Answer:
0
Step-by-step explanation:
tan0 •sin 0+ cot0 •sin0 =
tan(0) • sin(0) + cot(0) • sin(0) =
(tan(0) × sin(0)) + (cot(0) × sin(0)) =
(0 × 0) + (0 × 0) = 0 + 0 = 0
. A gas station is charging $3 per gallon for gasoline. Let x represent the amount (in gallons) of gasoline purchased, and let f(x) represent the cost (in dollars) of x gallons of gasoline. A. Evaluate f(10) and f(15). B. When (i.E. For what value of x) is f(x) = 21?
Answer:
(A) F(10) = 30, F(15) = 45
(B) x = 3
Step-by-step explanation:
According to the scenario, calculation of given data are as follows,
Charge for 1 gallon = $3
Amount of gasoline purchased = x
and x gallons cost = f(x)
So, cost for 1 gallon = f(x) ÷ x = 3
or f(x) = 3x
(A). So, for F(10)
Put value of F as 3, then
F(10) = 3 × 10 = 30
Similarly, for f(15) = 3 × 15 = 45
(B) f(x) = 21
we can put the value of f as 3, and then find the value of x,
3 (x) = 21
x = 21 ÷ 3
x = 7

Let q= (15,-3), r= (-5,8), and S = (10.-1). What is r- 9+2s? (0.3) 0 (0.9) 0 (40.3) 0 (40.-13)
Answer: The value of r- q+2s is (0,9).
Step-by-step explanation:
Given: q= (15,-3), r= (-5,8), and S = (10,-1)
To find: r- q+2s
Consider r- q+2s = (-5,8) - (15,-3) + 2x (10,-1)
= (-5,8) - (15,-3) +(2 x 10, 2 x -1) [ a(b,c) = (ab, ac)]
= (-5, 8) - (15,-3) + (20,-2)
= (-5-15+20, 8-(-3)+(-2)) [(a,b)+(c,d)= (a+c, b+d)]
= (-20+20, 8+3-2)
= (0, 9)
Hence, the value of r- q+2s is (0,9).

The cost of two pounds of cherries is
$8.58. What is the unit rate that describes the
cost per pound of cherries?
Answer:
since you have 2 pounds, and spend $8.58 total, divide the amount you spent, but how many pounds you bought to get the unit rate which is $4.29
Step-by-step explanation:
Answer:
$4.29 per pound
Step-by-step explanation:
(8.58 dollars)/(2 pounds) = ((8.58/2) dollars)/pound =4.29 dollars/pound
The coordinates (5, 2) and (–6, 2) are vertices of a hexagon. Explain how to find the length of the segment formed by these endpoints. How long is the segment?
Answer:
Step-by-step explanation:
Let
Point 1 ----------> (5, 2)
Point 2 ----------> (–6, 2)
we know that
the distance between two points it is calculated with the formula
d=√[(y2-y1)²+(x2-x1)²]
then
d=√[(2-2)²+(-6-5)²]
d=√[(0)²+(-11)²]
d=√[121]
d=√121-----------> d=11 units
the answer is 11 unit
Answer:
Sample Response: The segment is horizontal because the y-coordinates are the same. To find the distance, you can count the spaces between the points. The segment is 11 units long.

Answer:

Step-by-step explanation:
We need to find the hypotenuse of the blue triangle, as stated in the hint. We know the sides of the base measure 8 x 15 respectively so let's use Pythagorean Theorem;
8^2 + 15^2 = (hyp.)^2,
hyp = √8^2 + 15^2 = √64 + 225 = √289 = 17
Now the height of the yellow triangle is 10 inches. The hypotenuse of the blue triangle is now the base of the yellow triangle. The dimensions are 10 x 17 respectively so we can determine it's hypotenuse;
hyp (yellow triangle) = √17^2 + 10^2
= √289 + 100
= √389 ≈ 19.7 in.

Select the procedure that can be used to show the converse of the pythagorean theorem using side lengths chosen from 5cm, 9cm, 12 cm, and 13 cm.
please help I am stuck on this one.
Answer:
It's A
Step-by-step explanation:
The procedure that can be used to show the converse of the Pythagorean theorem is - 'Knowing that [tex]5^{2}+12^{2}=13^{2}[/tex] draw the 5 cm side and 12 cm side with a right angle between them. The 13 cm side will fit to form a right triangle.'
The correct answer is an option (D)
What is right triangle?"It is a triangle whose one of the angle measures 90° "
What is converse of the Pythagorean theorem?"If the square of a side of a triangle is equal to the sum of the square of the other two sides, then triangle must be right angle triangle."
For given question,
We have been given the side lengths 5cm, 9cm, 12 cm, and 13 cm.
We need Select the correct procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 5cm, 9cm, 12 cm, and 13 cm.
We can observe that,
[tex]5^{2} +12^{2}\\ =25+144\\ =169\\=13^2[/tex]
This means, draw the 5 cm side and 12 cm side with a right angle between them. Then, the 13 cm side will fit to form a right triangle.
Therefore, the procedure that can be used to show the converse of the Pythagorean theorem is - 'Knowing that [tex]5^{2}+12^{2}=13^{2}[/tex] draw the 5 cm side and 12 cm side with a right angle between them. The 13 cm side will fit to form a right triangle.'

Can any1 answer this? I need help, asap. :(
Answer:
y = -4x + 5
Step-by-step explanation:
Linear Formula: y = mx + b
b: The line touches the Y-axis at the fifth unit (0,5)
m: Using the rise-over-run method; the line can be seen going from the coordinates (0,5) to (1,1). Moving from (0,5) to (1,1), you move the plot 4 units downwards and 1 unit to the right; 4/1 = 4. Since the line is sloping downward, the line entire slope value would be -4
With m = -4 and b = 5; your equation is y = -4x + 5
