Step-by-step explanation:
g(f(x)) = g(3x² - 4) = 2(3x² - 4) - 6
so
g(f(2) = 2(3*2² - 4) - 6 = 2*8 - 6 = 16 - 6 = 10

What is the value of X?
Solution:
Note that:
3x + 50 = 6x - 10 (Vertically opposite angles)Simplify the equation to find x.
Add 10 both sides.
3x + 50 = 6x - 10=> 3x + 50 + 10 = 6x - 10 + 10=> 3x + 60 = 6xSubtract 3x both sides.
3x + 60 = 6x=> 3x - 3x + 60 = 6x - 3x=> 60 = 3xDivide 3 both sides.
60 = 3x=> 60/3 = 3x/3=> x = 20Answer:
x = 20Step-by-step explanation:
opposite angles = equal angles
we solve with a proportion
3x + 50 = 6x - 10
50 + 10 = 6x - 3x
60 = 3x
x = 60 : 3
x = 20
