Answer:
a. x=0
b x=-8
c x=49/2
Step-by-step explanation:
a. x2+4=4
subtract 4 from both sides
x2=0
multiply
2x=0
divide by 2
x=0
b x2 + 16 = 0
multiply
2x+16=0
subtract both sides by 16
2x=-16
divide by 2
x=-8
c x2 − 49 = 0
multiply
2x-49=0
add 49 to both sides
2x=49
divide both sides by 2
x=49/2
Answer:
a. X= 0
b. X= undefined or X=4i
c. X= + or - 7
Step-by-step explanation:
a. x² + 4 = 4
when 4 goes to the other side by negative sign it will cancel the other 4. at they equal in magnitude and opposite in sign.
then x² = 0 , where √x²=√0 , finally x=0
b. x² + 16 = 0
16 goes to other side by negative sign too
x² = -16 , where √x²=√-16 , finally x= undefined
due to the negative sign under thr square root.
at √-1 = i then x can be 4i
c. x² - 49 = 0
-49 go to the other side by positive sign
x² = 49 , where √x² = √49 , finally x= + or - 7
where negative sign is neglected at even power
example:
(-7)²=(7)²

Farmer Janet can plant 9 feet of carrots in 15 minutes while her daughter Amy can plant 17 feet of carrots in half an hour. Which farmer plants carrots more quickly?
Answer:
Farmer Janet can plant carrots more quickly.
Step-by-step explanation:
If we added 15 more minutes to Farmer Janet's time to equal the same amount as her daughter. We would also have to double the amount of carrots she can plant which totals out to 18 carrots which is 1 more carrot more than her daughter. I hope this helps:)

A surfer is riding a 7 foot wave. The angle of depression from the surfer to the shoreline is 10 degrees. What is the distance from the surfer to the shoreline
Step-by-step explanation:
The distance from the surfer to the shoreline will be found as follows:
tan θ= opposite/adjacent
θ=10°
opposite=7ft
adjacent= x ft
substituting the values in our formula and solving for x we get
tan 10=7/x
hence
x=7/tan10
x=39.69897~ 39.7 ft
The surfer is 39.7 ft from the shoreline.
Answer:
The surfer is 39.7 ft from the shoreline.

$35 bill before tax
tax:5.8%
Tip:21%
Answer:
If tip goes only on amount but not on tax: $44.38
If tip goes on total including tax: $44.81
Step-by-step explanation:
If the tip is applied to the price before tax, then we need to add 5.8% and 21% of $35 to $35.
tax + tip = 5.8% + 21% = 26.8%
100% + 26.8% = 126.8% = 1.268
1.268 * $35 = $44.38
If the tip is applied to the price plus tax, then we calculate the amount including tax first, then we add the 21% tip based on that price.
Bill before tax: $35
Add 5.8% tax: 1.058 * $35 = $37.03
Add tip to the amount including tax: 1.21 * $37.03 = $44.81

Jonas has been saving for a video game. Last year it cost $28. This year it cost $36. Find the percent of change in the cost. Round to the nearest whole percent if necessary.
Answer:
28.57%
Step-by-step explanation:
Given data
Initial cost =$28
Final cost =$36
Required
The percentage change in cost
Percent change =final - initial/initial*100
Substitute
Percent change =36-28/28*100
Percent change =8/28*100
Percent change =0. 2857*100
Percent change =28.57%

Step-by-step explanation:
Answer:
f(-2) = 42Step-by-step explanation:
Given function:
f(x) = 2x²−3x + 28Find f(x) when x = -2
f(-2) = 2(-2)² - 3(-2) + 28 = 2(4) + 6 + 28 = 425,25,125 find 10th term
Answer:
9765625
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
r = 25 ÷ 5 = 125 ÷ 25 = 5
This indicates the sequence is geometric with n th term
[tex]a_{n}[/tex] = a₁[tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 5 and r = 5 , then
a₁₀ = 5 × [tex]5^{9}[/tex] = 5 × 1953125 = 9765625

How do you plot an ordered pair on a coordinate plane?
Answer:
(x,y)
Step-by-step explanation:
You do x axis first then y axis
Answer:
coordinates are paired as (x,y) and there are designated lines that are x and y. in order to plot the x value on the horizontal line (side to side) then go up or down however many per y value. if the coordinates are (4,5) then go over 4 positive, and go up 5 positive. if the pair is (-3,-6) then go left to -3, then down to -6. hope this makes sense and helps you ;]
