The coordinates of the vertices of triangle QRS are Q (1,-2), R (1,9),
S (6,-4). What is the length, in units, of the line segment that connects
vertex Q to vertex R?
I think 1700000000000000000
Answer:
QR = 11
Step-by-step explanation:
Q and R are on a vertical line. Therefore, QR = 9 - (-2) = 9 + 2 = 11
juanita makes leather lanyards to sell she charges a base fee and a cost per inch of the finished lanyard. the line shows the cost y for x inches of lanyard
Complete Question:
Juanita makes leather lanyards to sell. She
charges a base fee and a cost per inch of
the finished lanyard. The line shows the
cost y for x inches of lanyard. Write an
equation for the line in slope-intercept
form.
*See attachement for the graph given
Answer:
y = ½x + 5
Step-by-step explanation:
Equation in slope-intercept takes the following form, y = mx + b
m = slope = change in y/change in x
b = y-intercept
Let's find m and b using the graph given
✔️Slope of the line using two points form the graph, say (0, 5) and (2, 6):
Slope (m) = ∆y/∆x = (6 - 5)/(2 - 0) = 1/2
Slope (m) = ½
✔️ y-intercept (b) is the y-coordinate of the point where the line intercepts the y-axis = 5. When y = 5, x = 0. Therefore,
b = 5
✔️To write the equation of the line, substitute m = ½ and b = 5 into y = mx + b:
y = ½x + 5
Asif wants to open a lemonade stand during a town fair. He buys a pitcher and lemonade concentrate from a store for this purpose. At the lemonade stand, the cost for each cup of lemonade will be the same. If Asif sells 32 cups of lemonade, he will have a profit of $0. If he sells 45 cups of lemonade, he will have a profit of $16.25.
Complete question
Asif wants to open a lemonade stand during a town fair. He buys a pitcher and lemonade concentrate from a store for this purpose. At the lemonade stand, the cost for each cup of lemonade will be the same. If Asif sells 32 cups of lemonade, he will have a profit of $0. If he sells 45 cups of lemonade, he will have a profit of $16.25. Determine the rate of change for a function that represents Asif's profit, y, in dollars, from selling x cups of lemonade.
Answer:
Step-by-step explanation:
The rate of Change for the function that determines profit :
Slope value, m ;
Slope, m = Rise / Run = (y2-y1) / (x2 - x1)
y2 = 16.25 ; y1= 0 ; x2 = 45 ; x1 = 32
m = (16.25 - 0) / (45 - 32)
m = 16.25 / 13
m = 1.25
Hence, the rate of change in in profit for selling x k cuos of lemonade = $1.25

If Z is the centroid of RST, RZ = 42, ST = 74, TW = 51, ZY = 23 and find each measure TZ = ? ZW = ? SY = ? XZ = ?
The Triangle RST is missing, so i have attached it.
Answer:
A) TZ = 34
B) ZW = 17
C) SY = 69
D) XZ = 21
Step-by-step explanation:
To form the centroid, we see median drawn from the centre of all three sides.
Thus means the 3 sides are divided into 2 and as such;
XS = XT
YR = YT
WR = WT
Now, for median that forms centroid, the two parts are usually not the same length but instead in the ratio 2:1. That means one portion of the line segment is twice the length of the other.
Thus, by inspection of the given triangle, we can say that;
SZ = 2(ZY)
TZ = 2(ZW)
RZ = 2(XZ)
A) Now, we are given TW = 51
TW is made up of TZ and ZW
But since TZ : ZW = 2:1, it means that;
TZ = ⅔ × TW
TZ = ⅔ × 51
TZ = 34
B) From earlier, we saw that TZ = 2(ZW).
Thus; 34 = 2(ZW)
ZW = 34/2
ZW = 17
C) We are given ZY = 23.
From earlier, we saw that;SZ = 2(ZY)
Thus; SZ = 2(23)
SZ = 46
From the attached image we can see that;
SY = SZ + ZY
Thus;
SY = 46 + 23
SY = 69
D) We are given RZ = 42.
From earlier, we saw that;
RZ = 2(XZ)
Thus;
42 = 2(XZ)
XZ = 42/2
XZ = 21

