Answer:
5.21 * 10^4.
Step-by-step explanation:
There are 4 more digits after the 5 so it is:
5.21 * 10^4.
[tex]52100 = 521 \times {10}^{2} = \\ [/tex]
[tex]5.21 \times {10}^{2} \times {10}^{2} = 5.21 \times {10}^{4} = \\ [/tex]

Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The distance is 12 because all you have to do is add the -7 and the 5 (drop the negative add it as if it's 7 and 5) and that'll give you 12.

Look at the figure. How can you prove the triangles are congruent?
A. ∆ABD ≅ ∆CDB by the SAS Postulate.
B, It is not possible to determine if the triangles are congruent.
C. ∆ABD ≅ ∆CDB by the SSS Postulate.
Answer:
A. ∆ABD ≅ ∆CDB by the SAS Postulate.
Step-by-step explanation:
You know lines AB and DC are congruent because of the lines on each. Additionally, angles B and D are congruent for the alternative interior angles rule and they also are marked as congruent in the image. Finally, DB is congruent to DB because of the reflexive property. So you have two sides and the included angle, this makes the SAS postulate true.
Answer:
the answer is A

A line segment that forms a right angle with another segment at its midpoint
is a
A. angle bisector
B. perpendicular bisector
C. regular polygon
D. rectangle
Answer:
B
Step-by-step explanation:
Please mark brainliest if I helped.
A line segment that forms a right angle with another segment at its midpoint is a perpendicular bisector.
Option B is the correct answer.
What is a line segment?A line segment is part of a line that is bounded by two distinct endpoints and contains every point on the line between its endpoints.
It can be measured by its length and is finite in size.
We have,
A perpendicular bisector is a line or line segment that cuts another line segment into two equal parts and forms a right angle with it.
The midpoint of the line segment is the point where the perpendicular bisector intersects it.
Therefore, if a line segment forms a right angle with another segment at its midpoint, it is a perpendicular bisector since it cuts the segment into two equal parts and forms a right angle with it.
Thus,
A line segment that forms a right angle with another segment at its midpoint is a perpendicular bisector.

what are the y values of the equation y = 3x + 4 at x values -1, 0, 1, 2
Answer:
-2; 1; 4; 7
Step-by-step explanation:
To solve for y, plug the x value in to the expression
y = 3(-1) + 1
y = -3 + 1
y = -2
When x = -1, y = -2
y = 3(0) + 1
y = 0 + 1
y = 1
When x = 0, y = 1
y = 3(1) + 1
y = 3 + 1
y = 4
When x = 1, y = 4
y = 3(2) + 1
y = 6 + 1
y = 7
When x = 2, y = 7

A wall measures 2 meters 30 centimeters in width.
What is the width of the wall in millimeters?
A:0.0023 mm
B:0.23 mm
C:2.3 mm
D:2,300 mm
Answer:
The answer is D
Step-by-step explanation:
1 meter = 1,000 millimeters
1 centimeter = 10 millimeters
2 meters = 2,000 millimeters
30 centimeters = 300
2,000+30=2,300
Answer: D. 2,300
Step-by-step explanation:
There is 1000 millimeters in a meter which gets you 2000 plus the 30 centimeters. 30 centimeters is equal to 300 millimeters because for every centimeter its 10 millimeters. Add the 2000 to the 300 and get 2300 millimeters.

squares of side x are cut from each corner of an 8 inches x 5 inch in rectangle, so that its sides can be folded to make a box with no top. define a function in terms of x that can represent the area of the base of the box
Answer:
When we do not have anything cut of the rectangle, the area is:
8in*5in = 40in^2.
Now, when we cut squares of length x in the corners, the measures of the base will be:
8in - 2*x
5in - 2*x
We subtract two times x in each case because we cut the squares in the four corners. (below you can see a drawing of this situation, where the doted rectangle is the area that we want to calculate)
Then the area as a function of x is:
A = (8in - 2*x)(5in - 2*x) = 40in^2 + 4*x^2 - 26*x
The width of a slot of a duralumin forging is (in inches) normally distributed with μ= 0.9000 and σ = 0.0030. The specification limits were given as 0.9000 ±0.0050. Show your calculations. Draw normal curves wherever appropriate.
a) What percentage of forgings will be defective?
b) What is the maximum allowable value of σ that will permit no more than 1 in 100 defectives when the widths are normally distributed with μ = 0.9000 and σ (revised value)?
Answer:
a) 9.56%
b) 0.0019
Step-by-step explanation:
a) Find the z-scores.
z = (x − μ) / σ
z₁ = (-0.0050) / 0.0030
z₁ = -1.67
z₂ = (0.0050) / 0.0030
z₂ = 1.67
Find the probability using a chart or calculator.
P(Z < -1.67 or Z > 1.67) = 2 P(Z < -1.67)
P(Z < -1.67 or Z > 1.67) = 2 (0.0478)
P(Z < -1.67 or Z > 1.67) = 0.0956
b) Use a chart or calculator to find the z-score.
P(Z < -z or Z > z) = 0.01
P(Z < -z) = 0.005
z = 2.576
Find the standard deviation.
z = (x − μ) / σ
2.576 = (0.0050) / σ
σ = 0.0019

Answer:
rate of change formula is (y2-y1)/(x2-x1)
so (36-24)/(7.5-5)= 12/2.5=4.8lbs
So for every 4.8lbs you give an extra mL of dosage
Answer: A) rate of change formula is (y2-y1)/(x2-x1)
so (36-24)/(7.5-5)= 12/2.5=4.8lbs.

Which inequality represents the graph shown below?
A number line between negative 5 and 5 is shown with an open circle at negative 2 and a ray drawn to the right of negative 2.
A. x –2
D. x ≥ –2
Answer:
x > -2
Step-by-step explanation:
An open circle (unshaded) which starts at -2 and drawn to the right means that the possible values of x do not include -2. Possible values of x are greater than -2, upwards.
Therefore, the inequality to use in representing the information displayed by the graph is x > -2.
This means possible values of x are greater than -2.
