39.
-3^ - 2(-5)(3)
-3*-3= 9
2*-5*3 = -30
9 - (-30)
subtracting a negative really means add.
9 + 30 = 39

Sydney invested $440 in an account paying an interest rate of 5.6% compounded daily. Assuming no deposits or withdrawals are mad
stealth61 [152]

Answer:

The time required to get  a total amount of $ 640.00  from compound interest on a principal of $ 440.00  at an interest rate of 5.6% per year  and compounded 365 times per year  is approximately 7 years.

Step-by-step explanation:

Given

  • Principle Amount P = $440
  • Accrued Amount A = $640
  • Interest rate r = 5.6% = 0.056
  • Compounded daily n = 365

To determine:

Time period t = ?

Using the formula

A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}

solving for t

t = ln(A/P) / n[ln(1 + r/n)]

substituting the values A = 640, P = 440, n = 365 and r = 0.056

t = ln(640/440) / ( 365 × [ln(1 + 0.00015342465753425/365)] )

t = 6.691

t ≈ 7  (nearest year)

Therefore, the time required to get  a total amount of $ 640.00  from compound interest on a principal of $ 440.00  at an interest rate of 5.6% per year  and compounded 365 times per year  is approximately 7 years.

Will someone pls mind helping me with these math problems ill mean a lot to me or at least just look at it
Vinvika [58]

Answer:

Step-by-step explanation:

Mathematics is a necessary skill that people use throughout their lives, such as when they travel, use money, or keep track of time. Therefore, mathematics is an important skill to learn at school. Unfortunately, many children and adults feel stressed and anxious when they have to do math. People who experience feelings of stress when faced with math-related situations may be experiencing what is called “math anxiety.” Math anxiety affects many people and is related to poor math ability in school and later during adulthood. Researchers have studied how math anxiety first appears, what is happening in the brain when people experience math anxiety, and how to best help people who are suffering with math anxiety.Researchers are also interested in how math anxiety develops. Although research has shown that math anxiety and math abilities are related [1], no study so far has been able to tell us which comes first. In other words, we do not know if being bad at math causes math anxiety, or if having math anxiety makes people bad at math.

Researchers have two ideas about how math anxiety might develop. One idea is that children who struggle with learning numbers when they are very young are more likely to develop math anxiety when they start going to school. This idea has not yet been tested in children. Another idea is that math anxiety develops in children who experience certain kinds of social situations that influence the child’s thoughts or feelings. This means that the child’s emotions, opinions, or behaviors are affected by things that other people say or do. 7/6
