Answer:

x = -2 & x = 1

Step-by-step explanation:

Answer:

well, I think it is B 7°

as X =7

because 5x=3x+14

so 5x7= 35

3x7=21 + 14=35

Answer:

A formula for P(x) is;

P(x) = -0.8·x³ + 0.8·x² + 0.8·x - 0.8

Step-by-step explanation:

The given parameters of the polynomial are;

The degree of the polynomial = 3

The multiplicity of the root at x = 1 is 2

The multiplicity of the root at x = -1 is 1

The y-intercept is y = -0.8

Therefore, we have to find the formula for the three degree polynomial;

The factors of the three degree polynomial are (x - 1)², and (x + 1)

Multiplying the factors together, we get;

(x - 1)²×(x + 1) = x³ - x² - x + 1

f(0) = -0.8, therefore, we get;

P(x) = -0.8 × (x - 1)² × (x + 1) = -0.8·x³ + 0.8·x² + 0.8·x - 0.8

The required polynomial is;

P(x) = -0.8·x³ + 0.8·x² + 0.8·x - 0.8

Answer:

the coordinates of the centroid of the triangle with the vertices A(-6,8), B(-3,1),andC(0,3).

={(-6-3-0)/3,(8+1+3)/3}=(-3,4)

Answer:

( - 3, 4 )  

Step-by-step explanation:

The centroid of a triangle is the intersection of the three medians of the triangle.

A ( - 6, 8 )

C ( 0, 3 )

Coordinates of the midpoint of AC are D( - 3, 5.5 )

Median BD is x = - 3

Coordinates of midpoint of BC are E( - 1.5, 2 )

[tex]m_{AE}[/tex] = - [tex]\frac{4}{3}[/tex]

Equation of median AE is y = - [tex]\frac{4}{3}[/tex] x

Solve system of equations:

y = - [tex]\frac{4}{3}[/tex] x and x = - 3

( - 3, 4 ) are coordinates of the centroid of the Δ ABC

Answer:

AC=42

EB=21

BC=26

thats all i know, sorry hope u figure it out

Step-by-step explanation:

The sides are AC = 42, EB = 21, BC = 26, AB = 38 and the measures of angles are ∠ADC = 90°, ∠ABD = 38°, ∠BCA = 52°, ∠DEC = 104°.

Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles

Given is a rectangle ABCD.

AC and BD are diagonals intersecting at E.

Given  DB=42, AD=26 and m ∠DAE=52°

(a) Diagonals of a rectangle are of equal length.

AC = DB = 42

(b) Diagonals of a rectangle bisect each other.

DE = EB = DB / 2 = 42/2 = 21

(c) Opposite side are equal.

BC = AD = 26

(d) Using Pythagoras theorem,

AB = [tex]\sqrt{(AC)^2-(BC)^2}[/tex] = [tex]\sqrt{42^2-26^2}[/tex] = 37.947 ≈ 38

(e) Measure of all the interior angles in a rectangle is 90°.

So, ∠ADC = 90°

(f) Given ∠DAE = 52°

∠BAE = 90° - 52° = 38°

ΔBAE is an isosceles triangle, since the two sides which are the bisectors of the diagonals are equal.

So, ∠ABD = ∠BAE = 38°

(g) ∠BCA = ∠DAE [Alternate interior angles]

∠BCA = 52°

(h) Sum of interior angles of a triangle is 180°.

∠DEC + ∠BDC + ∠ACD = 180°

∠BDC = ∠ABD = 38° and ∠ACD = ∠BAE = 38°

∠DEC = 180° - (38° + 38°)

          = 104°

Hence the measures are found.

Answer: B. 6 rides

Step-by-step explanation:

To find this out, deduct all the expenses mentioned from the amount Daniel came to the park with.

= 79.5 - 31.75 - 9.25 - 5.50

= $33.00

Daniel has $33.00 to spend on rides.

If each ride costs $5.50, the number of rides he can go on is:

= 33 / 5.5

= 6 rides

Answer:

6/11

Step-by-step explanation:

let r be 0.54545454

multiply both sides by ten

10r = 5.4545454

since after the decimal point the digits between r and 10r are nor equal, we multiply again both sides by ten

100r = 54.54545454

since the digits after the decimal point between r and 100r are equal, we subtract the two

100r - r = 54.54545454 - 0.54545454

99r = 54

divide both side by 99

99r/99 = 54/99

through further simplification

r = 6/11

Step-by-step explanation:

Answer:

y = 3

Step-by-step explanation:

y - 3 = 2(x + 1)

If you simplify the right side of the equal sign, you'll get...

y - 3 = 2x + 2

then you would add 3 to both sides...

y - 3 (+3) = 2x + 2 (+3)

which will make...

y = 2x + 5

and since x = -1, you plug it in..

y = 2(-1) + 5

which will give you..

y = -2 + 5

which will make it..

y = 3

Answer:

60m³b²

Step-by-step explanation:

We need to find the least common multiple of 15 m³ and 12 b².

Prime factorization of 15 m³ = 3×5×m³

Prime factorization of 12 b² = 3×2×2×b²

Common = 3×5×m³×2×2×b²

= 60m³b²

So, the least common multiple of 15 m³ and 12 b² is equal to 60m³b².

Answer:

p=70+1.25x

Step-by-step explanation:

Answer:

P=1.25x+70

Step-by-step explanation:

So we know that Aaliyah earns $1.25 commission for every computer she sells. No matter what, she will make $70 per day, so that would be our constant. The $1.25 would be our independent variable since it can change depending on the amount of computers x she sells. Therefore, our equation is:

P represents the total pay, 1.25x represents the total commission for x computers, and the 70 is the base pay.

P=1.25+70
