Answer:
40
Step-by-step explanation:
Sum of all angles of triangle = 180°
∠W + ∠X + ∠Y = 180
10x + 17 + 2x - 9 + 3x + 7 = 180
10x + 2x +3x + 17 - 9 + 7 = 180
Combine like terms
15x + 15 = 180
15x = 180- 15
15x = 165
x = 165/15
x = 11
∠Y = 3x +7 = 3*11 + 7 = 33 + 7 = 40
Answer:
X is 11 and after substitution y is 40

Answer:
4. 11/6, 121/36
5. 5/8, 25/64
6. 4/7, 16/49
7. 14/9, 196/81
Step-by-step explanation:
The ratio of perimeters is the same as the ratio of corresponding legs:
perimeter ratio = red leg/blue leg
The area ratio is the square of that:
area ratio = (perimeter ratio)²
__
4.perimeter ratio = 11/6
area ratio = (11/6)² = 121/36
__
5.perimeter ratio = 5/8
area ratio = (5/8)² = 25/64
__
6.perimeter ratio = 4/7
area ratio = (4/7)² = 16/49
__
7.perimeter ratio = 14/9
area ratio = (14/9)² = 196/81

Answer:
The following function is f(x) = -9x 4 + 5x+3 is neither even nor odd.
Step-by-step explanation:
Because a function is said to be even if f (-x) = f (x). Then a function is said to be odd if f (-x) = -f (x). And there is your answer to those who need help with their math.
A ship has an island directly in the path of the destination port, so it has to travel 11.5 miles west and then 8.4 miles north to get to the port. To the nearest tenth,how much shorter would the trip be if the ship could go directly to port?
Answer:
Step-by-step explanation:
The direct distance there (without the island in the way) is found using the Pythagorean Theorem
c^2 = a^2 + b^2
a = 8.4
b = 11.5
c = ?
c^2 = 8.4^2 + 11.5^2 Square the length of the legs.
c^2 = 70.56 + 132.25 Combine
c^2 = 202.81 Take the square root.
c = 14.24
But the island is there. The distance travelled = 8.4 + 11.5 = 19.9 miles
So the additional distance = 19.9 - 14.24 = 5.66 miles.

[tex] \frac{2(3 - x)^{ \frac{5}{2} } }{5} - \frac{2(3 - x)^{ \frac{3}{2} } }{3} + C[/tex]is the answer
Step-by-step explanation:-
Given:
[tex]{\int {(x-2)\sqrt{3-x}} \ dx }[/tex]
Differentiate on both sides,
[tex]{\int {(x-2)\sqrt{3-x}} \ dx },u = 3 - x[/tex]
Isolate and substitute back,
[tex]{\int {(x-2)\sqrt{3-x}} \ \times ( - 1) du },u = 3 - x[/tex]
Substitute back,
[tex]{\int ( - ( - u + 3 - 2) \sqrt{u})du }[/tex]
Applying property of integral ∫ kf(x)dx = k ∫ f(x)dxdx,
[tex] - ∫ ( - u + 3 - 2) \sqrt{u} \: du,u = 3 - x[/tex]
Combining like terms,
[tex]- ∫ ( - u +1) \sqrt{u} \: du,u = 3 - x[/tex]
Now applying distributive property,
[tex]- ∫ (( - u +1) \sqrt{u}) \: du,u = 3 - x[/tex]
[tex] = > - ∫ ( - \sqrt{u} \times u + \sqrt{u} )\: du,u = 3 - x[/tex]
Converting to exponential form,
[tex]- ∫ ( - u^{ \frac{1}{2} } \times u + u^{ \frac{1}{2} } )\: du,u = 3 - x[/tex]
Multiplying the first two monomuals after integral, we get,
[tex]- ∫ ( - u^{ \frac{3}{2} } + u^{ \frac{1}{2} } )\: du,u = 3 - x[/tex]
Now applying the prperty of ∫ f(x) + g(x)dx = ∫ f(x)dx + ∫ g(x)dx,
[tex] - ( - ∫u^{ \frac{3}{2} } \: du + ∫u^{ \frac{1}{2} } \: du),u = 3 - x[/tex]
Now integrate the power rule,
[tex] - ( - \frac{u^{ \frac{5}{2} }}{ \frac{5}{2} } + \frac{u^{ \frac{3}{2} }}{ \frac{3}{2} } ),u = 3 - x[/tex]
Divide the fractions by multiplying its reciprocals,
[tex] - ( - u^{ \frac{5}{2} } \times \frac{2}{5} + u^{ \frac{3}{2} } \times \frac{2}{3}),u = 3 - x[/tex]
Now write as single fractions,
[tex] - ( - \frac{2u^{ \frac{5}{2} } }{5} + \frac{2u^{ \frac{3}{2} } }{3})[/tex]
Removing the parentheses,
[tex] \frac{2u^{ \frac{5}{2} } }{5} - \frac{2u^{ \frac{3}{2} } }{3},u = 3 - x[/tex]
Substitute back,
[tex] \frac{2(3 - x)^{ \frac{5}{2} } }{5} - \frac{2(3 - x)^{ \frac{3}{2} } }{3} [/tex]
Now adding the constant of integration C∈R,
[tex] \frac{2(3 - x)^{ \frac{5}{2} } }{5} - \frac{2(3 - x)^{ \frac{3}{2} } }{3} + C[/tex]
Hence, the answer.
x - 18 = 20 one step equations
Answer: the answer is x=38
Step-by-step explanation:
X-18=20 we see that 18 is being SUBTRACTED from the x which means we have to do the opposite of subtraction is addition so 20+18=38
To check: you can plug 38 for x and subtract it from 18
Demonstration: 38-18=20
X = 38
Step-by-step explanation:
X-18 = 20
we move the constants (numbers) to one side and keep the variable, unknown on the other side
X= 20+18 (we change the sign whenever we move something to the opposite side)
x= 38

