Answer:

Step-by-step explanation:

f(x) = (4x-5)(3x²-x+3) - 2

= (12x³-4x²+12x)-(15x²-5x+15) -2

= 12x³ - 19x² + 17x - 17

Answer:

15^3−31^2+20−4

Step-by-step explanation:

Distribute

(3−2)(5^2−7+2)

3(5^2−7+2)−2(5^2−7+2)

Distribute

3(52−7+2)−2(5^2−7+2)

15^3−21^2+6−2(5^2−7x+2)

Distribute

15^3−21^2+6−2(5^2−7+2)

15^3−21^2+6−10^2+14−4

Combine like terms

15^3−21^2+6−10^2+14−4

15^3−31^2+6+14−4

Combine like terms

15^3−31^2+6+14−4

15^3−31^2+20−4

Solution

15^3−31^2+20−4

Answer:

y = -4x + 4

Step-by-step explanation:

y = (1/4)x - 1

m = (1/4)

Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/4)

                                                                      [tex]= (-1)*\frac{4}{1}\\\\=-4[/tex]

(3 , -8)

y - y1 =m(x -x1)

y -[-8] = -4(x - 3)

y + 8 = -4x + 12

    y = -4x + 12 - 8

    y = -4x + 4

Answer:

two points

Step-by-step explanation:

x intercepts

Answer:

The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1) . This video shows you how to solve a quadratic equation by factoring.

Answer: 7 / 18

Step-by-step explanation:

There were 18 students.

Out of them, the scores above 65 are:

73, 73, 69, 68, 71, 76, 70

There are 7 of them.

Probability of picking someone who scored higher than 65 is:

= Number of people who scored above 65/ Total number who took the test

= 7 / 18

Answer:

In my opinion both of the lines are tangent.

Step-by-step explanation:

Because a tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.

Answer:

Angles opposite one another that share a vertex are called vertical angles.

When one of these angles undergo a rigid transformation so that it fits exactly over the other, we know that the two angles are congruent

When two parallel lines are crossed by another line called the transversal the angles created inside the parallel lines but on opposite sides of the crossing lines are called alternate interior angles. Angles of this type have the same measurement as one another. Two figures are similar if one can fit exactly over the other after rigid transformations and dilations

Step-by-step explanation:

Vertically opposite angles are always equal (congruent)

The transversal line is the line that crosses two or more parallel lines

Alternate interior angles formed by two parallel lines crossed by a common transversal, are congruent

Two plane geometric figures are similar if they their corresponding interior angles are congruent

Answer:

yes

Step-by-step explanation:

as long as the two shortest sides add up to more than the longest side then a triangle can be made with those side lengths

Answer:

11.2m

Step-by-step explanation:

Using Pythagoras,

a²+b²=c²

10²+b²=15²

100+b²=225

b²=225-100

b²=125

b=√125

b=11.2m

They are both roots of the equation.

Answer:the triangle has (2,) and (0, 4) as its vertices for a maximum area

Step-by-step explanation:let P(x,0) be the x-intercept and Q(0,y) be the y-intercept

label (1,2) as A(1,2)

the slope AP = slope AQ

-2/(x-1) = (2-y)/1

2x - xy - 2 + y = -2

y(1-x) = -2x

y = -2x/(1-x) or 2x/(x-1)

H^2 = x^2 + y^2

= x^2 + ( (2x/(x-1) )^2 --- simplify if needed

(don't know why we are finding the hypotenuse ? )

Area of triangle OPQ

= (1/2)base x height

= (1/2)xy

= (1/2)x(2x/(x-1))

= (1/2) (2x^2/(x-1) )

dA/dx = (1/2) [ (x-1)(4x) - 2x^2(1) ]/(x-1)^2

= (1/2) [ 4x^2 - 4x - 2x^2 ]/(x-1)^2

= 0 for a max of A

2x^2 - 4x = 0

x(2x-4) = 0

x=0 ---- > makes no sense, look at diagram

or

x = 2

then y = 2(2)/(2-1) = 4

the triangle has (2,) and (0, 4) as its vertices for a maximum area

Answer:

The graph shows a LOGARITHMIC function that is asymptotic to X=1

Step-by-step explanation:

Answer:

the height is 2.5 cm

Step-by-step explanation:

The computation of the height of the triangular section is shown below:

As we know that

Volume = One-half × base × height

35 = One-half × 4 × height × 7

So, the height is 2.5 cm

Answer:

Height = 2.5cm

Step-by-step explanation:

Volume = Base(b) x Height(h) x Length(l) / 2

Substitute the information that you have into the equation

Volume = 4 x Height(h) x 7 / 2

Height = 4x7 / 2

= 14cm

35 / 14

= 2.5cm

Step-by-step explanation:

6. You're gonna use Cos to find Y

Cos = adj/hyp

Cos 27 = 10/y

10/cos27 = y

11.2 = y

7. It'll help immensily if you draw this one out.

You're gonna use Sin to find the angle.

Sin = opp/hyp

Sin 65 = 14/x

14/sin65 = x

15.4 = x

Answer:

d = - 22

Step-by-step explanation:

- 18 = d + 4 ( subtract 4 from both sides )

- 22 = d

Answer:

C = 2½ miles.

Step-by-step explanation:

Let the total distance be A

Let the distance covered be B.

Let the unknown distance (distance left) be C.

Given the following data;

A = 3¾ miles

B = 1¼ miles

To find the distance left to hike;

A = B + C

Substituting into the equation, we have;

3¾ = 1¼ + C

C = 3¾ - 1¼

C = (3 - 1) ¾ - ¼

C = 2 2/4

C = 2½ miles.

Method II.

We would convert the mixed fraction into a proper fraction:

A = 3¾ = (4*3 + 3)/4 = 15/4

B = 1¼ = (4*1 + 1)/4 = 5/4

C = 15/4 - 5/4

C = 10/4

C = 5/2

C = 2½ miles.
