Find the slope of the line y = 5/8x - 1/2
Answer:
slope = [tex]\frac{5}{8}[/tex]
Step-by-step explanation:
Slope-intercept form is the way in which an equation is written to easily identify the line's slope and y-intercept. It is represented by the equation y = mx + b, in which m represents the slope.
By looking at the equation, we can see that it takes the y = mx + b format - y is isolated - therefore it is in slope-intercept form. Remember that the number in place of the m would represent the slope - and in this case, that number is [tex]\frac{5}{8}[/tex].
Final Answer:
[tex]\sf{Slope = \dfrac{5}{8}}\\\sf{Y-intercept: -\dfrac{1}{2}}[/tex]
In-depth explanation:
The question is asking us to find the slope of the line, whose equation is;
[tex]\leadsto\quad\bf{y=\dfrac{5}{8}x-\dfrac{1}{2}}[/tex]
The format of this equation is: [tex]\boldsymbol{\sf{y=mx+b}}[/tex]. This is known as slope-intercept; it's the most common way of writing the equation of a line.
In y = mx + b, the variable "m" denotes the slope, or the rate of change, of a line; b denotes the y-intercept, or the point where the line intercepts the y-axis.
Also, the slope is the number before x, while b is the constant term.
Similarly, the slope is 5/8 and the y-intercept is -1/2.

If sin θ>0 and tan θ<0, in which quadrant does the terminal side of θ lie?
Answer:
Quadrant IV
Step-by-step explanation:
For an angle in the fourth quadrant the point P has positive x coordinate and negative y coordinate. Therefore: In Quadrant IV, cos(θ) > 0, sin(θ) < 0 and tan(θ) < 0 (Cosine positive). The quadrants in which cosine, sine and tangent are positive are often remembered using a favorite mnemonic.

What is the measure of the angle in red?
Answer:
B
Step-by-step explanation:
The red line is almost 360 degrees.
If you subtract 65 from 360 you get 295
When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of the angle in red is 295°. The correct option is B.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
The total angle at a point is always equal to 360°. Given that the measure of the green angle is 65°.
But as it can be seen that the red angle and the green angle together form a complete rotation of 360°. Therefore, the sum of the two angles can be written as,
Red angle + Green angle = 360°
Red angle + 65° = 360°
Red angle = 360° - 65°
Red angle = 295°
Hence, the measure of the angle in red is 295°.

a) Work out the value of G
give your answer in standard form correct to 3 significant figures
b) Work out the new value of G
give your answer in standard form correct to 3 significant figures
Answer:
a. G = 4590.0
b. G = 4550.0
Step-by-step explanation:
Given that: G = [tex]\sqrt{\frac{m}{t^{2} } }[/tex]
a. m = 6.1 x [tex]10^{-5}[/tex] and t = 1.7 x [tex]10^{-6}[/tex]
Thus,
G = [tex]\sqrt{\frac{6.1*10^{-5} }{(1.7*10^{-6}) ^{2} } }[/tex]
= [tex]\sqrt{\frac{6.1*10^{-5}}{2.89*10^{-12} } }[/tex]
= [tex]\sqrt{21107266.44}[/tex]
G = 4594.26452
G = 4590.0
b. m = 6.1 x [tex]10^{-5}[/tex] + ( 6.1 x [tex]10^{-5}[/tex] x 0.08)
= 6.588 x [tex]10^{-5}[/tex]
t = 1.7 x [tex]10^{-6}[/tex] + (1.7 x [tex]10^{-6}[/tex] x 0.05)
= 1.785 x [tex]10^{-6}[/tex]
So that,
G = [tex]\sqrt{\frac{6.588*10^{-5} }{(1.785*10^{-6}) ^{2} } }[/tex]
= [tex]\sqrt{\frac{6.588*10^{-5} }{3.186*10^{-12} } }[/tex]
= [tex]\sqrt{20676505.9}[/tex]

$85 bill before tax
Discount:25%
Tax:6.4%
Answer:
$67.83
Step-by-step explanation:
Price before tax: $85
Discount: 25%
100% - 25% = 75% = 0.75
Price after discount: 0.75 * $85 = $63.75
Tax: 6.4%
100% + 6.4% = 106.4% = 1.064
Price after discount & tax: 1.064 * $63.75 = $67.83

Mariah bought 5 shirts that each cost the same amount and a pair of jeans that cost $30. She spent a total of $150 at the store. Write an equation to determine the cost of each shirt.
Answer:
150-30=5x
Step-by-step explanation:
If the total is $150 and a pair of jeans is $30, then you'd subtract them. Since you have to find out how much each shirt is, you'd put 5x on the other side of the equal sign. Then solve for X.

Circumference of a circle is given by,
C = 2πr
25π = 2πr
Dividing both sides by 2π

Suppose y varies directly with x when x is 4, y is 32. What is y when x is -2
Step-by-step explanation:
Since y varies directly with x,
y = kx, where k is a real constant.
When x = 4, y = 32.
=> (32) = (4)k, k = 8.
Therefore when x = -2,
y = kx = (8)(-2) = -16.
