Answer:
The answer is kite.
Step-by-step explanation:
Well, just looking at the definition of a kite, we can see that it lines up with Mr. Tesoro's description and drawing of the quadrilateral. A kite has one right angle that meets up witht two equal lines. The opposite pair of lines, that are much longer, don't meet up to be a right angle. The definitions line up, so there's your match; the anser is kite.
A tangent line intersecting with a radius always creates a
A tangent line intersecting with a radius always creates a right angle.
A tangent line intersects with a circle at only one point.
This point is referred to as the point of tangency.
When a radius is drawn to intersect with the tangent line at the point of tangency, then the angle at that point of intersection is a right angle i.e. the measure of the angle is 90 degrees.
This is so because both lines (i.e. the radius and the tangent line) are perpendicular lines.
Hence, the text that completes the statement is right angle.

HELP. It’s LOG form. Since were out of school I forgot how I did this and it’s due so it would be a life saver.
Answer:
see below
Step-by-step explanation:
exponent to log: [tex]a^b[/tex] = c ---> logₐc = b
ie. question 6
log ₁₀(3x+1) = 2 -----> [tex]10^{2} = 3x+1[/tex]
that will get you through questions 1 to 3, 5 to 6, and 8
in question 4, all you have to do is know that 2^2 = 4 and 2^3 = 8, by setting the bases equal, you can manipulate the exponents to get 2x+8 = 3x-3
for questions 7 and 9,
remember that:
logₐc + logₐd = logₐ(cd)
logₐc - logₐd = logₐ([tex]\frac{c}{d}[/tex])
remember change of base is [tex]log_{a} b = \frac{log_xb}{log_xa}[/tex], this will be useful if you need your calculator since calculators only have base 10 and maybe if your calculator is good enough natural base e

© Natasha can type 2600 words in 40 minutes.
Henry can type 4900 in 70 minutes.
Mark can type 3750 words in 50 minutes.
Who types at the fastest rate of words per minute?
Answer:
Mark types the fastest rate of words per minute at 75 words per minute
Step-by-step explanation:
In this question, we want to know which of the three typists has the fastest typing rate.
To calculate this, what we need to do is to divide the total number of words they can type by the number of minutes taken to type those words.
For Natasha, we have; 2600 words / 40 minutes = 65 words per minute
For Henry, we have 4900 words/70 minutes = 70 words per minute
For Mark, we have 3750 words/50 minutes = 75 words per minute
We can see that Mark with 75 words per minute has the fastest typing rate
A 10 foot ladder is leaning against the wall. The bottom of the ladder is 4 feet from the base of the wall. Which is closest to the distance from the top of the ladder to the base of the wall
Answer: 9.16 feet
Step-by-step explanation:
Hi, to answer this question, since we have formed a right triangle (see attachment) we have to apply the Pythagorean theorem:
a2 +b2 = c2
Where c is the hypotenuse of a right rectangle (the longest side) and a and b are the lengths of the other 2 sides.
In this case the hypotenuse us the ladder.
So, replacing with the values:
4^2 + b ^2 = 10^2
16 + b^2 = 100
b^2 = 100-16
b^2 = 84
b = √84
b= 9.16 feet

Answer:
[tex]28.8\%[/tex].
Step-by-step explanation:
We have been given that prices increase at a monthly rate of 2.4%. We are asked to find the percentage at which prices will increase in a year.
We know that 1 year equals 12 months.
To find the increase in one year, we will multiply monthly increase rate by 12 as:
[tex]\text{Yearly increase rate}=12\times 2.4\%[/tex]
[tex]\text{Yearly increase rate}=28.8\%[/tex]
Therefore, the prices will increase at a rate of [tex]28.8\%[/tex] in a year.

Two ducklings wander away from the nest while their mother is away. The first duckling's displacement (distance and direction) from the nest is (12,5) The second duckling's displacement is (13,-8) How much farther did the second duckling wander than the first duckling?
The magnitude of the first duckling's displacement is 13 units, and for the second duckling it is approximately 15.3 units. The second duckling wandered 2.3 units farther than the first.
Explanation:The student is asking about the displacements of two ducklings from their nest and how much farther one wandered than the other. To compare the displacements of the two ducklings, we calculate the magnitudes of their displacements using the Pythagorean theorem.
For the first duckling's displacement, with coordinates (12,5), the magnitude is
sqrt(122 + 52) = sqrt(144 + 25) = sqrt(169) = 13 units.
For the second duckling's displacement, with coordinates (13,-8), the magnitude is
sqrt(132 + (-8)2) = sqrt(169 + 64) = sqrt(233) = approximately 15.3 units.
The second duckling wandered farther by the difference in magnitudes, which is 15.3 units - 13 units = 2.3 units. Therefore, the second duckling wandered 2.3 units farther than the first duckling.

