help with both question plz!

Answer:

Step-by-step explanation:

a right angle contains 90° (always)

according to the question

x+3+x-1+x+1=90

3x3=90

x=87

x=29

When looking at the following expression, we can tell that it has no rational roots. However, it does have zeros at:

t = -0.45, 2.16, 12.29.

When thinking of the cubic curves you know that p(t) < 0 for 2.16 < t < 12.29. Meaning the team took a loss in years 3-12.

Please consider me brainliest.

it's helpful ya lol :)

I think it's 17 :(

Answer:

Step-by-step explanation:

4x-2 +3x+7 = 180

7x + 5 = 180

7x = 175

x = 25

3(25) + 7 = 82

Answer:

82 (degrees)

Step-by-step explanation:

4x-2+3x+7=180=7x+5...175=7x...x=175/7... x=25

This is both angles combined which we know adds up to half of the entire quadrilateral (180 degrees). Then solve.

3(25) +7=82 which is equal to f

f=82

Answer:

4w-  4

Step-by-step explanation:

Answer:

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

Step-by-step explanation:

Solve the equation for X

[tex]\left \{ {{x=-5/3+4/3y} \atop {5x+8y=-1}} \right.[/tex]

Substitute the given value of x into the equation 5x + 8y = -1

5(-5/3+4/3y)+8y=-1

Solve the equation for Y

y=-1/2

Substitute the given value of y into the equation x = -5 / 3 + 4 / 3y

x=-5/3+4/3×1/2

Solve the equation for X

x=-1

The system solution is the computer pair

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

Check if the ordered pair given to the solution of the system of equations

[tex]\left \{ {{3*(-1)-4*1/2=-5} \atop {5*(-1)+8*1/2=-1}} \right.[/tex]

Simplify the equations

[tex]\left \{ {{-5=-5} \atop {-1=-1}} \right.[/tex]

The ordered pair is the solution of the system of equations, since both equations are true

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

Answer:

[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

Step-by-step explanation:

equation of line formula:

[tex]y = mx + c[/tex]

m = slope

c = y-intercept

1) find m

slope formula:

[tex]m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]

take 2 coordinates from the given graph and substitute the values into the slope formula

i) (-1,0)

[tex]x _{1} = - 1[/tex]

[tex]y_{1} = 0[/tex]

ii) (3,2)

[tex]x_{2} = 3[/tex]

[tex]y_{2} = 2[/tex]

substitute the values into the slope formula

[tex]m = \frac{2 - 0}{3 - ( - 1)} [/tex]

[tex]m = \frac{2}{4} [/tex]

[tex]m = \frac{1}{2} [/tex]

2) find the half equation of the line by substituting the value of m into the equation of line formula

[tex]y = \frac{1}{2} x + c[/tex]

3) find c by substituting either coordinate into the half equation

(3,2)

x = 3

y = 2

[tex]2 = \frac{1}{2} (3) + c[/tex]

[tex]2 = \frac{3}{2} + c[/tex]

[tex]2 - \frac{3}{2} = c[/tex]

[tex] \frac{1}{2} = c [/tex]

[tex]c = \frac{1}{2} [/tex]

4) find equation of line by substituting the value of c into the half equation

[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

Answer:

The answer is C

Step-by-step explanation:

Answer:

43.2 years

Step-by-step explanation:

The formula for continuously compounded interest on a principal investment Pat a given interest rater

over time tin years is given by A = Pe^rt

P = Initial amount compounded = $12000

A = Amount compounded continuously after t years = six times it's original worth

= 6 × $12,000 = $72000

r = Interest rate = 4.15%

t = time in years = ?

Making t the subject of the formula

t = ln(A/P) / r

First, convert R percent to r a decimal

r = R/100

r = 4.15%/100

r = 0.0415 per year,

Then, solve our equation for t

t = ln(A/P) / r

t = ln(72,000.00/12,000.00) / 0.0415

t = 43.175 years

Approximately t = 43.2 years

The time required to get a total amount of $ 72,000.00 from compound interest on a principal of $ 12,000.00 at an interest rate of 4.15% per year and compounded continuously is 43.2years.

Answer:

x=2

Step-by-step explanation:

Answer:

Width=9.5, Length=32.5

Step-by-step explanation:

Let x be the width of the rectangle,

The length is 4 feet more than 3 times the width,

The length= 3x+4

The perimeter is

2(x)+2(3x+4)=84

2x+6x+8=84

8x=76

x=76/8

x=9.5

The Width=9.5

Length= 3(9.5)+4=32.5

Answer:

The amount is $2137.24 and the interest is $237.24.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A = P[tex](1+\frac{x}{y} )nt[/tex]

A = total amount P = principal or amount of money deposited, r = annual interest rate n

= number of times compounded per year t = time in years In this example we have

P = $1900 , r = 4% , n = 1 and t = 3 years

After plugging the given information we have

A = 1900 [tex](1+\frac{0.04}{1})^{1*3}[/tex]

A = 1900 · 1.0[tex]4^{3}[/tex]

A = 1900 · 1.124864

A = 2137.24

STEP 2: To find interest we use formula A = P + I, since A = $2137.24 and P = $1900 we

have:

A = P + I

2137.24 = 1900 + I

I = 2137.24 − 1900

I = 237.24

Answer:

Solve for  x  by simplifying both sides of the equation, then isolating the variable.

Exact Form: x  =  34 /3

Decimal Form:  x  =  11. ¯  3

Mixed Number Form:  x  = 11  1 /3

Answer:

$1954

Step-by-step explanation:

Given the profit function expressed as;

y=-3x^2 + 197x – 1279

The profit is at maximum when dy/dx = 0

dy/dx = -6x + 197

0 = -6x+197

6x = 197

x = 197/6

x = 32.83

substitute 32.83 into the modeled function

y=-3x^2 + 197x – 1279

y -3(32.83)²+197(32.83) - 1279

y = -3(1,078.03)+6,467.51 - 1279

y = -3,234.09+6,467.51-1279

y = 1,954.42

hence the maximum amount of profit the company can make, to the nearest dollar is $1954
