Step-by-step explanation:
Using the rule of exponents
[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]
Given
3 × [tex]10^{-2}[/tex]
= 3 × [tex]\frac{1}{10^{2} }[/tex]
= 3 × [tex]\frac{1}{100}[/tex]
= [tex]\frac{3}{100}[/tex] = 0.03
how do i do this? -X= 8
Answer:
x = -8
Step-by-step explanation:
-X= 8
Multiply by -1
-X*-1= 8*-1
x = -8
Answer:
x = -8
Step-by-step explanation:
Multiply both side of the equation by -1
-x(-1) = 8(-1)
On the x side, the negatives cancel each other out, making x positive.
On the 8 side, the negative makes the 8 into -8.
x = -8
(essentially, switch the negative/positive signs)
Find the distance between (-4,5) and (4,0) round to the nearest hundredth
Answer:
Solution: 9.43
Step-by-step explanation:
Remember that we can determine the distance between any two points using the distance formula, d = √(x₂ - x₁)² + (y₂ - y₁)². Let's substitute known values to determine the distance:
[tex]\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2},}\\ \\\\\mathrm{d}= \sqrt{(4 - (-4))^2 + (0 - 5)^2} = \sqrt{(4 + 4)^2 + (- 5)^2} \\= \sqrt{(8)^2 + 25} = \sqrt{64 + 25} = \sqrt{89}[/tex]
Hence the distance between the points (-4,5) and (4,0) is exactly √89. The question asks us to round off to the nearest hundredth, so your solution will be approximated off to two digits → 9.43.

Point B lies on AC between A and C. If AB = 8 and AC = 10, find BC.
A. 2
B. 8
C. 10
D. 18
Answer:
BC = 2
Step-by-step explanation:
If B lies on AC it makes the line segments AB and BC.
AC=10
AB+BC=AC
AB+BC=10
8+BC=10
BC=2
The value of BC is 2 which is the correct answer that would be an option (A).
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment AC , where the length of line segment AC refers to the distance between its endpoints, A and C.
Point B lies on AC between A and C.
A______________B______________C
Given that B lies on AC it makes the line segments AB and BC.
AB = 8 and AC = 10
⇒ AB + BC = AC
⇒ AB + BC = 10
⇒ 8 + BC = 10
⇒ BC = 2
Therefore, the value of BC is 2 which is the correct answer that would be an option (A).

A rock has a density of 4.56 g/mL. If it weighs 235 g, what is its volume?
Answer:
51.54mL
Step-by-step explanation:
Density can be defined as the mass per unit volume of a particular object , substance or compound.
Density tell us how heavy or dense that object, substance or compound is.
Mathematically, the formula for Density = Mass(grams)/Volume(ml or cm³)
In the above question, a rock has the following criteria:
Density = 4.56 g/mL.
Mass = 235 g
Volume is unknown.
Imputing this values into the formula for Density, we have:
4.56g/mL = 235g/ Volume
Cross Multiply
4.56g/mL × Volume = 235g
Volume = 235g/4.56g/mL
Volume = 51.535087719mL
Approximately, the volume of the rock to 2 decimal places = 51.54mL

Step-by-step explanation:
am i right with the question and if i m can you explain further i think i awser is y=10x
You are correct.
C is the constant, which is also called the slope.
Slope = change in y over the change in x:
Slope = 160-30 / 16-3 = 130/13 = 10
The equation would be y = 10x

The picture shows the Alamillo bridge in Seville, Spain. In the picture m<1=58 and m<2=24. Find the measure of the supplement of <1= and of <2. Someone please help!
Answer:
Supplement of <1 = 122°
Supplement of <2 = 156°
Step-by-step explanation:
Two pairs of angles are said to be supplementary, if their measures in degrees add up to give us 180°. A supplement of am angle is simply 180° - the measure of that angle.
Given that meadure of angle 1 = 58°, the supplement of angle 1 = 180° - 58° = 122°
Also, if the measure of angle 2 = 24°, the supplement of angle 2 = 180° - 24° = 156°.
Thus:
Supplement of <1 = 122°
Supplement of <2 = 156°

O a reflection in the x-axis followed by a translation down by 7 units
O a reflection in the x-axis followed by a translation up by 7 units
Answer:
a reflection in the y-axis followed by a translation down by 7 units
Step-by-step explanation:
just answered it
The transformations of the graph is a reflection in the x-axis followed by a translation down by 7 units.
Option (C) is correct.
It is required to choose the transformations of the graph.
What are transformations?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
We have a given a graph of y = f(-x) – 7.
The transformations in order are the following:
Reflection over the x-axis.
Horizontal translation of 7 units to the left.
Therefore, the transformations of the graph is a reflection in the x-axis followed by a translation down by 7 units.

A text message plan costs $2 per month plus $0.23 per text. Fine the monthly cost for x text messages
Answer:
y= 2 + 0.23x
Step-by-step explanation:
Giving the following information:
A text message plan costs $2 per month plus $0.23 per text.
First, we need to structure the total cost formula:
y= total cost
x= number of text messages
y= 2 + 0.23x
Now, we can calculate the total cost for any number of text:
x= 200
y= 2 + 0.23*200
y= $48

A. 23
B. 7
7 1 / 1
C. 9
D. 10
E. 173
Answer:
7.5
Step-by-step explanation:
8x÷4=12÷4
2x=3
x=3/2=1.5
2y+10=22
2y=12
y=6
1.5+6=7.5=7½
Answer:
7.5 or 7½
Step-by-step explanation:
8x = 12
x = 12/8 (12/4 / 8/4)
x = 3/2
x = 1.5
2y + 10 = 22
2y = 12
y = 6
1.5 + 6 = 7.5 = 7½
Which lists all of the y-intercepts of the graphed
function?
O (0,-3)
O (-1,0) and (3,0)
O (0, -1) and (0,3)
O (-1,0), (3, 0), and (0, -3)
From the graph, we can see that the graph crosses the y-axis at (0,-3) Hence, the correct answer is A (0,3).
What is the y-intercept of a function?The intersection of the graph of the function with the y-axis gives the y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
The y-intercept is where a line crosses the y-axis, so this is the point where x = 0.
From the graph, we can see that the graph crosses the y-axis at (0,-3)
Hence, the correct answer is A (0,3).

17=-5r what is the equation answer
B is incorrect so it's not the answer...
Answer:
x^2 - 4x - 3
Step-by-step explanation:
f(x) = x^2 - 6x
g(x) = -2x + 3
(f - g)(x) is the subtraction of the functions, f(x) - g(x)
You need to write it carefully using parentheses for function g(x).
(f - g)(x) = f(x) - g(x) =
= x^2 - 6x - (-2x + 3)
Now take care of the parentheses by distributing the negative sign to its left. It will change every sign inside the parentheses.
= x^2 - 6x + 2x - 3
= x^2 - 4x - 3
