Answer:
ok I will try solve your problem. good luck
Step-by-step explanation:
a. known: Bank balances : 3021 pesos
monthly withdrawals: 78 pesos
months of withdrawal: 12 months
b. asked: new bank balance?
c. equation: New bank balance= bank balance - ( monthly withdrawals X months of withdrawal)
d. New bank balance: 3021- (78x12)
= 3021 - 936
= 2085 pesos
e. my new bank balance is 2085 pesos.
The original equation is x=10×200
Frank and the # of workers hired= # of workers+Frank
x= the total area of the field, not how much each worker has to harvest
10×20=200
9+1=10
10×200=x
Solution: B. Frank and nine workers are hired to harvest tomatoes from a field. If each of the workers is given a plot which is 10 by 20 feet in size,what is the total area of the field?
15 + 8= 23
23/2 = 11.2
-5 + 8 = 3
3/2= 1.5
Answer is (11.2,1.5)
A quadratic equation is an equation whose leading coefficient is of second degree. The time can not be negative, therefore, the time in which the athlete complete the jump is 0.75 seconds.
<h3>What is a quadratic equation?</h3>
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
The jump is represented by the equation h(x)= -16x²+4x+6. The time is represented by x, now the height of the athlete will be zero when the jump will be completed therefore, we can write,
0 = - 16x² + 4x + 6
0 = - 16x² + 12x - 8x + 6
0 = -4x(4x-3) -2(4x-3)
0 = (-4x-2)(4x-3)
x = -0.50, 0.75
Since the time can not be negative, therefore, the time in which the athlete complete the jump is 0.75 seconds.

The sum of the distances of R to Q and P to Q is 9 units.
Solution:
Given points are P(–3, 6), Q(3, 6) and R(3, 3).
Distance between two points formula:

Distance from R to Q:
Here 
Substitute these in the given formula, we get
Distance =

= 3 units
Distance from R to Q is 3 units.
Distance from P to Q:
Here 
Substitute these in the given formula, we get
Distance =

= 6 units
Distance from P to Q is 6 units.
Sum of the distances = 3 + 6 = 9 units
Hence the sum of the distances of R to Q and P to Q is 9 units.
