Answer:
Step-by-step explanation:
(2x² - 3x + 1 )(x - 3) = (2x² - 3x + 1)*x + (2x² - 3x + 1)*(-3)
= 2x²*x - 3x*x + 1*x + 2x²*(-3) - 3x*(-3) + 1*(-3)
= 2x³ - 3x² + x - 6x² + 9x - 3
= 2x³ - 3x² - 6x² + x + 9x - 3 {Combine like terms}
= 2x³ - 9x² + 10x - 3
A box in the shape of a triangular prism is painted for a project. Which formula would be used to find the lateral surface area of the triangular prism?
Answer:
LSA = (a+b+c)×h
Step-by-step explanation:
The formula that would be used to find the lateral surface area of the triangular prism = perimeter of base(P) × Height of prism(H)
Let us assume that three side of triangle are a, b, c and height of prism is h
Then lateral surface area of the prism can be LSA = (a+b+c)×h

A sculptor is planning to make two triangular prisms out of steel. The sculptor will use ABC for the bases of one prism and DEF for the bases of the other prism.
a) is ABC similar to DEF explain
b) suppose the sculptor makes both prisms with the same height. which prism will have a greater volume? how many times greater? show your work
Answer:
a) yes, they are similar
b) ΔDEF will have a greater area
1.2 times greater (which is the same proportion as 36/30)
Step-by-step explanation:
a) 40/48 = 0.8333
30/6 = 0.8333
Same ratio so they are similar
b) ΔDEF will have a greater area because EF is longer than BC.
area of ΔABC = 1/2(30)(40) = 600 cm²
area of ΔDEF = 1/2(36)(40) = 720 cm²
720/600 = 1.2 x greater
In square units, what is the area of the blue sector in the figure above? Round to the nearest tenth.
Given:
A figure of a circle with radius 8. The central angle of the blue sector is 60 degrees.
To find:
The area of the blue sector.
Solution:
Area of a sector is:
[tex]A=\pi r^2\dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta [/tex] is the central angle of the sector in degrees.
Putting [tex]r=8, \theta=60^\circ, \pi=3.14[/tex], we get
[tex]A=(3.14)\cdot (8)^2\cdot \dfrac{60^\circ}{360^\circ}[/tex]
[tex]A=(3.14) \cdot (64)\cdot \dfrac{1}{6}[/tex]
[tex]A=33.49333....[/tex]
Approximate the value to the nearest tenth.
[tex]A\approx 33.5[/tex]
Therefore, the area of the blue sector is about 33.5 sq. units.

Pls don't show your work, just solve it.
Answer:
x > 1.5
Step-by-step explanation:
I am not sure what exactly the question asks, because there doesn't need to be an absolute value bracket, but from what we can see, x is greater than 1.5, so the equation would be

Create the equation of a quadratic polynomial, in standard form, that has zeroes of -5 and 2 and which passes through the point (3,-24).
9514 1404 393
Answer:
y = -3x^2 -9x +30
Step-by-step explanation:
When a polynomial has a zero at x=p, it has a factor of (x -p). The factors of your quadratic are ...
f(x) = (x +5)(x -2)
At the point x=3, the value of this product is ...
f(3) = (3 +5)(3 -2) = (8)(1) = 8
In order for that value to be -24, it needs to be multiplied by a scale factor of -3. The quadratic you want is ...
y = -3(x +5)(x -2)
y = -3x^2 -9x +30 . . . . . standard form

x+23 = 35
5x = 60
Step-by-step explanation:
Answer:
12. 18
14. x = 12; x + 23 = 35; 5x = 60
Step-by-step explanation:
12.
100 = ? + 82
? = 18
14.
x + 23 + 5x + 85 = 180
6x + 108 = 180
6x = 72
x = 12
x + 23 = 12 + 23 = 35
5x = 5 * 12 = 60

Boats A, B, C, and D are all the same distance from Boat O.
Answer:
α = 62°
β = 56°
gamma = 90°
Step-by-step explanation:
ΔAOB is isosceles, so m∠A = m∠ABO = 28
28 + 28 + m∠AOB = 180
m∠AOB = 180 - 28 - 28 = 124
β = 180 - 124 = 56
arcAB = 124
ΔBOC is isosceles. α = m∠BCO = 1/2(arc AB) = 1/2(124) = 62
∠D is inscribed in a semicircle
m∠D = gamma = 90°
You start at (9, 5). You move right 1 unit. Where do you end? y x 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 0 ( , )
Answer:
(10, 5)
Step-by-step explanation:
Starting coordinate : (9, 5)
x = 9 ; y = 5
Vertical distance (up and down) = y
Horizontal distance (left and right) = x
Movement to the right = positive
Movement to the left = negative
Hence, 1 unit moved to the right ; x + 1
Therefore ;
(9 + 1, 5)
= (10, 5)
square root of 119 with work
Answer:
This can't really be broken down, so you would either write the answer as the question, or put it in decimal form.
So the choices would be:
[tex]\sqrt{119}[/tex] or 10.9

and because the ________________________________. Therefore, ABCD is a parallelogram because both pairs of opposite sides are parallel.
Answer:
The answer is "lengths of opposite sides are equal "
Step-by-step explanation:
The parallelogram is a four-sided one in parallel opposites and therefore opposite angles equal. Each quadrilateral is called a rhombus with equal sides, as well as a parallelogram that also has correct angles is recognized as a rectangle. Its flat form with 4 smooth edges is parallel on the other side, so that when the opposite sides were equal in length. That's why ABCD is also a parallelogram because the two sides are parallel.
The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is L = StartRoot d squared + h squared EndRoot. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall?
Answer:
Step-by-step explanation:
The formula that relates the length of a ladder, L, that leans against a wall with distance d from the base of the wall and the height h that the ladder reaches up the wall is L = StartRoot d squared + h squared EndRoot. What height on the wall will a 15-foot ladder reach if it is placed 3.5 feet from the base of a wall?
L = √d² + h²

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle).
[tex]l=\sqrt{h^2+d^2}[/tex]
[tex]l=15[/tex] feet
[tex]d=3.5[/tex] feet
[tex]15=\sqrt{3.5^2+h^2}[/tex]
[tex]15=\sqrt{12.25+h^2}[/tex]
[tex]225=12.25+h^2[/tex]

Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3\sqrt{2} }{h}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

Answer:
BAC=15
Step-by-step explanation:
angle BOA= 180-30= 150
triangle BAO is isosceles because it has two equal sides, radii of a circumference so the angles ABO=BAO=(180-150)/2=15
In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70° angle.
Write and solve an equation to determine the measure of angle x.
Answer:
X =50 Y is also 50 since they are vertical angles
Step-by-step explanation:
70+ 60 + X = 180 (the 3 angles form a straigh line = 180 )
130 +X =180
X = 180-130
X=50
