Answer:

43.5 cm² and 112 cm²

Step-by-step explanation:

Here the instructions aren't given what to do. So I am finding the area of the ∆s .

Area of first ∆ :-

Area of second ∆ :-

Answer:

[tex] \displaystyle 3) \boxed{ \rm {43.5 \: cm}^{2} }[/tex]

[tex] \displaystyle 4)\rm \boxed{112 {cm}^{2} }[/tex]

Step-by-step explanation:

we are given a triangle and we want to figure out the area of it Since we are given the base and the height we can consider the following formula

[tex] \displaystyle \frac{1}{2} bh[/tex]

from the triangle we can assume base and height as 14.5 and 8 respectively Thus substitute:

[tex] \displaystyle \frac{1}{2} (14.5cm)(6cm)[/tex]

reduce fraction:

[tex] \displaystyle (14.5cm)(3cm)[/tex]

simplify multiplication:

[tex] \displaystyle \boxed{ \rm {43.5 \: cm}^{2} }[/tex]

our given shape is trapezoid

therefore recall that,

[tex] \displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h[/tex]

from the shape we define that

now substitute:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = \frac{9cm + 19cm}{2} (8cm)[/tex]

reduce fraction:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = (9cm + 19cm)(4cm)[/tex]

simplify addition:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = (28cm)(4cm)[/tex]

simplify multiplication:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = \boxed{112 {cm}^{2} }[/tex]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x

Consider the left side

[tex]\frac{cosA}{1-sinA}[/tex] ← multiply numerator/denominator by (1 + sinA)

= [tex]\frac{cosA(1+sinA)}{(1-sinA)(1+sinA)}[/tex] ← expand denominator using FOIL

= [tex]\frac{cosA(1+sinA)}{1-sin^2A}[/tex]

= [tex]\frac{cosA(1+sinA)}{cos^2A}[/tex] ← cancel cosA on numerator/ denominator

= [tex]\frac{1+sinA}{cosA}[/tex]

= right side , thus proven

Answer:

I use equal signs throughout but they are meant to be less than or equal to signs.

s=sandwiches

4.5s+6 less than or equal to 50

The answer is s is less than or equal to 12

Step-by-step explanation:

Finding Inequality

1. we know everything costs 50 in total so that is on one side of the equal sign.

____=50

2. we know he already spent 6 dollars so the money he can spend is 6 dollars less.

____+6=50

3. Each sandwich costs 4.50 $ so how much money does he have left to spend? we figure that out by multiplying the price by the number of sandwiches.

4.5s+6=50

Solving

1. 4.5s-6=50

First use the addition property of equality and add 6 to both sides.

2. 4.5s=56

Then use the division property of equality and divide each side by 4.5

3. you get a decimal but since you can't buy half a sandwich the answer is

s is less than or equal to 12

Answer:

Y= 1/3x-15

Step-by-step explanation:

-6=-3(-3)+b

-6= 9+b

subtract 9 on both sides

b= -15

Y= 1/3x-15

because its perpendicular the -3x become positive and reciprocal

Answer:

Y= 1/3x-15

Answer:

9.2

Step-by-step explanation:

S.A.S.→Law of Cosines

a^2=b^2+c^2-2bc\cos A

From reference sheet.

h^2 = 9.2^2+1.4^2-2(9.2)(1.4)\cos 84

=84.64+1.96−2(9.2)(1.4)(0.104528)

Square and find cosine.

h^2 = 84.64+1.96-2.69265

h  

2

=84.64+1.96−2.69265

Multiply.

h^2 = 83.90735

h  

2

=83.90735

Add.  

h=  

83.90735

​  

≈9.16≈9.2

The required measure of the length of h is 9.2 centimeters.

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

here,

Law of Cosines

In ΔHIJ, i = 9.2 cm, j = 1.4 cm and ∠H=84°

Following the cosine rule

a²=b²+c²-2bc×cos A

From given

h² = 9.2²+1.4²- 2(9.2)(1.4) × cos 84

h² = 84.64+1.96-2.69265

h²  = 84.64+1.96 −2.69

h² = 83.9

h ≈9.2

Thus, the required measure of the length of h, to the nearest 10th of a centimeter is 9.2 centimeters.

Have a nice day:)

Step-by-step explanation:

The formula for the slope is y=mx+b, where m is the slope and b is the y-intercept. Since 2 is being multiplied by x, that means it is the slope. The variable y is being added, so it has to be the y-intercept.

Answer:

2=slope & y-intercept=y

Answer:

the slope is -2 and the y-intercept is 3

Step-by-step explanation:

you can rearrange the equation into y=mx+b form which will be y = -2x + 3

the m in y=mx+b is the slope, which in this case is -2.

and the y-intercept is 3 bc is the only constant in the equation.

Answer:

43.75 mph

Step-by-step explanation:

Divide 75 by 4 and divide 4 by 4 which gets the unit rate

The unit rate that represents 175 miles in 4 hours​ is 43.75 miles per hour.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, The distance covered in 4 hours in 175 miles.

We know, Distance = speed×time.

Therefore, 175 = 4×s.

s = 175/4.

s = 43.75 miles per hour.
