Answer:
f(10)=290
Step-by-step explanation:
Function Evaluation
Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.
We are given the function:
[tex]f(x)=3x^2-x[/tex]
It's required to find f(10). We replace the x for 10:
[tex]f(10)=3*10^2-10[/tex]
Operating:
[tex]f(10)=3*100-10[/tex]
[tex]f(10)=300-10[/tex]
[tex]f(10)=290[/tex]
Thus, f(10)=290

The measure of the angle ∠NPQ will be 118°. Then the correct option is C.
What is a trapezoid?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
In the isosceles trapezoid, the sum of the opposite angle is 180 degrees. Then the equation is given as,
∠NMQ + ∠NPQ = 180°
∠NPQ + 32° + 30° = 180°
∠NPQ = 118°
The measure of the angle ∠NPQ will be 118°. Then the correct option is C.

1/3 x + 1 = 5/6 x - 3
Answer:
x=8
Step-by-step explanation:
Step 1: Subtract 5/6x from both sides.
1/3x+1−5/6x=5/6x−3−5/6x
−1/2x+1=−3
Step 2: Subtract 1 from both sides.
−1/2x+1−1=−3−1
−1/2x=−4
Step 3: Multiply both sides by 2/(-1).
(2/−1)*(−1/2x)=(2/−1)*(−4)
x=8

18w2(squared) - w - 39
Answer:
w = 1.5 and -1.44
Step-by-step explanation:
Given the quadratic equation 18w^2 - w - 39
Using the general formuls
w = 1 ±√1²-4(18)(-39)/2(18)
w =1 ±√1+2808/36
w =1 ±√2809/36
w = 1+53/36 and 1-53/36
w = 54/36 and -52/36
w = 1.5 and -1.44

What is the y-intercept of the line that passes through the points (2,-1) and (-3,9)
Answer:
The equation of the straight line y = -2x +3
y-intercept = 3 and m =-2
Step-by-step explanation:
Step(i):-
Given that the points are ( 2,-1) and (-3,9)
The slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{9-(-1)}{-3-(2)} = \frac{10}{-5} = -2[/tex]
Step(ii):-
The equation of the straight line passing through the point ( 2,-1) and slope m=-2
y-y₁ = m( x- x₁)
y -(-1) = -2 ( x-2)
y +1 = -2x +4
2x +y +1-4 =0
2x +y -3 =0
Final answer:-
The equation of the straight line y = -2x +3
