Lee's family had a garden in the shape of a right triangle. The total area of the garden is 16 square feet. If they expand
the garden to form a triangle with twice the base
and twice the height, by how much will they increase the size of their
garden?
O 16 square feet
• 32 square feet
O
48 square feet
64 square
feet
Answer:
48 square feet
Step-by-step explanation:
Given
Before expansion
[tex]A_1 = \frac{1}{2}bh[/tex] --- area of a triangle
[tex]A_1 = 16ft^2[/tex] --- value of the area
After the base and height were expanded, the area becomes:
[tex]A_2 = \frac{1}{2}BH[/tex]
Where
[tex]B = 2b[/tex]
[tex]H = 2h[/tex]
Substitute 2b for B and 2h for H in [tex]A_2 = \frac{1}{2}BH[/tex]
[tex]A_2 = \frac{1}{2} * 2b * 2h[/tex]
[tex]A_2 = \frac{1}{2} * 2*2*b*h[/tex]
[tex]A_2 = \frac{1}{2} * 4*b*h[/tex]
Rewrite as:
[tex]A_2 = 4 * \frac{1}{2} *b*h[/tex]
[tex]A_2 = 4 * \frac{1}{2}bh[/tex]
Recall that: [tex]A_1 = \frac{1}{2}bh[/tex]
So, we have:
[tex]A_2 = 4 * A_1[/tex]
Substitute 16 for [tex]A_1[/tex]
[tex]A_2 = 4 * 16[/tex]
[tex]A_2 = 64[/tex]
So, the area is [tex]64ft^2[/tex] after the dimensions were expanded
The area increased by:
[tex]Increment = A_2 - A_1[/tex]
[tex]Increment = 64 - 16[/tex]
[tex]Increment = 48[/tex]
It increased by [tex]48ft^2[/tex]

which polynomial represents the difference below? (8x^2+9)-(6x^2+2x+2)
Answer:
The polynomial is 2 x² - 2x + 7
Step-by-step explanation:
Given polynomial
(8 x² + 9 ) - (6x² +2x +2)
= 8 x² +9 - 6x² - 2x -2
= 8x² - 6x² - 2x + 9-2
= 2 x² - 2x + 7
The polynomial is 2 x² - 2x + 7
x² - 121

I WILL MARK YOU BRILL
Answer:
Median is 3
Mean is 2.8
Im 95% sure this is correct, though if you want to double check
To find the median you would line all the numbers in order from least to greatest, then usually I would draw lines connecting the first to the last until each is paired, if it is a single digit left over then it the median is that digit, it its two left then you add them together and divide by two for the median.
For the mean add all the numbers together and divide by the total number of numbers.
Step-by-step explanation: In your problem, we're finding the mean and median. Let's do it step-by-step.
1. To find the Median, we arrange the data in an ascending order and it's middle value. If the numbers of values is an even number (2, 4, 6, 8, 10), the median will be the average of the 2 middle numbers.
Therefore, the Median is 3.
2. The Mean is the set of numbers of the sum divided by the number of terms.
Therefore, the Mean is 2.8.

Answer:
We conclude that:
cosecant (U) = 13/12Step-by-step explanation:
Given the right-angled triangle ΔUWV, it is clear that
The opposite of angle ∠U = 24The hypotenuse = 26Using the trigonometric ratio, we know that
sin Ф = opposite / hypotenuse
cosecant Ф = 1/ sin Ф
Thus,
cosecant Ф = hypotenuse / opposite
substituting Ф = U, hypotenuse = 26 and opposite = 24
cosecant (U) = 26 / 24
cosecant (U) = 13/12
Therefore, we conclude that:
cosecant (U) = 13/12Please help :D

The dot plot below shows the number of fish caught by each person on a drift boat. Which statement correctly describes the center value of the data?
The center is 3.5 because it is the value in the middle of the recorded values. The center is between 4 and 5 because those are the middle values on the scale. The center is 5 because it is the difference between the highest value and lowest value. The center is 4 because 4 is the value in the middle when all of the values are ordered from least to greatest.
Answer:
The center is 4 because 4 is the value in the middle when all of the values are ordered from least to greatest.
Step-by-step explanation:
The center point lies in the middle of the data. This is the point where the midpoint of data set is located. In the given dot plot the data is in descending order and when the data is observed the middle value is 4. The middle value can be between 4 and 5 in case if the data set was observed according to class preference and frequency would have been given separately.

