If $800 is deposited into a new savings account with a simple interest rate of 1.8%, what will be the total amount in the account after 15 years?
Answer:
Step-by-step explanation:
I = prt
I = 800 × 1.8% x 15
I = $216
Remember the percent sign for the rate or write it as a decimal (multiplier)! In this case the multiplier would be 0.018!

Pekka tosses a ball out of a window that is 40 feet in the air. Its initial velocity is 15
feet per second. The path of the ball is represented by
h = -16t2 + 15t + 40
How long does it take for the ball to hit the ground (in seconds) rounded to the
nearest hundredth?
Answer:
2.12 seconds
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 15t + 40[/tex]
Required
Determine how long the ball hits the ground
When the ball hits the ground means that [tex]h(t) = 0[/tex]
So, we have that:
[tex]h(t) = -16t^2 + 15t + 40[/tex] becomes
[tex]0 = -16t^2 + 15t + 40[/tex]
Reorder
[tex]-16t^2 + 15t + 40 = 0[/tex]
Multiply through by -1
[tex]16t^2 - 15t - 40 = 0[/tex]
Solve using quadratic:
[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 16[/tex] [tex]b = -15[/tex] [tex]c = -40[/tex]
So, we have:
[tex]t = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}[/tex] becomes
[tex]t = \frac{-(-15)\±\sqrt{(-15)^2 - 4*16*-40}}{2*16}[/tex]
[tex]t = \frac{15\±\sqrt{(-15)^2 - 4*16*-40}}{2*16}[/tex]
[tex]t = \frac{15\±\sqrt{225 +2560}}{32}[/tex]
[tex]t = \frac{15\±\sqrt{2785}}{32}[/tex]
[tex]t = \frac{15\±52.77}{32}[/tex]
Split:
[tex]t = \frac{15+52.77}{32}[/tex] or [tex]t = \frac{15-52.77}{32}[/tex]
[tex]t = \frac{67.77}{32}[/tex] or [tex]t = \frac{-37.77}{32}[/tex]
[tex]t = 2.12[/tex] or [tex]t = -1.18[/tex]
But time can't be negative
So:
[tex]t = 2.12[/tex]
Hence, time to hit the ground is 2.12 seconds

what is the equation of a line that passes through (4,6) and is parallel to y=2x+2 ?
Answer:
y=2x-2
Step-by-step explanation:
my work is in the picture I attached. lmk if you'd like me to explain more
Answer:
y = 2x - 2
Step-by-step explanation:
let equation of the line be y = mx + c
since it is parallel to y = 2x + 2, gradient/slope of the two lines would be the same
therefore, m = 2
since it passes through (4, 6),
sub (4, 6):
6 = 2(4) + c
c = -2
therefore equation of the line is y = 2x - 2
The points (20, 80) and (30, 120) form a proportional relationship. What is the slope of the line that passes through these points?
Plz help me, I am terrible in math
Answer: it is either C or D
Step-by-step explanation:but It looks like its D
I need help please
Answer:
false
Step-by-step explanation:
Answer:
False, it has no solution if the lines are parallel.
Write the equation in slope-intercept form. Then identify the slope and the y-intercept.
6x + 2y = 10
Slope formula - y = mx + b
6x + 2y = 10
subtract x
2y = 10 - 6x
divide all by 2
y = 5 - 3x
y = -3x + 5
5 is the y-intercept, and -3x is the slope
hope this helps :)

The graph of g(x) is the result of translating the graph of f(x) = 3x six units to the right. What is the equation of g(x)?
g(x) = 3x – 6
g(x) = 3x + 6
g(x) = 3x – 6
g(x) = 3x + 6

Answer:
a
Step-by-step explanation:
solve for the indicated information. solve for x.
Answer:
-9
Step-by-step explanation:
x + 109 + x + 89 = 180° because these angles are supplementary
2x + 198 = 180 subtract 198 from both sides
2x = - 18 divide by 2
x = -9

On Friday Simon ate three tenths of a kg of cherries. On Saturday, he ate half of a kg of cherries. What amount of cherries are left now if he had one kg of cherries
Answer:
1/5 kgStep-by-step explanation:
Initial amount = 1 kgEaten on Friday = 3/10 kgEaten on Saturday = 1/2 kgAmount of cherries left:
1 - (3/10 + 1/2) = 1 - (3/10 + 5/10) = 1 - 8/10 = 2/10 = 1/5 kgWhich property is used in the following expression ? (a x b) x c = a x (b x c)

Well, hello! I need help with both of these questions. If you can help me, P l e a s e do! Billy collected 256 conks but lost ¾ of them on his way to school through a hole in his bag. When he arrived at school how many conks did Billy had left? Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?
Answer: 64 ; $28
Step-by-step explanation:
A. Billy collected 256 conks but lost ¾ of them on his way to school through a hole in his bag. When he arrived at school how many conks did Billy had left?
Number of conks collected by Billy = 256
Fraction lost = 3/4
Amount lost = 3/4 × 256 = 192
Number of conks Billy has left will be:
= 256 - 192
= 64
B. Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?
This will cost:
= 7/9 × $36
= 7 × $4
= $28
Your family is having fried rice for dinner. Your mom asks you to divide the 3 bowls of rice so everyone gets an equal amount. How many servings of size 12 can you make out of the 3 bowls of rice?
Answer:
1/4 equal pieces
Step-by-step explanation:
Total number of bowls of rice = 3
We are seeking servings of size 12
Then it means we are dividing 3bowls into 12 equal pieces
= 3/12 bowls
= 1/4 equal pieces
Which means each member of the family is getting 1/4 each of the bowl of rice
Therefore, 1/4 servings of size 12 can you make out of the 3 bowls of rice

PLZ ANSWER GUYS. The sum of 3 consecutive odd numbers is 39. What is the smallest of these numbers? Write an equation for for this problem.
Answer:
The three integers are
11, 13, and 15.
Step-by-step explanation:
. The sum of these is 39, so we can write:
x+(x+2)+(x+4)=39
Open the brackets and simplify.
x+x+2+x=+4=39
3x+6=39
Subtract 6 from each side.
3x=33
Divide both sides by 3.
x=11
Therefore: (x+2)=13 and (x+4)=15

Answer:
y-6=-6(x-1)
Step-by-step explanation:
Hope this helps :D
have a nice thanksgiving
Answer:
[tex]y-6=-6(x-1)[/tex]
Step-by-step explanation:
A point-slope equation requires two values in order to write it: one coordinate and the slope.
First, find the slope between the two given points. To find the slope, you would subtract the first Y from the second Y and the first X from the second X. Y goes on top of the fraction bar, making the equation look like this:
[tex]\frac{6-(-6)}{1-3}[/tex]
Then, simplify the slope equation:
[tex]\frac{6-(-6)}{1-3} = \frac{6+6}{1-3} = \frac{12}{-2} = -6[/tex]
The slope is -6.
Finally, choose one of the coordinates. For this, I'll pick (1, 6).
The point-slope equation is [tex]y-y_{1} =m(x-x_{1})[/tex]
So, simply fill in the [tex]m[/tex], [tex]y_{1}[/tex] , and [tex]x_{1}[/tex] spots with the value we have found.
[tex]m[/tex] is the slope, so replace it with -6.
[tex]y_{1}[/tex] = 6
[tex]x_{1}[/tex] = 1
Final answer:
[tex]y-6=-6(x-1)[/tex]
