Step-by-step explanation:
given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
• if a > 0 then parabola opens upwards
• if a < 0 then parabola opens downwards
given
y = 5x² - 17x - 12
with a = 5 > 0
then parabola opens upward
there are 58 total views for the month.
Bookface averaged 24.3 views more than Snapgram. Giggle averaged 14.6 less views than Bookface.
Find how many views each site got during the month.
PLEASE ASAP THIS IS DUE TODAY! Thank you!
The number of views snapgram, bookface and giggle have are 8, 32.3, 17.7 views respectively.
How to solve equationTotal views = 58let
snapgram views = xBookface views = x + 24.3Giggle views = (x + 24.3) - 14.6= x + 24.3 - 14.6
= x + 9.7
Total = snapgram + bookface + giggle
58 = x + (x + 24.3) + (x + 9.7)
58 = x + x + 24.3 + x + 9.7
58 = 3x + 33
3x = 58 - 34
3x = 24
x = 24/3
x = 8 views
Therefore,
snapgram views = x
= 8 views
Bookface views = x + 24.3
= 8 + 24.3
= 32.3 views
Giggle views = x + 9.7
= 8 + 9.7
= 17.7 views

A parasail rider wants to reach the maximum height allowed by the Federal Aviation Administration if the rider's boat is to tow the parachute at 30 miles per hour, how long should the tow line be to reach the maximum flying height? a. Draw and label a diagram to represent this situation. PLEASE HELP
From the information given, the towline must be completely released to enable it to get to the maximum height. This problem is a trigonometry problem because it involves a solution that looks like a right-angled triangle.
How else can the maximum height of the parasailer be identified?In order to determine the maximum height of the parasailer, the length of the rope or towline must be established.
If the length and the height are known, the angle of elevation can be determined using the SOHCAHTOA rule.
SOH - Sine is Opposite over Hypotenuse
CAH - Cosine is Adjacent Over Hypotenus; while
TOA - Tangent is Opposite over Adjacent.

What is ratio of two numbers?
The ratio of two number is the fraction part, which represent that how a number is more or less compare to the other.
There are two tables which give the number of pints of blue and yellow that are used to make different amounts of two shades of green dye. The table is given below;
Green #1 is made by mixing blue and yellow in a ratio of 2 : 3.Green #2 is made by mixing blue and yellow in a ratio of 1 : 2.The first one has 2 parts of blue at 3 parts of yellow. In the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2.
In grade two the blue part is half of the yellow part. This means that green #1 is bluer shade of green than Green # 2.
Hence, in the two highlighted rows show that for the same amount of yellow, Green #1 uses more blue than Green #2 and green #1 is bluer shade of green than Green # 2.

Answer:
Lesser x = -14
Greater x = 0
Step-by-step explanation:
Given equation:
[tex]\sf (x+7)^2-49=0[/tex]
Add 49 to both sides:
[tex]\implies \sf (x+7)^2-49+49=0+49[/tex]
[tex]\implies \sf (x+7)^2=49[/tex]
Square root both sides:
[tex]\implies \sf \sqrt{(x+7)^2}=\sqrt{49}[/tex]
[tex]\implies \sf x+7=\pm7[/tex]
Solve for x:

find the value of cos θ if sin θ=1/2;0 degrees< θ< 90 degrees
Answer:
cosΘ = [tex]\frac{\sqrt{3} }{2}[/tex]
Step-by-step explanation:
sin²Θ + cos²Θ = 1 ( subtract sin²Θ from both sides )
cos²Θ = 1 - sin²Θ ( take square root of both sides )
cosΘ = ± [tex]\sqrt{1-sin^20}[/tex]
= ± [tex]\sqrt{1-(\frac{1}{2})^2 }[/tex]
= ± [tex]\sqrt{1-\frac{1}{4} }[/tex]
= ± [tex]\sqrt{\frac{3}{4} }[/tex]
= ± [tex]\frac{\sqrt{3} }{2}[/tex]
since 0° < Θ < 90° , then
cosΘ = [tex]\frac{\sqrt{3} }{2}[/tex]
A rectangular banner has a perimeter of 192 inches and a length of 60 inches.
What is the width of the banner? please answer!
width= area /length
width= 192/60
Width= 3.2 inches
Answer:
36 is the width.
Step-by-step explanation:
A rectangle has four sides.
So the equation should be:
60+60+?+?= 192.
In order to cancel out the two 60s, you subtract it from 192.
So,
?+?=72.
The sides opposite of a rectangle is congruent, thus,
72/2=36.
The width of the rectangular banner is 36, and to check the answer you just plug all the digits in.
60+60+36+36=192.

126 square yards
Step-by-step explanation:
So first you want to use this formula:
2(L×W) + 2(L×H) +2(W×H)
Then plug it in:
2(6×5) + 2(6×3) + 2(5×3)
Next you solve:
6×5 = 30×2 = 60
6×3 = 18×2 = 36
5×3 = 15×2 = 30
After this you add them all up:
60 + 36 + 30 = 126
So you answer is 126 square yards

what is the absolute value of |4.7|

Step-by-step explanation:
Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified line, using the disk/washer method. Sketch the region, the solid, and a typical disk or washer.y = (x - 2)^2 ; y=2x-1 ; about the line y = -1
Check the picture below.
to check where the functions intersect, we can simply set them equal to each other so (x-2)² = 2x - 1, anyhow, not to bore you to death with that, it's as the picture shows it, at x = 1 and x = 5, so those are our bounds.
to get the R² part of the washer, what I do is using the "area under the curve" method of f(x) - g(x), where g(x) is the axis of rotation and f(x) is the farthest radius, so to get R² I'd process (x-2)² - (-1), that'd give me R and then I'd square that.
to get r², I do pretty much the same thing, f(x) - g(x) where g(x) is the axis of rotation and f(x) is the closest radius, in this namely (2x - 1) - (-1), and that'd give "r" and then we can square that to get r².
