Answer:
Slope is -5 and y-intercept is 90.
Step-by-step explanation:
Use the two values that you circles (4, 70) and (6, 60) .
slope (m) = the change in y-value/ (the change in the x-values).
m = (70 - 60)/(4 - 6) = 10/-2 = -5
The y-intercept is the value of "b" in the equation y = mx + b.
Using y = mx + b, substitute the value m and use point of your points (4, 70).
y = mx + b
70 = -5(4) + b Now solve for "b".
70 = -20 + b
+20 = +20
90 = b

Answer:
-4
Step-by-step explanation:
We are given the equation:-
[tex] \displaystyle \large{x + Cy = \frac{1}{4} }[/tex]
Since we wants to find the value of C that makes the line pass y-intercept which is -1/16.
When we talk about y-intercept, our x-value remains 0 and y-value remains any real number.
It can be expressed as (0,b) point where b is any real numbers.
What we have to do is to substitute (0,-1/16) or x = 0, y = -1/16 in the equation so we can find the value of C.
Thus:-
[tex] \displaystyle \large{x + Cy = \frac{1}{4} } \\ \displaystyle \large{0 + C( - \frac{1}{16} ) = \frac{1}{4} } \\ \displaystyle \large{ - \frac{ C}{16} = \frac{1}{4} }[/tex]
Multiply both sides by GCF.
[tex] \displaystyle \large{ - \frac{ C}{16} = \frac{1}{4} } \\ \displaystyle \large{ - \frac{ C}{16} (16)= \frac{1}{4} (16)} \\ \displaystyle \large{ - C= 4 } \\ \displaystyle \large{ C= - 4 }[/tex]
Therefore, C = -4
solve for a : 24a=8
simplify the answer as much as possible.
Answer:
a=1/3
Step-by-step explanation:
24a=8
Divide both sides by 24, and you will get a=8/24
Divide both the numerator and denominator by 4, and you will get 2/6, which is equivalent to 1/3.
Answer:
a = 1/3
Step-by-step explanation:
Divide both sides of the equation by the same term(24)
24a/24 and 8/24 = a = 1/3
Find the value of arc s
Answer:
≈ 38.64 units
Step-by-step explanation:
The length of arc s is calculated as
circumference of circle × fraction of circle
The central angle subtended by arc s is 360° - 114° = 246° then
arc s = 2πr × [tex]\frac{246}{360}[/tex]
= 2π × 9 × [tex]\frac{41}{60}[/tex]
= 18π × [tex]\frac{41}{60}[/tex]
≈ 38.64 ( to 2 dec. places )

Step-by-step explanation:
I Had Also Taken The Test And It Was 1 7/18 In Mixed Numbers.
The expression 4(19 + e2) + 3f at e = 13 and f = 16 is 804.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, we have to Evaluate the expression 4(19 + e2) + 3f when e = 13 and
f = 16 is the same as replacing the numerical values of e and f in the expression
4(19 + e2) + 3f which is,
= 4(19 + 13²) + 3×16.
= 4(19 + 169) + 48.
= 4(189) + 48.
= 756 + 48.
= 804.

Find the volume of a right circular cone that has a height of 10.6 m and a base with a
diameter of 18.5 m. Round your answer to the nearest tenth of a cubic meter.
The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,
V = 949.76cm³
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Height of cone = 10.6 m
Diameter of cone = 18.5 m
Hence, We can solve for radius as;
= 18.5/2
= 9.25
We know that;
Volume of a right circular cone is,
V = 1/3(πr²h)
Here, r = 9.25, h = 10.6, π = 3.14,
Hence, We get;
V = 1/3(3.14)(9.25)²(10.6)
V = 1/3(3.14)(85.5625)(10.6)
V = 1/3(2847.86225)
V = 949.287417
V = 949.76cm³
Thus, The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,
V = 949.76cm³

A motorboat can maintain a constant speed of 47 mph relative to the water. The boat makes a trip upstream to a certain point in 51 minutes; the return trip takes 43 minutes. What is the speed of the current?
9514 1404 393
Answer:
4 mph
Step-by-step explanation:
The ratio of speeds upstream and down is inversely proportional to the ratio of times upstream and down. If we let c represent the speed of the current, the relation can be written ...
(47 +c)/(47 -c) = 51/43
43(47 +c) = 51(47 -c)
94c = 8(47) . . . . . . . . . . . add 51c -43(47)
c = 4 . . . . . divide by 94
The speed of the current is 4 miles per hour.
Y=a|x-h|+k
11. how does the value of k affect the graph?
12. how does the value of h affect the graph?
13. how do the sign and absolute value of A affect the graph?
Step-by-step explanation:
Given the general form of the absolute value function, y = a|x - h| + k
11. How does the value of k affect the graph?The value of k determines how far up or down the parent function is translated. If k is positive, the function is translated k units up. If k is negative, the function is translated |k | units down.
12. How does the value of h affect the graph?The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right. If h is negative, the function is translated |h | units to the left.
13. How do the sign and absolute value of A affect the graph?The value of a determines whether the graph opens up or down.
If a is positive, the graph opens up.If a is negative, the graph opens down.The value of a also makes the parent function wider or narrower.
If 0 < a < 1, the graph is wider than the parent function.If a > 1, the graph is narrower than the parent function.What is f(4) for the graph shown below?
Answer:
f(4)= 1
