Answer:
4Step-by-step explanation:
Let,
The third side of the triangle be = x
According to Pythagoras Theorem,
[tex] {5}^{2} - {3}^{2} = {x}^{2} [/tex]
[tex] = > {x}^{2} = 25 - 9[/tex]
[tex] = > {x}^{2} = 16[/tex]
[tex] = > x = \sqrt{16} [/tex]
=> x = 4
Hence,
third side of the triangle is 4 (Ans)

B. g(x) = 1x1 + 4
O c. g(x) = (x - 41
O D. g(x) = (x + 41
Answer:
D
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Here g(x) is the graph of f(x) shifted 4 units to the left , then
g(x) = | x + 4 | → D
The equation of function g(x) is [tex]g(x) = |x + 4|[/tex]
From the graph, we have the following highlights
The blue line represents f(x)The orange line represents g(x)Also, the blue line is shifted 4 units to the left, to get g(x)
The rule of this transformation is:
[tex](x,y) \to (x + 4,y)[/tex]
So, we have:
[tex]g(x) = |x + 4|[/tex]
Hence, the equation of function g(x) is [tex]g(x) = |x + 4|[/tex]

help please I don't know how to solve this
Answer:
x = 23 degrees
Step-by-step explanation:
It is given that the two parallel lines, (m) and (n) are intersected by a transversal. The two given angles (5x - 20) and (85) are alternate corresponding. Meaning that they are supplementary; their angle measures add up to (180) degrees. Based on this given information, form an equation and solve for the parameter (x).
(5x - 20) + (85) = 180
Simplify,
5x + 65 = 180
Inverse operations,
5x + 65 = 180
-65 -65
5x = 115

I don’t understand question 42,43
Answer:
42. x = 25
43. LM = 11
Step-by-step explanation:
For 42, the three angles of a triangle, when added, = 180 degrees. We know that one of the angles is 90 degrees...a right angle.
So: 90 + 2x + x + 15 = 180
105 + 3x = 180
3x = 75
x = 25
If they ask for more information: the three angles are 90 degrees, 50 degrees (2x), and 40 (x + 15). 90 + 50 + 40 = 180
For 43, ray PN bisects (cuts in equal halves) the triangle. We know this because the two segments LP and PM are equal. As a result, the triangles LPM and PNM are mirror images. Since MN = 11, LM also = 11.

The Maron Luggage Company claims they have a suitcase large enough to fit a 34-inch baseball bat inside. If the suitcase has height and depth 17 inches by 11 inches, what must its whole-number length be, at minimum?
Answer:
the height of the suitcase is 34 in
Step-by-step explanation:
Given that
The length of the baseball bat is 34 in
And, the height and depth of suitcase is 17 inches by 11 inches
Based on the above information
The height of the suitcase would be equivalent to the height of the baseball bat i.e. 34 in
Hence, the height of the suitcase is 34 in
The same would be considered

Um.... quick question what are the problems because the file don't work!
Step-by-step explanation:
Andy, Bob and Chuck run a gardening business. Andy pays all the annual fixed costs (insurance, telephone line rental, etc.) by installments, which amount to $400 per week. Bob buys the materials for any job they do. Chuck collects the payment for jobs. They split all profits evenly and settle down after every job is completed. They have just done a landscaping and re-fencing job for Mrs. Smith that took the three of them exactly two weeks. Materials cost $1,400 and Mrs. Smith paid Chuck $4,900. How much does Chuck owe Andy and Bob?
Answer:
$1800
He owes them $900 each
Step-by-step explanation:
Profit = Revenue - (fixed cost + material cost)
fixed cost $400 x 2 = 800
4900 - (800 + 1400) = $2,700
Since they share the profits equally, each would get 2700/3 = 900

find the interest on $6,000 at 5% for one year
Answer:
300$
I=P×r×t
P= is the principal amount, $6000.00.
r=is the interest rate, 5% per year (you have to put it in decimal form to multiply)
t= is the time involved, which is 1 year
To find interest multiply 6000 × 0.05 × 1
the points m(-10, 3) and p(-4, -8) are graphed on the coordinate plane. to the nearest tenth of a unit what is the distance between points m and p
Answer:
Distance between points m and p = 12.53 unit (Approx.)
Step-by-step explanation:
Given:
Co-ordinate of points
m(-10, 3)
p(-4, -8)
Find:
Distance between points m and p
Computation:
Distance between two points = √(x1 - x2)² + (y1 - y2)²
Distance between points m and p = √(-10 + 4)² + (3 + 8)²
Distance between points m and p = √(-6)² + (11)²
Distance between points m and p = √36 + 121
Distance between points m and p = √157
Distance between points m and p = 12.53 unit (Approx.)
A triangle has sides with lengths of 8 millimeters, 15 millimeters, and 17 millimeters. Is it a right triangle?
Answer:
yes.
Step-by-step explanation:
to find this answer, use the pythagoras theorem. the pythagoras theorem states that a² + b² = c².
to see if this is a right angled triangle, we will use this formula, as the pythagoras theorem only works for right angled triangles.
we are going to work out c, which is always the hypotenuse. the hypotenuse is the longest side of a triangle, that is larger than the other values. we know that the hypotenuse of this triangle is 17, so let’s see if that’s the answer we get.
calculation:
a² + b² = c²
a = 8 millimetres
b = 15 millilitres
c = ?
8² + 15² = c²
64 + 225 = c²
64 + 225 = 289.
289 = c²
√289 = c
√289 = 17.
the pythagoras theorem correctly identified the length of the hypothenuse. as i said earlier, this theorem only works on right angled triangles, therefore, this triangle is right angled.
The cone and cylinder above have the same radius and height. The volume of the cone is 210 cubic centimeters. What is the
volume of the cylinder?
Answer:
706.3 cm³
Step-by-step explanation:
Given
"The cone and cylinder above have the same radius and height..."
the volume of the cone = 210 cubic centimeters
Formula
The formula for the volume of a cylinder is V=Bh or V=πr2h. The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h.
How to solve
Given radius and height calculate the volume, lateral surface area, and total surface area.
Calculate V, L, A | Given r, h
use the formulas above
Given radius and volume calculate the height, lateral surface area, and total surface area.
Calculate h, L, A | Given r, V
h = V / πr2
Given radius and lateral surface area calculate the height, volume, and total surface area.
Calculate h, V, A | Given r, L
h = L/2πr
Given the height and lateral surface area calculate the radius, volume, and total surface area.
Calculate r, V, A | Given h, L
r = L/2πh
Given height and volume calculate the radius, lateral surface area, and total surface area.
Calculate r, L, A | Given h, V
$r = √( V / πh )

Answer:
1. 53
2. 20
3. 37
4. 29
Step-by-step explanation:
Since your trying to find the hypotenuse you equation is...
1. 28^2 + 45^2 = C^2
784 + 2025 = C^2
Square Root 2809= C^2
C=53
So after you square root 2809 you get 53.
2. 12^2 + 16^2 = C^2
144 + 256 = C^2
Square Root 400 = C^2
C=20
So after you square root 400 you get 40.
3. 12^2 + 35^2 = C^2
144 + 1225 = C^2
Square Root 1369 = C^2
C=37
So after you square root 1359 you get 37.
4. 20^2 + 21^2 = C^2
400 + 441 = C^2
Square root 841 = C^2
C=20
So after you square root 841 you get 29.
