d) 42.0​

A) 25.8b) 36.8c) 64.2d) 42.0

Answers

Answer 1

Answer:

y = 25.8

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos y = adjacent/ hypotenuse

cos y = 18/20

Take the inverse cos of each side

cos ^-1 (cos y) = cos^-1(18/20)

y =25.84193276

Rounding to the nearest tenth

y = 25.8

What is Linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The function is,

y = 4x - 1

Now, The graph of function y = 4x - 1 is shown in image.

And, At y = 1;

By the graph the value of x = 1/2.

And, In mathematically;

At y = 1

The value of x is;

y = 4x - 1

1 = 4x - 1

4x = 2

x = 2/4

x = 1/2

Thus,

a) The graph of y = 4x - 1 is shown in attached image.

b) By using the graph at y = 1 the value of x is 1/2.

Rewrite the radical expression as an expression with rational exponents.

cube root of x to the power of 8

Answers

Answer: [tex](\sqrt[3]{x} )^8[/tex]

Step-by-step explanation:

Radical expression :

Cube root of any expression 'a' = [tex]\sqrt[3]{a}[/tex]

Radical exponent:

'a' to the power n = [tex]a^n[/tex]

Similarly cube root of x = [tex]\sqrt[3]{x}[/tex]

cube root of x to the power of 8 = [tex](\sqrt[3]{x} )^8[/tex]

Now , the required radical expression with rational exponents for "cube root of x to the power of 8" = [tex](\sqrt[3]{x} )^8[/tex]

Hence, the required expression =[tex](\sqrt[3]{x} )^8[/tex]

Priyanka drives at 45km/h and reaches Delhi in 5 hours.What time will she take to complete the same journey if she increases her speed by 5km/h ?​

Answers

Answer: Increasing her speed  by 5km/h, she will take 4.5 hours to complete the journey.

Step-by-step explanation:

Step 1

Speed= Distance  / TIme

Given Speed = 45km/h

and Time = 5 hours

Distance covered = Speed x Time

= 45 km/h x 5 hours

=225 kilometres.

Step 2

Increasing her speed by 5km/h makes the new Speed = 45 +5 = 50 km/h

At the same Distance of 225 km

Therefore she will complete the journey in

Time = Distance/ Speed

=225km/ 50km/h

=4.5 hours

Explanation:
$2.50 is a one time cost so we want to subtract that from $9.25 to see how many games we can play. This leaves us with $6.75.
Next, we divide $6.75 / $2.25 = 3.
This means the total amount of games one can play is 3.