A pool company claims that for optimal results customers should use 20 cups of 73% chlorine solution to treat their pools unfortunately the company only has an 80% chlorine solution and a 60% chlorine solution In stock how many cups of Each chlorine solution should be mixed to create the optimal solution?
Answer:
13 cups of the 80% chlorine solution + 7 cups of the 60% chlorine solution
Step-by-step explanation:
The pool company recommendation is 20 cups of 73% chlorine to treat their pool
Concentration of chlorine solution in stock = 80% and 60%
Therefore to make 20 cups of 73% solution, we require;
X cups of the 80% chlorine solution and
Y cups of the 60% chlorine solution
That gives 0.8·X + 06·Y = 0.73 × 20
X + Y = 20
Solving gives X = 13 cups
and Y = 7 cups
Therefore to make the optimal solution, 13 cups of the 80% chlorine solution should be mixed with 7 cups of the 60% chlorine solution.

Step-by-step explanation:
In a quart, there are 4 cups:
1 quart = 4 cups
In 512 quarts, there will be:
4 * 512 cups = 2048 cups
If only 4 cups remained after watering, then the number of cups used to water the plants is:

It's been so hot out lately that you are thinking of throwing a bucket of water over your brother's head. You have a 2 gallon bucket, 7 quart bucket and an 18 pint bucket. Which bucket holds the most water to splash your brother with? (1 gallon = 8 pints, 1 gallon = 4 quarts, 1 quart = 2 pints)
Answer: The 18 pint bucket.
Step-by-step explanation: If you convert all of the units to gallons, you will find that the 7 quart bucket contains 1.75 gallons and the 18 pint bucket contains 2.25 gallons. Since 2.25 is the greatest amount, the 18 pint bucket contains the most water.
What is the volume of this loaf of bread, assuming that the top part of the end of the loaf is a semi-circle? Show all work.
Answer:
Step-by-step explanation:
We would section the bread into a cuboid at the bottom and a semi cylinder at the top.
Considering the bottom, the formula for determining the volume of a cuboid is expressed as
Volume = length × width × height
Therefore,
Volume = 20 × 11 × 6 = 1320 cm³
Considering the semi cylinder,
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder
h represents the height of the cylinder.
π = 3.14
Looking at the diagram,
Height = 20 cm
Diameter = 11 cm
Radius = diameter/2 = 11/2 = 5.5 cm
Since it is a semi cylinder, then
Volume = 1/2 × 3.14 × 5.5² × 20 = 949.85 cm³
Therefore, volume of this loaf of bread is
1320 + 949.85 = 2269.85 cm³

Compare the given function to the standard quadratic function f(x) = ax² + b x + c.
We get a = 2, b = 2 and c = -12
Using the quadratic formula to solve the above quadratic function
[tex]x = \dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Substitute the values of a = 2, b = 2 and c = -12 in the quadratic formula,
[tex]x = \dfrac{-2\pm\sqrt{2^2-4\times2\times-12}}{2\times2}[/tex]
[tex]x = \dfrac{-2\pm\sqrt{4+96}}{4}[/tex]
[tex]x = \dfrac{-2\pm\sqrt{100}}{4}[/tex]
[tex]x = \dfrac{-2\pm10}{4}[/tex]
x = (-2+10)/4 and x = (-2-10)/4
x = (8)/4 and x = (12)/4
x = 2 and x = 3
Therefore, the values of x would be 2 and 3 which are determined by using the quadratic formula to solve the given quadratic function.

