Area of a right angled triangle = 1/2 * b * h
Step-by-step explanation:
For a right- angled triangle; the sum of squares of the opposite and adjacent sides = square of the longest side ( i.e. hypothenuse )
hence the Area of a right angled triangle = 1/2 * b * h
where : b = adjacent , h = opposite side
The original price of a computer was reduced by 225 dollars. The new discounter price is 1274 dollars.
Answer:
1499
Step-by-step explanation:
Given that :
New discounted price = 1274
Let original price = p
Reduction in original price = 225
Original price is the sum of the reduction and the new discounted price
The Original price = Reduction in original price + new discounted price
P = 225 + 1274
P = 1499

(0, 0), (0, 6), (6, 0)
(3, 3), (0, 9), (9, 0)
(0, 0), (0, 9), (9, 0)
Answer:
(0,0), (0,9), (9,0)
Step-by-step explanation:
The matrix corresponding vertices are:
(0,0)
(0,3)
(3,0)
Rosa scales by 3T, so we need to multiply each point by 3.
(3*0, 3*0)
(0*3, 3*3)
(3*3, 0*3)
=
(0,0)
(0,9)
(9,0)
last answer choice is right.
pls mark me brainly
The vertices of the scaled triangle, 3T is, (0, 0), (0, 9), (9, 0).
What is a scale factor?The scale factor defines a variable in a ratio of two different measurements.
Sometimes drawings of large models are represented in a scale factor of a smaller unit.
Given, A matrix [tex]T=\begin{bmatrix}0 & 0 & 3\\0 & 3 & 0\end{bmatrix}[/tex] represents the vertices of a triangle.
Let, ABC be the triangle,
So, A(0, 0), B(0, 3), C(3, 0).
Now, If [tex]T=\begin{bmatrix}0 & 0 & 3\\0 & 3 & 0\end{bmatrix}[/tex], Then [tex]3T=3\begin{bmatrix}0 & 0 & 3\\0 & 3 & 0\end{bmatrix}[/tex].
Therefore, [tex]3T=\begin{bmatrix}0 & 0 & 9\\0 & 9 & 0\end{bmatrix}[/tex].
Hence, The new vertices are, (0, 0), (0, 9), (9, 0).

Elizabeth ships a gift through the mail. The gift weighs 8 pounds 11 ounces. She packs the gift in a shipping box with bubble wrap. The package weighs 12 pounds 4 ounces. How much does the shipping box and bubble wrap weigh?
Answer:
3lbs 9 ounces
Step-by-step explanation:
16 ounces in a pound
9514 1404 393
Answer:
3 lb 9 oz
Step-by-step explanation:
Sometimes, addition is easier than subtraction when it comes to finding the difference.
There are 16 ounces in a pound.
8 lb 11 oz + 5 oz = 9 lb
9 lb + 3 lb 4 oz = 12 lb 4 oz
To get from 8 lb 11 oz to 12 lb 4 oz, we have added ...
5 oz + 3 lb 4 oz
= 3 lb 9 oz . . . . weight of packing materials
__
Or, you can do the subtraction in the usual way.
total weight = gift weight + packing weight
packing weight = total weight - gift weight
= (12 lb 4 oz) - (8 lb 11 oz)
= (12 lb -8 lb) + (4 oz -11 oz)
= 4 lb - 7 oz
packing weight = 3 lb 9 oz

if you horizontally shift the square root parent function f(x)=√x left two units what is the equation of the new function
Answer:
[tex] \sqrt{x + 2} [/tex]
If you horizontally shift the square root parent function f(x)=√x left two units the equation of the new function is: g(x) = √(x + 2).
What is horizontal shift?A horizontal shift is a function transformation that shifts a graph to the left or right without changing its shape.
If we want to shift the square root parent function f(x) = √x two units to the left, we must replace the argument x with (x + 2), because a positive value of x + 2 gives us the same x value two units to the left.
So the equation of the new function is:
g(x) = √(x + 2)
This new function is the square root function shifted two units to the left. For any given input value of x, we add 2 to it before taking the square root. This causes the graph to shift horizontally to the left by two units.
Thus, g(x) = √(x + 2) will be the new function.

Problem 2 : Using in the pattern in the image below, how many dots would be in Step 4
Answer:
20
Step-by-step explanation:
One pattern is that we are adding one row and one column for each step.
The first step has 1 row and 2 columns,
the second one has 2 rows and 3 columns,
and the third has 3 rows and 4 columns.
Thus, it would make sense for the fourth step to have 4 rows and 5 columns. This makes a rectangle with a length and a width, with the area of the rectangle being length * width. 4 * 5 = 20 as our number of dots

Answer:
$375.32
Step-by-step explanation:
100% - 40% = 80%
80/100 = 0.8 (multiplier)
521.28 x 0.8 = 417.024
417.024 to 417.02 (2 d.p.)
100 - 10 = (ans)/100 = 0.9
417.02 x 0.9 = 375.318
$375.32
Step 1: Find the sales price
The surfboard was marked down 40% of its original price, $521.28.
0.40(521.28) = 208.512
521.28 - 208.512 = 312.768
Step 2: Find the final price
We add the tax on the sales price, not the original price. The tax is 10% in this case.
0.10(312.768) = 31.2768
312.768 + 31.2768 = 344.0448
Final price = $344.04
---I did not round until the end in this case, but rounding at every step leads to an answer of $344.05

