please help me answer this question.. am giving brainliest
Step-by-step explanation:
We are going to use the following properties of logarithms to solve this problem:
[tex]\log{\dfrac{a}{b}} = \log{a} - \log{b}[/tex]
and
[tex]\log{ab} = \log{a} + \log{b}[/tex]
So we can rewrite the given equation as
[tex]\log{2x^3} - \log{x} = \log{\left(\dfrac{2x^3}{x}\right)} = \log{2x^2}[/tex]
Also,
[tex]\log{16} + \log{x} = \log{(16x)}[/tex]
So we can write
[tex]\log{2x^2} = \log{(16x)}[/tex]
or eliminating the log symbols, we get
[tex]2x^2 = 16x[/tex]
The solutions for the equation above are
[tex]x = 8\:\text{and}\: 0[/tex]
Really need help quick
Answer:
Total Number of times Spun = 1200
Key sentence: "Pr(Red) is same as Pr(Yellow).
Pr(Green)= 0.2
0.2 = x/1200
x= 0.2 x 1200
x = 240.
It landed on green 240 times
Pr(Brown) =0.54
0.54 = y/1200
y= 1200 x 0.54
y= 648.
Now
To get the Number of times it landed on Red and Yellow
You simply subtract that of Green and Brown from 1200 and divide this result by 2(Since Red and Yellow are have equal occurrence).
1200 – (648 + 240)
= 312.
312/2 = 156.
So It landed on Red and Yellow 156 times each.
Step-by-step explanation:
Red ----- 156times
Green -----240times
Brown ----- 648times
Yellow -----156times
Two angles are supplementary. One angle measures 52 degrees more than the other angle. Find the measure of the LARGER angle.
[tex]\begin{array}{l}\text{We\ have\ } \alpha +\beta =180\ \text{and} \ \beta =\alpha +52\text{\ then}\\\\\alpha +\alpha +52=180\\\\\Longrightarrow 2\alpha =180-52\\\\\Longrightarrow \alpha =\frac{128}{2} =64\\\\\therefore \beta =64+52=116\\\\\therefore \boxed{\text{The\ larger\ angle\ is\ 116\ degrees}}\end{array}[/tex]
I need help with number 3 plzzz fast
Step-by-step explanation:
the domain is the interval of the x (input) values.
in other words, is g(x) invalid for certain x ?
it does not look like it. it looks like g(x) is valid for every possible value of x from -infinite to +infinite.
the range is the interval of possible y (functional) values.
and that is clearly valid for every y between -1 and +infinity.

if Angle 1 and angle 2 are complementary, angle 1 = (6.c + 3) and angle 2 = (4x + 7) , what does angle 2 =?
39
60
8
51
Answer:
C
Step-by-step explanation:
They are complementary which means they add to 90. I take it that the c is a typo and you meant x
6x + 3 + 4x + 7 = 90 Combine like terms.
10x + 10 = 90 Subtract 10 from both sides
10x = 90 - 10
10x = 80 Divide by 20
x = 80/10
x = 8

Answer: Choice B
[tex]\frac{1}{\sqrt{65}}<-4, 7>[/tex]
===============================================================
Explanation:
Consider a right triangle with legs a = 4 and b = 7. Through the pythagorean theorem, the hypotenuse is
c = sqrt(a^2+b^2) = sqrt(4^2+7^2) = sqrt(65)
This represents the length of the vector <-4,7>
Dividing each component by the length will normalize the vector. This is the same as multiplying by [tex]\frac{1}{\sqrt{65}}[/tex] which is what choice B shows. The phrasing "normalize the vector" means "make the vector to be of length 1". A common application of normalizing vectors will come up in computer graphics.
The original vector and the vector mentioned in choice B point in the same direction. The only thing that has changed is the length from sqrt(65) to 1.

3) A bullet travels 2400 feet per second. Write this in miles per hour, rounded to the nearest
whole mile per hour. Reference: 1 mile = 5280 feet
Answer:
1636mi/hr
Step-by-step explanation:
2400ft/s = _______mi/hr 1 hr = 3600s 1mi = 5280ft
2400ft/s x 3600s/hr x 1mi/5280ft = 1636mi/hr

2. Given that tan 25º = a, express each of the following in terms of a.
tan 205
sin 25°
cos 65
cos 245
9514 1404 393
Answer:
tan(205°) = asin(25°) = (a√(a²+1))/(a²+1)cos(65°) = (a√(a²+1))/(a²+1)cos(245°) = -(a√(a²+1))/(a²+1)Step-by-step explanation:
The tangent function is periodic with a period of 180°. So ...
tan(205°) = tan(25°) = a
__
The identity relating sine and tangent is ...
sin(x) = tan(x)/√(tan²(x)+1)
Rationalizing the denominator gives ...
sin(x) = tan(x)√(tan²(x)+1)/(tan²(x)+1)
sin(25°) = a√(a²+1)/(a²+1)
__
cos(65°) = sin(25°) = a√(a²+1)/(a²+1)
__
cos(245°) = -sin(25°) = -a√(a²+1)/(a²+1)

Triangle ABC has coordinates A(-4,1), B(0,-2),and C(4,1).
The perimeter of ∆ABC is ___ units.
9514 1404 393
Answer:
18 units
Step-by-step explanation:
The distance formula is used to find the distance between two points:
d = √((x2 -x1)² +(y2 -y1)²)
For AB, the distance is ...
d = √((0 -(-4))² +(-2 -1)²) = √(16 +9) = √25 = 5
The distances between the other pairs of points can be found the same way. We have elected to let a spreadsheet do the math. It tells us the perimeter of triangle ABC is 18 units.

plus an additional $2 per mile driven. How
long is a cab ride that costs $11?
miles
Answer:
The answer is c = 2 + 3d .
Step-by-step explanation:
It is given that a cab ride cost $2 which is a fixed amount and charges additional $3 per mile. So you have to make an equation of c in terms of d :
Let c be the cost,
Let d be the distance,
c = 2 + 3d

Josef has $300 to spend. Which inequality could help him find the maximum number of gifts, x, he could buy if he needs $215 to fix his car and then wants to spend $15 on each gift?
Answer:
x = (300 - 215)/15
Step-by-step explanation:
x, the amount of gifts, is equal to the amount of money left over after he fixes his car, divided by the amount he's willing to spend on each gift.
josef could buy a maximum of 5 gifts! the answer is 5.6 but he can't buy half a gift, nor can he afford 6, so we round down to get 5 gifts :)
