Find the equation of the normal to the curve in y=mx+b format : p(t) = 3t^2 - 8t + 3 at t = 3
Answers
Answer:
[tex]y=10x+24[/tex]
Step-by-step explanation:
Find the derivative of the function
[tex]p'(t)=\frac{d[p(t)]}{dt}=\frac{d}{dt}(3t^2-8t+3)=6t-8[/tex]
Determine the slope of p(t) at t=3:
[tex]p'(3)=6(3)-8=18-8=10[/tex]
Find p(3):
[tex]p(3)=3(3)^2-8(3)+3=3(9)-24+3=27-21=6[/tex]
Determine y-intercept:
[tex]y=mx+b[/tex]
[tex]6=10(3)+b[/tex]
[tex]6=30+b[/tex]
[tex]-24=b[/tex]
Final equation:
[tex]y=10x-24[/tex]

103 +14 =117
180 - 117= 63
then to find which sides were the longest I looked and the angles and found their corresponding sides.
<D went with side FE
<F went with side DE
<E went with side FD
The smallest angle was <E therefore the smallest side was FD
The middle angle was <F therefore the medium side was DE
The largest angle was <D therefore the smallest side was FE

1) 6 balls
Step-by-step explanation:
x = number of balls Elsa can shoot
x + 6 = number of balls Anna can shoot
18 = number of balls together they can shoot
x + (x + 6) = 18
x + x + 6 = 18
2x + 6 = 18
2x = 18 - 6
2x = 12
x = 6

Let us say x=7
Then 9*7+7y =180
7y =180–63 = 117
y =117/7=19.2 this will not do as it contains decimal not whole number
Say x=6
Then 9*6 +7y =180
7y=180–54 =126
y =126/7 =18 this is acceptable as it is whole number

Work out the percentage change to 2 decimal places when a price of £60 is increased to £89.99.
Answers
Answer:
49.98%
Step-by-step explanation:
Original price: £60
New price: £89.99
The difference in prices: £89.99 - £60 = £29.99
£60 - 100% (the original price)
£29.99 - x (the % that we want to calculate)
29.99 × 100 = 2999
2999 ÷ 60 = 49,9833333

Answer:
-3; (8, -20)
Step-by-step explanation:
to find the rate of change we do (y2 - y1) / (x2 - x1)
basically we choose 2 points on y and subtract them while using the 2 points on x and subtracting them
after subtracting them we divide change of y by change of x
for this one i chose (3, -5) and (6, -14)
-14 - (-5) = -9
6 - 3 = 3
-9 / 3 = -3
the rate of change is three
to find the y intercept we can use this equation
y = -3x + b
and then plug in things
ill plug in the first set of coordinates
-5 = -3(3) + b
-5 = -9 + b
b = 4
so the y intercept is b
using this equation
y = -3x + 4
we can find out what value y is when the x value is 8
-3(8) + 4 = -20

Melinda creates jewelry. After purchasing supplies, she had $150 left in her account. She sells five bracelets and a necklace making her new account total $235. If the necklace sold for $22. 50, which equation can be used to determine the sales price of the bracelets?.
Answers
The equation that can be used to determine the sales price of the bracelets is $22.5
Amount in her account = $150
Amount in her account after sales = $235
Change in account balance = $235 - $150
= $85
cost of necklace = $22.5
let
bracelet = x
necklace = y
The equation:
Total sales = 5x + y
85 = 5x + 22.5
85 - 22.5 = 5x
62.5 = 5x
x = 62.5/5
x = $12.5
Therefore, the cost of each bracelet is $12.5 and the cost of necklace is $22.5