The ratio of boys to girls in a group is 2:1. If there are 22 more boys than girls, work out how many people there are in total
Answer:
66 in total. 44 boys and 22 girls
Step-by-step explanation:
you have to multiply 22 by 2 because there is twice as many (half of two is one) boys than there is girls.
Answer:
66
Step-by-step explanation:
There is a 2:1 ratio of boys to girls, and there are 22 more boys than girls. We can assume that 2/3 of the class are boys while 1/3 of the class is girls.
The difference between the two is 1/3. This can be found by taking away the smaller of the two from the larger, in this case it's 2/3 - 1/3. Removing the third, it's 2-1 which can be done by multiplying the two fractions by three. If we add the third back by dividing by three, we get 1/3.
This means that 22 people must be equivalent to 1/3 the total class' population. If x/3 = 22, then 22 * 3 must be x.
22 * 3 = 66, so there must be 66 students in the class.
A washer and a dryer cost $713 combined. The washer costs $37 less than the dryer. What is the cost of the dryer
Answer:
375
Step-by-step explanation:
713 - 37 = 676
676 divided by 2 = 338
That would be the washer but we need to add the 37 again for the dryer
338 + 37 = 375
Which function has the same graph as y = 2cos(x + pi/4 )?
y = 2sin(x + pi/4 )
y = 2sin(x - pi/4 )
y = 2sin(x + 3pi/4 )
y = 2sin(x - 3pi/4 )
Answer:
y = 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) has the same graph of y = 2 cos (x + [tex]\frac{\pi }{4}[/tex] ) ⇒ 3rd answer
Step-by-step explanation:
Let us revise the rules of the trigonometric compound angles
cos(x + y) = cos x cos y - sin x sin y
sin(x + y) = sin x cos y + cos x sin y
Let us solve the problem using the rules above
y = 2 cos (x + [tex]\frac{\pi }{4}[/tex] )
∵ 2 cos (x + [tex]\frac{\pi }{4}[/tex] ) = 2[cos x cos [tex]\frac{\pi }{4}[/tex] - sin x sin [tex]\frac{\pi }{4}[/tex] ]
∵ cos [tex]\frac{\pi }{4}[/tex] = [tex]\frac{\sqrt{2}}{2}[/tex] and sin [tex]\frac{\pi }{4}[/tex] = [tex]\frac{\sqrt{2}}{2}[/tex]
- Substitute them in the right hand side
∴ 2 cos (x + [tex]\frac{\pi }{4}[/tex] ) = 2[ [tex]\frac{\sqrt{2}}{2}[/tex] cos x - [tex]\frac{\sqrt{2}}{2}[/tex] sin x]
- Multiply the bracket in the right hand side by 2
∴ 2 cos (x + [tex]\frac{\pi }{4}[/tex] ) = [tex]\sqrt{2}[/tex] cos x - [tex]\sqrt{2}[/tex] sin x
∴ y = [tex]\sqrt{2}[/tex] cos x - [tex]\sqrt{2}[/tex] sin x
Now let us find the function which give the same right hand side of the function above
y = 2 sin (x + [tex]\frac{3\pi }{4}[/tex] )
∵ 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) = 2[sin x cos [tex]\frac{3\pi }{4}[/tex] + cos x sin [tex]\frac{3\pi }{4}[/tex] ]
∵ sin [tex]\frac{3\pi }{4}[/tex] = [tex]\frac{\sqrt{2}}{2}[/tex] and cos [tex]\frac{3\pi }{4}[/tex] = [tex]-\frac{\sqrt{2}}{2}[/tex]
- Substitute them in the right hand side
∴ 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) = 2[ [tex]-\frac{\sqrt{2}}{2}[/tex] sin x + [tex]\frac{\sqrt{2}}{2}[/tex] cos x]
- Multiply the bracket in the right hand side by 2
∴ 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) = [tex]-\sqrt{2}[/tex] sin x + [tex]\sqrt{2}[/tex] cos x
- Switch the two terms of the right hand side
∴ 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) = [tex]\sqrt{2}[/tex] cos x - [tex]\sqrt{2}[/tex] sin x
∴ y = [tex]\sqrt{2}[/tex] cos x - [tex]\sqrt{2}[/tex] sin x
- The same with right hand side of the function above
∴ y = 2 sin (x + [tex]\frac{3\pi }{4}[/tex] ) has the same graph of y = 2 cos (x + [tex]\frac{\pi }{4}[/tex] )
Answer:
y=2sin(x+3pi/4)

A bag contains 31 red blocks, 49 green blocks, 24 yellow blocks, and 21 purple blocks. You pick one block from the bag at random. Find the indicated theoretical probability.
P(green or red)
Answer:
16/25 or 0.64 or 64%
Step-by-step explanation:
Please kindly check the attached file for explanation
Answer: The probability of picking a green block or red block is 0.64 (or 64%)
Step-by-step explanation: The total number of blocks can be derived as;
31 (R) + 49(G) + 24(Y) + 21(P) = 125
With 125 blocks in total, there are 125 possibilities and the possibility of picking any of the four colors shall be be determined as a fraction of the entire possible outcomes.
The probability of picking a green ball when picked at random is given as;
P(Green) = Number of required outcomes ÷ Number of all possible outcomes
P(Green) = 49/125
(Note that there are 49 green blocks and a total of 125 blocks of all four colors)
Also the probability of picking a red ball when picked at random is given as;
P(Red) = Number of required outcomes ÷ Number of all possible outcomes
P(Red) = 31/125
The probability of picking a green block or a red block is given as P(green or red)
P(Green or Red) = 49/125 + 31/125
P(Green or Red) = 80/125
P(Green or Red) = 16/25
P(Green or Red) = 0.64
Therefore the probability of picking a green or red block at random is 0.64 or 64%

Answer:
The correct two options are;
b. Richter Scale
c. Acidity/Alkalinity
Step-by-step explanation:
Here we have
b. The Richter Scale, given by the following relation;
[tex]M = log(\frac{I}{I_0} )[/tex]
M = Earth quake magnitude
I = Earthquake intensity
I₀ = Earthquake intensity of magnitude 0
Comparing two Earthquakes, A and B, we have
[tex]M_A - M_B = log(\frac{I_A}{I_B} )[/tex]
c. Acidity/Alkalinity are determined by the pH of the solution, which is the negative logarithm of the hydrogen ion concentration
pH = -log₁₀ [H⁺].
