log⁵(1/125)=?
solve this for me
Answer:
by the way am learning it.for more and other answer follow me
Step-by-step explanation:
log5 1/125 = x
Rewrite log5 1/125 :
1/125 = 125^-1
This gives:
log 5 (125^-1) , bring down the power
-1 (log5 125) , rewrite 125 in term of power of 5
-1 (log5 (5^3), again bring down the power
(-1*3)(log5 5), note log5 5 = 1
Answer: x = -3
The average temperature in Lincoln in July is 85 degrees. Last Wednesday, it was 90 degrees. Today it was 15 degrees cooler than last Wednesday. What was the temperature today?
Answer:
[tex]75^{\circ}\text{F}[/tex]
Step-by-step explanation:
Last Wednesday it was 90 degrees Fahrenheit.
Today it is 15 degrees Fahrenheit colder than it was last Wednesday.
So, today's temperature will be the difference of the temperatures of last Wednesday's and today's temperature. We have to find the difference as it is colder today means it is a lower temperature than last Wednesday's.
[tex]90-15=75^{\circ}\text{F}[/tex]
Today's temperature is [tex]75^{\circ}\text{F}[/tex]

A
B
X=
Answer:
x=34
Step-by-step explanation:
m is a perpendicular bisector that basically cuts ab right down the middle creating two equal parts
using this info, u now know that 3x+77 and 6x+25 are equal to each other
3x+77=6x-25
77=3x-25
102=3x
x=34

what is the correct answer?
Given:
The function is
[tex]f(x)=(x+3)^2(x-5)^6[/tex]
To find:
The zeros of the given function.
Solution:
The general form of polynomial is
[tex]P(x)=a(x-c_1)^{m_1}(x-c_2)^{m_2}...(x-c_n)^{m_n}[/tex] ...(i)
where, a is a constant, [tex]c_1,c_2,...,c_n[/tex] are zeros of respective multiplicities [tex]m_1,m_2,...,m_n[/tex].
We have,
[tex]f(x)=(x+3)^2(x-5)^6[/tex]
On comparing this with (i), we get
[tex]c_1=-3,m_1=2[/tex]
[tex]c_2=5,m_2=6[/tex]
It means, -3 is a zero with multiplicity 2 and 5 is a zero with multiplicity 6.
Therefore, the correct option is B.
Heather buys 12 patio chairs for $366. Each chair costs the same amount. Part A Which equation represents the best estimate for the cost of each chair?
Answer:
[tex]C=\dfrac{366}{12}[/tex] = $30.5
Step-by-step explanation:
It is given that,
The cost of 12 patio chairs is $366.
We need to find the equation that represents the cost of each chair.
As each chair costs the same amount. It means we can find the cost of each chair by dividing total cost of 12 chairs divided by 12 i.e.
[tex]C=\dfrac{366}{12}[/tex]
So, it is the required equation. If we solve it, we get $30.5. Hence, the cost of each chair is $30.5
Write the equation of the line passing through the points (2,-5) (3,-1)
Answer:
they give you two points... so use the point slope formula with one on the points
y - y1 = m ( x - x1)
Step-by-step explanation:
find the slope m
m = y2 -y1 / x2-x1
from the given.. x1=2 and y1 = -5
x2 = 3 and y2 = -1 then,
m = -1 -( -5) / 3 - 2
m = 4/1
m = 4
now plug in to the point slope formula either of the points... I'll use the 1st point
y - 2 = 4(x -(-5))
y -2 = 4(x +5)
y -2 = 4x +20
y = 4x +22

Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x−7)?
The graph of g(x) is the graph of f(x) translated 7 units down.
The graph of g(x) is the graph of f(x) translated 7 units left.
The graph of g(x) is the graph of f(x) translated 7 units right.
The graph of g(x) is the graph of f(x) translated 7 units up.
Step-by-step explanation:
When the number is inside the parenthesis. It means horizontal shift. Now negative is to the right and positive is to the left. Since it is negative 7 it would be 7 units to the right
any more help just ask :)

the equation of the line through (3 -4) with slope 2/3 is:
WILL GIVE BRAINLIST
Answer:
[tex]y = \frac{2}{3}x - 6[/tex].
Step-by-step explanation:
(3 , -4) ; slope(m) = 2/3
y - y1 = m (x -x1)
[tex]y - [-4] = \frac{2}{3}(x - 3)\\\\y + 4 = \frac{2}{3}x - 3*\frac{2}{3}\\\\y +4 = \frac{2}{3}x-2\\\\ y = \frac{2}{3}x - 2 - 4\\\\ y = \frac{2}{3}x - 6[/tex]

Grandma gave 13 pieces of jewelry and grandma fien gave y pieces to the sister to divide evenly among them selves.There are 5 sister
Complete question :
Grandma gave 13 pieces of jewelry and grandma fien gave y pieces to the sister to divide evenly among them selves.There are 5 sister. How many pieces of jewelry does each sister get
Answer:
(13 + y) / 5
Step-by-step explanation:
Given that :
Number of jewelries Given by grandma = 13
Number of jewelries Given by grandma fien = y
Total number of jeweleries Given = (13 + y)
Number of people among which the jeweleries is to be divided = 5
Hence, since the distribution is to be even, then, each sister gets :
Total jeweleries / number of sisters
(13 + y) / 5

The answer choices are..
-2
5
-5
2
0 -5
2.
Answer:
(x,y)=(-1,1)
Step-by-step explanation:
Given that,
3x + 5y = 2 .....(1)
6x - 10y = -16 ....(2)
Finding the value of x from equation (1).
[tex]x=\dfrac{2-5y}{3}[/tex]
Put the value of x in equation (2)
[tex]6(\dfrac{2-5y}{3}) - 10y = -16\\\\2(2-5y)-10y=-16\\\\4-10y-10y=-16\\\\-20y=-16-4\\\\y=1[/tex]
Put the value of y in equation (1) :
[tex]3x + 5(1) = 2\\\\3x=2-5\\\\3x=-3\\\\x=-1[/tex]
So, the solution of the equations is (-1,1).
decide whether or not it is a function.

Suppose you have a bag containing 2 black marbles and 3 red marbles. You reach into the bag, select a marble, see what color it is and replace it in the bag. Then you repeat this process a second time. What is the probability of picking a red marble both times?
Answer:
[tex]\dfrac{9}{25}[/tex]
Step-by-step explanation:
Given that the bag contains black and red marbles.
Number of black marbles in the bag = 2
Number of red marbles in the bag = 3
Total number of marbles in the bag = Number of black marbles + Number of red marbles = 2 + 3 = 5
Let us have a look at the formula for probability of an event E, which can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
[tex]P(\text{First red marble}) = \dfrac{\text{Number of red marbles}}{\text{Total number of marbles}} = \dfrac{3}{5 }[/tex]
Now, the marble chosen at first is replaced.
Therefore, the count remains the same.
[tex]P(\text{Second red marble}) = \dfrac{\text{Number of red marbles}}{\text{Total number of marbles}} = \dfrac{3}{5}[/tex]
Now, the required probability can be found as:
[tex]P(\text{First red marble})\times P(\text{Second red marble}) = \dfrac{3}{5}\times \dfrac{3}{5} = \bold{\dfrac{9}{25} }[/tex]
An angle measures 29.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
104.6 deg, 75.4 deg
Step-by-step explanation:
One angle measures x.
The other angle measures 29.2 deg less than x, so it measures x - 29.2.
They are supplementary angles, so the sum of their measures is 180 deg.
x + x - 29.2 = 180
2x - 29.2 = 180
2x = 209.2
x = 104.6
x - 29.2 = 75.4
Answer: 104.6 deg, 75.4 deg