Please help! What’s the answer for this?
Answer:
the answer for 1 1/3 is O 4/3
5 2/5 is T 28/5
2 4/5 is D 14/5
Step-by-step explanation:
All you have to do is multiply the whole number by the denominator and then add the numerator and the denominator stays the same.
Like on the second one you would multiply the 5 by the denominator which is also five then add the numerator,1, and that gives you the top number and the bottom one stays the same.

What is the product of the complex numbers (-3i+4) and (3i+4)?
Answer: 25
Step-by-step explanation:
Finding the product of complex numbers is not different to finding the product of real numbers
(-3i+4) * (3i+4) = -9i^2 + 12i - 12i + 16 = 25
Answer:
25
Step-by-step explanation:
An easy way to multiply binomials is the FOIL(first, outer, inner, last) method. Multiply the first terms of each binomial, -3i×3i=-9i^2. Then do the outer terms, -3i×4=-12i. Then do the inner terms 4×3i=12i. Then do the last terms, 4×4=16. Lastly combine like terms, the -12i and 12 cancel out, and you're left with -9i^2+16. i^2=1, so then you get -9(-1)+16. -9×-1=9. 9+16=25
Find the slope of the graph
Answer:
Step-by-step explanation:
m=26 when u as u go as down as {{6-2} -13
Answer:
2
Step-by-step explanation:
By definition, the slope or gradient of a line describes its steepness, incline, or grade.
m = y2 - y1 / x2 - x1
Where
m — slope
If the 2 Points are Known:
Slope (m) = ΔY/ΔX
= 7-(-1) / 3-(-1)
= 8/4
= 2/1
= 2
θ = arctan (ΔY/ΔX)
= tan¯¹(8/4)
= 63.434948822922°
ΔX = 3 – (-1) = 4
ΔY = 7 – (-1) = 8
Distance (d) = √ΔX2 + ΔY2 = √80
= 8.9442719099992

Find the mean, median, and mode of 45, 52, 17, 63, 57, 42, 54, 58
Answer:
Step-by-step explanation:
to find the mean is another way of saying to find the average. To do this we add all the listed values(45,52,17,63,57,42,54,58) then divide them by how many values we are given which in this case is 7. so the mean would be 49. now to find the median we must first put the values in numeric order(17,42,45,52,54,57,58,63) then see the number in the middle or in cases or even number of values we find the two values in the middle of the set then we add them together and divide by two. which would be 53. now to find the mode we simply find the most reoccurring number in the set and seeing as there are no repeated values in this set there is no mode.
A balloon containing 0. 500 mol Ar at 0. 00°C and 65. 0 kPa pressure is expanded by adding more argon. Formula: PV = nRT (R = 8. 317 L•kPa/mol•K) What is the original volume of the gas? L.
Using an ideal gas equation to solve the problem. Then the original volume is 17.67 liters.
What is an ideal gas equation?An ideal gas is a theoretical composed of a set of randomly moving gas particles that interact only through elastic collision.
Given
A balloon containing 0.500 mol at 0. 00°C and 65.0 kPa pressure are expanded by adding more argon.
Pressure (P) = 65 kPa
Mole (n) = 0.5 mol
Temperature (T) = 0 °C = 273.15 K
Universal gas constant (R) = 8.317 L.kPa/mol.K
We know the ideal gas equation
[tex]\rm PV =nRT\\\\V \ \ = \dfrac{nRT}{P}[/tex]
Put the values, we have
[tex]\rm V = \dfrac{0.5*8.317*273.15}{65}\\\\V = 17.67[/tex]
Thus, the original volume is 17.67 liters.

Answer:
115.5
Step-by-step explanation:
comparing side lengths of 49 and 28:
49 ÷ 28 = 1.75, so to get from 28 to 49 multiply by 1.75
this is the same thing for side lengths 38.5 and 22 as
22 × 1.75 = 38.5
the scale factor of the first triangle (GHI) to the second triangle (JKL) is 1.75 which means multiply each side of the first triangle by 1.75
so to work out x:
16 × 1.75 = 28
perimeter of JKL (second triangle) - add up lengths of the sides:
28 + 38.5 + 49 = 115.5

Answer:
6 cm²
Step-by-step explanation:
The shorter sides are base and height.
3 x 4 / 2
= 6
We have: a² + b² = 3² + 4² = 9 + 16 = 25 = 5² = c²
=> triangle ABC is a square triangle