With the knowledge that m∠1 = 81°, let's use these relationships to find the rest of the angles:
1 and 3 are vertical: their angle measures are the same, so m∠3 = 81°1 and 4 are corresponding: their angle measures are also the same, so m∠4 = 81°Finally, 1 and 2 are supplemental: their angle measures add up to 180°, so 81 + m∠2 = 180, making m∠2 = 99°

Polygon LMNPQ is shown on the coordinate grid. What is the preempted of polygon LMNPQ
The question is incomplete. Here is the complete question.
Polygon LMNPQ is shown on the coordinate grid. What is the perimeter of polygon LMNPQ?
A. [tex]2+12\sqrt{2}[/tex] units
B. [tex]7+2\sqrt{2}[/tex] units
C. [tex]10+4\sqrt{2}[/tex] units
D. [tex]12+2\sqrt{2}[/tex] units
E. [tex]12+4\sqrt{2}[/tex] units
Answer: E. [tex]12+4\sqrt{2}[/tex] units
Step-by-step explanation: Perimeter of a figure is the sum of all of its sides.
The polygon is drawn on a plane. The distance between a pair of points will give that side its measure.
Distance of two points is calculated as
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
Segment MN:
Coordinates: M (2,4) and N (5,8)
[tex]d=\sqrt{(5-2)^{2}+(8-4)^{2}}[/tex]
d = 5
Segment ML:
Coordinates: M (2,4) and L (4,2)
[tex]d=\sqrt{(2-4)^{2}+(4-2)^{2}}[/tex]
[tex]d=2\sqrt{2}[/tex]
Segment NP:
Coordinates: N (5,8) and P (8,4)
[tex]d=\sqrt{(5-8)^{2}+(8-4)^{2}}[/tex]
d = 5
Segment PQ:
Coordinates: P (8,4) and Q (6,2)
[tex]d=\sqrt{(8-6)^{2}+(4-2)^{2}}[/tex]
[tex]d=2\sqrt{2}[/tex]
Segment LQ:
Coordinates: L (4,2) and Q (6,2)
[tex]d=\sqrt{(6-4)^{2}+(2-2)^{2}}[/tex]
d = 2
Calculating perimeter (P):
P = MN + ML + NP + PQ + LQ
P = [tex]5+2\sqrt{2}+5+2\sqrt{2}+2[/tex]
P = [tex]12+4\sqrt{2}[/tex]
Perimeter of polygon LMNPQ is [tex]12+4\sqrt{2}[/tex] units

Answer:
y = 2x-7
Step-by-step explanation:
Point-slope equation for line of slope m that passes through (x₀,y₀):
y-y₀ = m(x-x₀)
y-1 = 2(x-4)
Put into slope-intercept form:
y = 2(x-4) + 1
y = 2x - 7

a metal pile is 500cm long correct to the nearest centimeter the pole is cut into rods each of length 5.8cm correct to the nearest millimeter calculate the largest rod the pole can be cut into
Answer:
86 pieces
Step-by-step explanation:
Given
[tex]Pole = 500cm[/tex]
[tex]Pieces = 5.8cm[/tex]
Required
Determine the largest number of rods
To do this, we simply divide the length of the pole by the length of each piece.
[tex]Number = \frac{Pole}{Pieces}[/tex]
[tex]Number = \frac{500cm}{5.8cm}[/tex]
[tex]Number = \frac{500}{5.8}[/tex]
[tex]Number = 86.2068965517[/tex]
Round down
[tex]Number = 86[/tex]
