The slope of a line through the points (-2, 4) and (6, b) is -3/4 What is the value of b?
9514 1404 393
Answer:
-2
Step-by-step explanation:
The slope formula can be used. Fill in the given information and solve for b.
m = (y2 -y1)/(x2 -x1)
-3/4 = (b -4)/(6 -(-2))
-6 = b -4 . . . . . . multiply by 8
-2 = b . . . . . . . . add 4
The value of b is -2.

Answer:
3.7%
Step-by-step explanation:
(p)principal=$3400
(t)time=9months=9÷12year=3÷4year
(i)interest=$94.50
(r)rate=?
we have
r%=i/(pt)
r%=94.50÷(3400×3÷4)
r÷100=94.50÷2550
r=0.37×100
r=3.7
required rate is 3/7%

A pair of tow trucks are pulling on a trailer that is stuck
in mud. The first truck pulls a a pair of tow trucks are pulling on a trailer that is stuck in mud. the first truck pulls with a force of 10,000
pounds at a 110° angle from the second truck, which is
pulling with a force of 7,500 pounds. What is the
magnitude of the resultant force?
9.821 pounds
10,244 pounds
14,405 pounds
24 226 pounds
Answer:
R=10,244 Lb
Step-by-step explanation:
In order to solve this problem, we can start by drawing the situation. (See attached picture).
We can look at the forces applied by the trucks as vectors, so in this case, in order to find the resultant force, we can add the two vectors. You can do so by drawing one force after the other and join the start of the first force with the end of the second force to form a triangle. The missing side will be the resultant force. In that triangle I drew there, the inner angle will be found by subtracting 180°-110°=70°
In this case we can find the resultant force by using the law of cosines:
[tex]A^{2}=B^{2}+C^{2}-2AB cos \alpha[/tex]
so we can use the data given by the problem:
[tex]R^{2}=T_{1}^{2}+T_{2}^{2}-2T_{1}T_{2} cos \alpha[/tex]
so we can solve this for R, so we get:
[tex]R=\sqrt{T_{1}^{2}+T_{2}^{2}-2T_{1}T_{2} cos \alpha}[/tex]
now we can substitute:
[tex]R=\sqrt{(10,000Lb)^{2}+(7,500Lb)^{2}-2(10,000Lb)(7,500Lb) cos (70^{0})}[/tex]
which yields:
R=10,244Lb

He shuffles the deck and selects one card and then another. In its simplest form, what is the probability that he draws a pair of tens?
Answer:
Step-by-step explanation:
Probability of getting pair of 10's: 1/221
We have the following information available from the question is:
There are four suits with 13 cards in each from ace through to king.
Two cards one after another are drawn from a deck of 52 cards.
We have to find the probability that he draws a pair of tens.
Now, According to the question:
We know that:
In a pack of 52 cards, there is 4 tens:
Then, Probability of getting 10 in first attempt:
= 4/52
After drawn first ten, There is 51 cards are remaining in a pack of cards and no. of ten's = 3
Probability of getting 10 in 2nd attempt :
= 3/51
Probability of getting pair of 10's:
[tex]=\frac{4}{52} (\frac{3}{51} )=\frac{12}{2652}[/tex]

Question 5 (5 points)
(04.05 MC)
Which graph best represents the function f(x) = 4(1.5)x? (5 points)
Question 5 options:
1)
graph of increasing exponential function going through point 0, 2
2)
graph of increasing exponential function going through point 0, 3
3)
graph of increasing exponential function going through point 0, 1
4)
graph of increasing exponential function going through point 0, 4
Answer:
I am guessing the equation you meant to type is [tex]f(x)=4(1.5)^x[/tex]. Based on this information, I know that the answer is:
4) Graph of increasing exponential function going through point (0, 4).
Step-by-step explanation:
I graphed the function in Desmos, and I found that the y-intercept is (0,4). Answer choices 1-3 all have varying y-intercept options, while option number 4 says the graph is going through point (0,4) so we know that's the right answer.
I hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and good luck with the rest of your assignment. I'll attach a photo of the graph below, so you understand the graph.
Answer:
I had the same exact problem on my quiz! The answer is D, because the y intercept is (0,4). Graphing the equation really helped me understand it! :)

131 is the weight of the lightest person in the group.
If we look closely the stem has the 13 as the lowest number. And corresponding to it the least number is 1.
Therefore the lightest weight person is 131 .All other weights are greater than 131 e.g 132 , 134 and 136 .
The data shows there are 131 ,131, 132,132,134,134, and 136 weights in the least weight group. So out of these 131 is the smallest.

Martina has a circle with a diameter
of 6 inches. She doubled the
diameter to make a new circle.
Now, Martina says that the ratio of
the circle's circumference to its
diameter has also doubled. Correct
her mistake.
Answer:
The ratio of the circumference to its diameter remains the same.
Step-by-step explanation:
Given,
diameter of circle = 6 inch
diameter is doubled.
New diameter of circle = 2 x 6 = 12 inch
We know that,
The Circumference of a circle is 2 π r or π d where r is the radius of the circle and d is the diameter of the circle.
Circumference of the circle when the diameter is 6 inches.
C₁ = 6π
Ratio of circumference to diameter
Ratio = [tex]\dfrac{6\pi}{6}[/tex]
Ratio = π
When the diameter is 12 inches
C₂ = 12 π
Ratio of circumference to diameter
Ratio = [tex]\dfrac{12\pi}{12}[/tex]
Ratio = π
Now, the correct statement is the ratio of the circumference to its diameter remains the same if the diameter is doubled.