The height of a triangle is 2 less than 5 times its base. If the base of the triangle is x feet, and the area of the triangle is 12 square feet, which equation models this situation?
Answer:
12 = 1/2(x)(5x - 2)
Bonus solution for x = 2.4 ft
Step-by-step explanation:
area = 1/2xh
h = 5x - 2
12 = 1/2(x)(5x - 2)
24 = 5x² - 2x
5x² - 2x - 24 = 0
x² - 0.4x - 4.8 = 0
(x - 2.4)(x + 2) = 0
x = 2.4
Answer:
5x^2 − 2x − 24 = 0

Hailey went hiking she started the hike at the elevation of 243 feet she climbed down 782 feet when she was ready to leave she climbed back up 118 feet what was haileys elevation at the end of the hiking trip
Answer:
-421 feet
Step-by-step explanation:
If she started at 243 feet, subtract 782 feet which is -539 feet. Then add 118 feet which is -421 feet. This is how my sister did it so I hope it helps!
Let f(-x) = 5x – 2 and g(x) = 2x + 3 and find f(x) –
f(0) — 9(x) = 7x – 1
f(.2) – 9(x) = 7x + 1
f(x) — 9(2) = 3x – 5
f(x) – 9(x) = -3x +5
Answer:
3x - 5
Step-by-step explanation:
Given that f(x) = 5x - 2 and g(x) = 2x+3
f(x) - g(x) = 5x-2 - (2x+3)
Expand
f(x) - g(x) = 5x - 2 - 2x - 3
Collect like terms
f(x) - g(x) = 5x - 2x -2-3
f(x) - g(x) = 3x - 5
Hence the required answer is 3x - 5

Answer:
-85
Step-by-step explanation:
We are given the equation [tex]E^8_{n=1}[/tex][tex](-2)^{n-1}[/tex] and are asked to evaluate it.
This can be solved using the geometric sequence, but first we have to determine our "r", "n", and [tex]a_{1}[/tex].
Of course [tex]a_{1}[/tex] is equal to 1. Therefore,
[tex]a_{1[/tex] = 1
[tex]r=[/tex]
[tex]n=[/tex]
(-2) is the change per number in the sequence, therefore -2 is our "r".
[tex]a_{1[/tex] = 1
[tex]r=-2[/tex]
[tex]n=[/tex]
The number "8" on [tex]E^8_{n-1}[/tex] represents the "n". Therefore 8 is our "n".
[tex]a_{1}=1[/tex]
[tex]r=-2[/tex]
[tex]n=8[/tex]
Use the geometric sequence sum formula and substitute :
[tex]a_{1} \frac{1-r^n}{1-r}[/tex]
[tex]1* \frac{1-(-2)^8}{1-(-2)}[/tex]
[tex]1* \frac{1-(-2)^8}{1+2}[/tex]
[tex]1* \frac{1-256}{1+2}[/tex]
[tex]1* \frac{-255}{3}[/tex]
[tex]1 * -85[/tex]
[tex]-85[/tex]

The height of the rectangular prism measures 64 cm. If the height is increased by 1.5 cm, by how much will the surface area of the box increase?
Answer:
Increase in surface area = 126 cm²
Step-by-step explanation:
Surface area of the rectangular prism has the dimensions as
Length = 42 cm
Width = 35 cm
Height = 64 cm
Total surface area of the rectangular prism = 2(lb + bh + hl)
Here, l = Length of the box
b = Width of rectangular box
h = height
Total surface area = 2(42×35 + 35×64 + 64×42)
= 2(1470 + 2240 + 2688)
= 12796 cm²
If height is increased by by 1.5 cm, new height of the box = 64 + 1.5 = 65.5 cm
Surface area of the box = 2(42×35 + 35×65.5 + 65.5×42)
= 2(1470 + 2240 + 2751)
= 12922 cm²
Increase in surface area = 12922 - 12796
= 126 cm²

Answer:
177 ft below sea level
Step-by-step explanation:
282
10 x 12 = 120. This represents how man ft the hot air balloon rose.
282 - 120 = 162. Keep in mind your still below sea level.
162 + 15 = 177
You add 15 because the hot air balloon is going down 15 feet which adds to being below sea level. ( Your going deeper/lower)
