Answer:
x < - 4/5
Step-by-step explanation:
Given the inequality:
4x +4< 9x +8
Collect like terms :
4x - 9x < 8 - 4
-5x < 4
Divide both sides by - 5
-5x / - 5 < 4 / - 5
x < - 4/5
Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $12,110?
Answer:
17
Step-by-step explanation:
Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. It takes 17 year for the value of the account to reach $12,110.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =P(1+r/n)^rt
Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. for the value of the account to reach $12,110 we need to find the time it takes.
The principal amount = $7,200
Rate = 3.1%
Compound Interest = [tex]P(1+r/n)^{rt}[/tex]
12,110 = [tex]7200(1+3.1/12)^{3.1t}[/tex]
t = 17
Thus, for the value of the account to reach $12,110 the time taken is 17.

Answer:
The sum of the first 6 terms of the inifinite series is -21.
Step-by-step explanation:
Following the sequence, we can see that each term is the previous term multiplied by -2. So, the first six terms are:

Solve the system of equations.
Answer:
x =-5 and y = -6
Step-by-step explanation:
In order to get the answer, I used the elimination/addition method
8y-9x= -3 <— I decided to eliminate the y
5y-8x= 10 <— I decided to eliminate the y
5(8y-9x = -3) <— switch up the number of y from the bottom to multiply
-8(5y-8x= 10) <— switch up the number of y from the top to multiply, but have a negative sign to it
So...our new equation will be....
40y - 45x = -15
+ -40y + 64x = -80
________________________
19x = -95
x = -5
8y-9x= -3
8y-9(-5) = -3
8y+45 = -3
- 45 = - 45
8y = -48
y = -6

If the standard deviation of shear strength measurements for spot welds is 9.5 pounds per square inch (psi), what is the minimum number of test welds that should be sampled if we want the sample mean to be within 1.4 psi of the true mean with probability approximately 0.99
Answer: 306
Step-by-step explanation:
Formula to find sample size:
[tex]n=(\dfrac{\sigma\times z^*}{E})^2[/tex] , where [tex]\sigma[/tex] = standard deviation, E = margin of error, z* = critrical z-value.
As per given,
[tex]\sigma=9.5 , E=1.4[/tex]
Critical z-value for 99% confidence = 2.576
Now , the minimum sampl size :[tex]n=(\dfrac{9.5\times2.576}{1.4})^2[/tex]
[tex]\Rightarrow\ n=305.5504\approx306[/tex]
Hence, the required sample size = 306

Answer:
WY = 28
Step-by-step explanation:
Using the pythagorean theorem, we can find out the measures of lenghts WX and YX individually.
VX^2 = VW^2 + WX^2
ZX^2 = ZX^2 + XY^2
Substitute
400 = 256 + WX^2
400 = 144 + XY^2
Simplify
WX^2 = 144
XY^2 = 256
WX = 12
XY = 16
WY = 28

A plane flying at an altitude of 4 miles is approaching an airport that is 31 miles ahead on
the pilot's line of sight. What is the angle of depression from the plane to the airport to the
nearest TENTH of a degree?
Answer:
[tex]7.4^{o}[/tex]
Step-by-step explanation:
Altitude of the plane = 4 miles
Distance from the plane to the airport = 31 miles
Let the angle of depression from the plane to the airport be represented by θ. Thus applying the appropriate trigonometric function, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
= [tex]\frac{4}{31}[/tex]
= 0.1290
θ = [tex]Tan^{-1}[/tex] 0.1290
= 7.3506
θ = [tex]7.4^{o}[/tex]
The angle of depression from the plane to the airport is [tex]7.4^{o}[/tex].