The position vector of p (relative to the origin) is op = (x, y). if the magnitude of op is 5 units, find the set of all possible values of (x, y), with x, y E z
Answer:
S = {(0, 5), (0, - 5), (3, 4), (3, -4), (-3, 4), (-3, -4), (4, 3), (4, -3), (-4, 3), (-4, -3), (5,0), (-5, 0) }
Step-by-step explanation:
Remember that the distance between two points (a, b) and (c, d) is given by:
[tex]distance = \sqrt{(a - c)^2 + (b - d)^2}[/tex]
So, here we have that the distance between the point (x, y) and the origin, (0, 0) must have a magnitude of 5 units, then we want to solve:
[tex]5 = \sqrt{(x - 0)^2 + (y - 0)^2} \\5 = \sqrt{x^2 + y^2}[/tex]
If we square both sides, we get
[tex]5^2 = (\sqrt{x^2 + y^2} )^2\\25 = x^2 + y^2[/tex]
Now we want to find all the points (x, y) that meet this condition, suc that:
x ∈ Z
y ∈ Z
So both x and y must be integers.
So here we can just play with different values of x and y.
For example, if we define:
x = 0 we get:
25 = 0^2 + y^2
25 = y^2
√25 = y
Then we can have y = 5 or y = -5
from this we got two points:
(0, 5) and (0, - 5)
if x = 1 we have:
25 = 1^2 + y^2
25 - 1 = y^2
24 = y^2
There is no integer such that its square is equal to 24, so we can stop here.
if x = 2 or - 2, we have:
25 = 2^2 + y^2
25 = 4 + y^2
25 -4 = 21 = y^2
Again, there is no integer such that its square is equal to 21, so we can stop here.
if x = +3 or -3, we have:
25 = 3^2 + y^2
25 = 9 + y^2
25 - 9 = 16 = y^2
√16 = y
then we can have y = 4 or y = -4
from this we got four points:
(3, 4)
(-3, 4)
(3, -4)
(-3, -4)
And for symmetry, if x = 4 or -4 we have the points:
(-4, 3)
(4, 3)
(-4, -3)
(4, -3)
finally, again for symmetry, if we take x = 5 or x = -5 we have the points:
(5,0)
(-5, 0)
Concluding, the set of all possible values (x, y) is:
S = {(0, 5), (0, - 5), (3, 4), (3, -4), (-3, 4), (-3, -4), (4, 3), (4, -3), (-4, 3), (-4, -3), (5,0), (-5, 0) }

I. Tell whether each statement is TRUE or FALSE. Refer to the figure below. Write your answer on the space provided.
Answer:
1. TRUE
2. TRUE
3. TRUE
4. TRUE
5. FALSE
6. TRUE
Step-by-step explanation:
1. From the diagram, we have that m∠2 and m∠7 are alternate interior angles
If m∠2 = 70° and m∠7 = 70°, then we have;
m∠2 = 70° = m∠7
m∠2 = m∠7
Therefore, the alternate interior angles of the lines l₁, and l₂ are equal, and therefore, the lines l₁ and l₂ are parallel, l₁ ║ l₂
TRUE
2. If m∠3 = 90° and m∠7 = 90°, therefore, the angle formed by the intersection of l₃ and l₂ = 90°
Therefore l₃ ⊥ l₂
TRUE
3. m∠5 and m∠7 are corresponding angles
If m∠5 = 85° and m∠7 = 85°, then, m∠5 = m∠7
Therefore, the corresponding angles formed by the lines l₁ and l₂ are equal, therefore;
l₁ ║ l₂
TRUE
4. Whereby we have, m∠1 = m∠5, we get;
m∠1 + m∠5 = 180° by sum of angles on a straight line
∴ m∠1 + m∠5 = m∠1 + m∠1 = 2·m∠1 = 180°
m∠1 = 180°/2 = 90°
∴ m∠1 = 90° = m∠5, and l₃ ⊥ l₁
TRUE
5. m∠1 and m∠8 are alternate exterior angles
If m∠1 = 98° and m∠8 = 82°
∴ m∠1 ≠ m∠8 and l₁ ∦ l₈
FALSE
6. Given that l₁║ l₂, then the angle formed between l₁ and l₃ will be equal to th angle formed between l₂ and l₃
Therefore;
If l₁║ l₂, and l₃ ⊥ l₁, then l₃ ⊥ l₂
(If l₁║ l₂, and l₃ is perpendicular to l₁, then l₃ is also perpendicular to l₂)
TRUE

Given:
y is directly proportional to x.
[tex]y=30[/tex] when [tex]x=5[/tex]
To find:
The equation that connects y with x.
Solution:
It is given that, y is directly proportional to x. So,
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
We have, [tex]y=30[/tex] when [tex]x=5[/tex]. Substituting these values in (i), we get
[tex]30=k(5)[/tex]
Divide both sides by 5.
[tex]\dfrac{30}{5}=k[/tex]
[tex]6=k[/tex]
Substituting [tex]k=6[/tex] in (i), we get
[tex]y=6x[/tex]
Therefore, the required equation is [tex]y=6x[/tex].
