Answer:
3x³ - 10x² + 3x + 10
Step-by-step explanation:
multiply 'x' by each term in the second expression:
(x-2)(3x²-4x-5) = 3x³ -4x² - 5x
now multiply '-2' by each term in the second expression:
-6x² + 8x + 10
combine 'like' terms: -4x² + (-6x²) to get -10x²
combine 'like' terms: 8x - 5x = 3x
answer: 3x³ - 10x² + 3x + 10
help w this questionn ^^
Answer:
BC = 8 cm
Step-by-step explanation:
tan(x) = sin(x)/cos(x)
sin(x) is the opposite side of the angle x.
cos(x) is the side with a right angle to sin(x).
2 = 12/EC
EC = 12/2 = 6 cm
=>
CD = ED - EC = 10 - 6 = 4 cm
now, the same tan(x) relation had to be true for BCD.
tan(x) = BC/CD
2 = BC/4
BC = 8 cm
What should be the first step in adding these equations to eliminate y?
Answer:
D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Since you want to eliminate y, the y value on the bottom equation has the be the opposite of the y value on the top one. So it's 4y on the top one, so the bottom one has to be -4y to eliminate y. The bottom one is -2y, so -2 times 2 =-4, so multiply the bottom one by 2 omg i miss linear combination

Answers:
a = 1/3
b = -6
c = 7
======================================================
Explanation:
The terms of the given expression rearrange to [tex]\frac{1}{3}x^2 - 6x+7[/tex] which is now in standard form (the exponents decrease when moving from left to right).
We can see that
a = 1/3
b = -6
c = 7
after matching that with the ax^2+bx+c form.

A bus is traveling between two cities that
are in neighboring states. The graph of
the function d(t) = 60|t − 1.25| shows the
distance of the bus in miles from the state line,
where t represents time in hours.
a. What does the graph tell you about the bus ride?
b. What is the average rate of change from 1.5 h to 2 h? What does the
average rate of change represent?
Answer:
(a). The bus decelerated to rest through 75 miles for 1.25 hours and accelerated through same distance for 1.25 hours.
b.
[tex]s _{1} = \frac{d _{1} }{t _{1} } \\ = \frac{15}{1.5} \\ s _{1} = 10 \: miles \: per \: hour \\ \\ s _{2} = \frac{d _{2} }{t _{2}} = \frac{45}{2} \\ = 22.5 \: miles \: per \: hour \\ average = \frac{22.5 + 10}{2} \\ = 16.25 \: miles \: per \: hour[/tex]
a) The bus decelerated to rest through 75 miles for 1.25 hours and accelerated through same distance for 1.25 hours.
b)The average rate of change represent is 16.25 miles per hour.
What is a function rule? A functional rule is the relationship between an input or domain and an output or scope.A relation is a function only if it has a value within each domain value.Functions are written like where is the input value. The general form of the function is:A vertical test is run graphically to determine if the relationship is a function.A formula, rule, or law that defines the relationship between one variable (the independent variable) and another (the dependent variable).Functions are ubiquitous in mathematics and essential in the natural sciences for formulating physical relationships.A formula, rule, or law that defines the relationship between one variable (the independent variable) and another (the dependent variable).a) The bus decelerated to rest through 75 miles for 1.25 hours and accelerated through same distance for 1.25 hours.
b)
s1 = d1/t1
15/1.5
s1 = 10 miles per hour
s2 = d2/t2
22.5 miles per hour
Average = 16.25 miles per hour.

The given lengths are two sides of a right triangle. All three side lengths of the triangle are integers, and together they form a Pythagorean triple. Find the length of the third side, then indicate whether it is a leg or a hypotenuse.
Answer:
C) 92, leg
Step-by-step explanation:
a² + 28² = 96² *the hypotenuse is always the longest side
a² + 784 = 9216
a² = 8432
a = √8432
'a' is approximately 92, and is a leg

Answer:
The probability is 2/5
Step-by-step explanation:
There are 25 sections on the board
And 10 of those squares are coloured yellow
Therefore;

If m and n are two natural number and m^n =8,then n^mn is.
Answer:
729
Step-by-step explanation:
M has to be 2 and n has to be 3, because 2^3 = 8
if it was 3^2 it would be 9
2^3 = 8
3^(2*3) = 3^6 = 729

Answer:
1583.4 ft³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
The radius is half the diameter, so is (12 ft)/2 = 6 ft. Then the volume is ...
V = π(6 ft)²(14 ft) ≈ 1583.4 ft³
_____
Additional comment
The number shown in the problem statement answer box is the number you would get using the diameter in the above formula instead of the radius.
The volume of cylinder is 1583.4ft³.
Step-by-step explanation:
Given that :-
Height of cylinder = 14 ftBase diameter if cylinder = 12 ft
so, Radius of cylinder, r = 12 / 2 = 6 ftTo find :-
Volume of cylinderSolution :-
Using formula
Volume of cylinder = π × r² × h
Substitute the value
Volume of cylinder = π × (6ft)² × 14 ft
evaluate the exponent
Volume of cylinder = π × 36 ft ² × 14ft
multiply
Volume of cylinder = π × 504 ft³
Using , π = 3.14
Volume of cylinder = 3.14 × 504 ft³
Hence, the volume of cylinder is 1582.56ft³.
Round nearest tenth place = 1583.4 ft³.

Teresa tiene 12 años , su hermano pere tiene 7 y su padre 44. QUANTOS AÑOS TIENE Q PASAR PARA Q LA SUMA DE LAS EDADES DE TERESA Y SPERE SEAN IGUALES
Answer:
Tienen que pasar 25 años para que la suma de las edades de Teresa y Pere sean iguales a la edad de su padre.
Step-by-step explanation:
Dado que Teresa tiene 12 años, su hermano Pere tiene 7 y su padre 44, para determinar cuántos años tienen que pasar para que la suma de las edades de Teresa y Pere sean iguales a la edad de su padre se debe realizar el siguiente cálculo:
12 + 7 = 19
44 - 19 = 25
44 + 25 = 69
(12 + 25) + (7 + 25) = 37 + 32 = 69
Por lo tanto, tienen que pasar 25 años para que la suma de las edades de Teresa y Pere sean iguales a la edad de su padre.

In a triangular prism area of rectangular surface is twice the area of traingular surface if tsa 3000. Find the area of triangular surface
Answer:
375
Step-by-step explanation:
Applying,
Total surface area of the triangular prism = 3×Area of the rectangular surface + 2×area of the triangular surface
Assuming the triangular base is an equilateral triangle
A = 3A'+2B.................... Equation 1
Where A = Total surface area of the prism, A' = Area of the rectangular surface, B = Area of the triangular base.
From the question,
IF A' = 2B,
Given: A = 3000
Substitute these values into equation 1
3000 = 3(2B)+2B
3000 = 6B+2B
3000 = 8B
8B = 3000
B = 3000/8
B = 375
