Answer:
Hello,
18 x tan 40°
Step-by-step explanation:
tan 40° = BC / AC
and with AC = 18
tan 40° = BC / 18 ⇔ BC = 18 x tan 40°

Final answer:
The slope can be found using the coordinates of the given point and the y-intercept. The equation of the line is y = -2x - 5.
Explanation:
To write the equation of a line with a given y-intercept and a point, we can use the slope-intercept form:
y = mx + b.
The y-intercept is -5, so the equation becomes:
y = mx - 5.
We also know that the line passes through the point (-3, 1). To find the slope (m), we can use the formula:
m = (y2 - y1) / (x2 - x1). Substituting the coordinates, we get:
m = (1 - (-5)) / (-3 - 0)
= 6 / -3
= -2.
Plugging the slope and y-intercept into the equation, the equation of the line is: y = -2x - 5.

1. 3x+(1/14)=(2x)/8 or
2. (3x+1)/14=(2x)/8
if it is 1
1.
3x+(1/14)=2x/8
simplify 2x/8
2x/8=x/4
3x+(1/14)=x/4
find least common multiple of 14 and 4
factors of 14=2 and 7
factors of 4 are 2 and 2 so LCM=2 times 2 times 7=28
multiply both sides by 28
84x+2=7x
subtract 7x from both sides
77x+2=0
subtract 2 from both sides
77x=-2
divide both sides by 77
x=-2/77

(3x+1)/14=2x/8
simpify 2x/8
2x/8=x/4
(3x+1)/14=x/4
find least common multiple of 14 and 4
factors of 14=2 and 7
factors of 4 are 2 and 2 so LCM=2 times 2 times 7=28
multiply both sides by 28
(2)(3x+1)=7x

6x+2=7x
subtract 6x from both sides

Final answer:
By substituting x = 2 into the function f(x) = 2(x)² + 5√(x + 2) and simplifying the equation, the resulting value of f(2) is calculated to be 18.
Explanation:
For the given function f(x) = 2(x)² + 5√(x + 2), we are asked to find the value of f(2). To find this, first substitute x = 2 into the function. So, the calculation becomes
f(2) = 2 * (2)² + 5 * √(2 + 2)
simplifying this equation, we get:
f(2) = 2 * 4 + 5 * √4 = 8 + 5 * 2 = 8 + 10 = 18
So, f(2) = 18

Answer:
$104
Step-by-step explanation:
10% = 160 ÷ 10 = $16
5% = $16 ÷ 2 = $8
30 % = 16 x 3 = $48
48 + 8 = $56
$160 - $56 = $104
Hope this helps!

Answer:
31°C
Step-by-step explanation:
The formula to convert Celsius to Fahrenheit is F=9/5c+32.
To convert 87° F to Celsius plug in F = 87 in the above formula, we get
87 =
Now we have to isolate the variable and the constant.
Subtract 32 from both sides, we get
87 - 32 =
55 =
Multiply both sides by the reciprocal of -9/5
Which is called inverse operations to find the value of C.
The reciprocal of -9/5 is -5/9
C = 275/9
C = 30.5°
To round off to the nearest degree, we get
31°C
