Step-by-step explanation:

Answer:

Area of rectangle = 54

Area of triangle= 18

Total area = 72

Step-by-step explanation:

Area of rectangle = length × width

= 9 × 6

= 54

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

[ Height of the triangle = 10 - 6 = 4 ]

Area of a triangle = [tex]\frac{1}{2}[/tex] × 9 × 4

= 18

Total area = Area of rectangle + Area of triangle

= 54 + 18

= 72

[ The unit should be: [tex]cm^{2}[/tex] or [tex]m^{2}[/tex] etc.; it should have the 'square'. ]

Step-by-step explanation:

Answer:

hypotenuse =13cm

base=10cm

perpendicular =?

Step-by-step explanation:

by using Pythagoras law

hypotenuse=perpendicular²+base²

13²=perpendicular²+10²

perpendicular =√(13²-10²)=√69=8.3cm

the measure of the other leg is 8.3cm

The measure of the other leg is 8.3 cm .

The Pythagoras theorem states that if a triangle is right-angled (90 degrees), then the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Formula of Pythagoras theorem :

(Hypotenuse)² = (Base)² + (Perpendicular)²

According to the question

Hypotenuse of a right triangle = 13 cm

Perpendicular of a right triangle = 10 cm

Now,

Base of a right triangle  

By using formula of Pythagoras theorem :

(Hypotenuse)² = (Base)² + (Perpendicular)²  

Substituting the values

(13)² = (Base)² + (10)²  

169 = (Base)² + 100

69 = (Base)²

Base = [tex]\sqrt{69}[/tex]

Base = 8.3 cm

Hence,  the measure of the other leg is 8.3 cm .

Answer:

a. 8,250

b. 0

Step-by-step explanation:

a) -2,750 (5) = -13, 750 + 22,000 = 8,250

b) -2,750 (8) = -22,000 + 22,000 = 0

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The worth of the car after 5 years is $8350

The worth of the car after 8 years is $0.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 5 = 8 is an equation.

We have,

The straight-line depreciation equation for a car is

y = -2,750x + 22,000.

The worth of the car after 5 years.

= -2750 x 5 + 22000

= -13750 + 22000

= 8350

The worth of the car after 8 years.

= -2750 x 8 + 22000

= -22000 + 22000

= 0

Thus,

The worth of the car after 5 years is $8350

The worth of the car after 8 years is $0.

Answer:

s = 2j

Step-by-step explanation:

Given - Ada makes sparkling juice by mixing 2 cups of sparkling water

            with every 4 cups of apple juice. Let s represent the number of

            cups of sparkling water and j represent the number of cups of

             apple juice.

To find - Write an equation that shows how s and j are related.

Proof -

Let total number of cups of sparkling water make = s

     Total number of cups of apple juice make = j

Now,

Given that, Ada makes sparkling juice by mixing 2 cups of sparkling water with every 4 cups of apple juice.

⇒2s = 4j

⇒s = 2j

∴ we get

Ada can makes sparking water by mixing 2j cups of sparking water with every j cups of apple juice.

Answer:

Step-by-step explanation:

The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle

Two Angles are Supplementary when they add up to 180 degrees.

Two Angles are Complementary when they add up to 90 degrees

Let the angle = x

Supplement of the angle = y

The supplement of an angle is 80° less than three times the measure of the complement of the angle find the measure of the supplement of the angle

x - 180 = 3(x - 90)

x - 180 = 3x - 270

Collect like terms

3x - x = 270 - 180

2x = 90

x = 90/2

x = 45

x+ y = 180

45 + y = 180

y = 180 -45

y = 135

x in (-oo:+oo)

y = (5/4)*x-(7/4) // - (5/4)*x-(7/4)

y-((5/4)*x)+7/4 = 0

(-5/4)*x+y+7/4 = 0

y-5/4*x+7/4 = 0 // - y+7/4

-5/4*x = -(y+7/4) // : -5/4

x = (-(y+7/4))/(-5/4)

x = 4/5*(y+7/4)

x = 4/5*(y+7/4)

Answer:

(p - 5)(p + 1)

Step-by-step explanation:

Given

p² - 4p - 5

Consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)

The factors are - 5 and + 1 , since

- 5 × + 1 = - 5 and - 5 + 1 = - 4, then

p² - 4p - 5 = (p - 5)(p + 1) ← in factored form

The standard form of a trinomial is

ax² + bx + c ( a ≠ 0 )

p² - 4p - 5 ← is in standard form

with a = 1, b = - 4 and c = - 5

Answer:

function is [tex]y = 3 (6^{x})[/tex]

Step-by-step explanation:

The general form for an exponential function is [tex]y = kb^{x}[/tex].   We need to find both k and b

(0, 3) is a point on the graph.  So, let's substitute 0 in for x and 3 in for y

[tex]3 = k b^{0} = k(1) = k[/tex]

Now we know that k = 3

(1, 18) is a point on the graph.  So, let's substitute 1 in for x, 18 in for y and 3 in for k

[tex]18 = 3 b^{1} = 3b\\6 = b[/tex]

Now we know that b = 6

Therefore, the function is [tex]y = 3 (6^{x})[/tex]
