Answer:
1,73205
Step-by-step explanation:
First, count out the five decimal places, and then look at the sixth place:
[tex]\sqrt{3}[/tex] ≈ 1,73205 | 0807...
The sixth decimal is less than 5, so we round to the smaller side.

Which graph represents an exponential growth function?
Answer:
Graph 1 or A
Step-by-step explanation:
The graph is gradually getting bigger as it starts at the left (0,-10) and gets bigger and bigger until it hits the end of the chart, increasing endlessly. That is exponential growth.
Diane looked out the window in the store parking lot and said, “There are 13 motorcycles and cars in the lot.” Steve looked out the window and said, “I see 42 wheels.”
Question: How many motorcycles and how many cars are in the parking lot?
Answer:
There are 5 motorcycles and 8 cars in the parking lot.
Step-by-step explanation:
Set variables X to represent the number of cars and Y to represent the number of motorcycles. You will get the following equations:
X + Y = 13 (Total number of motorcycles and cars)
4X + 2Y = 42 (Total number of wheels)
Combine the two equations together and solve for Y and X
4(13 - Y) + 2Y = 42 note: X = 13 - Y
52 - 4Y + 2Y = 42
-2Y = -10
Y = 5
X + 5 = 13
X = 8
the sum of the three terms consecutive terms of an ap is -6 and the product is 64, find the terms. using a, a + d, a + 2d
Answer:
-8, -2 and 4
Step-by-step explanation:
Let the terms of the AP be a-d, a and a+d
If the sum is 6, then;
a-d+a+a+d = -6
3a = -6
a = -6/3
a = -2
Hence the first term is 6
If the product is 64
(a-d)(a)(a+d) = 64
-2(a²-d²) = 64
-2(4-d²) = 64
4-d² = -64/2
4-d² = -32
-d² = -32-4
-d² = -36
d² = 36
d = 6 or -6
The first term is a-d = -2-6 = -8
second term is a = -2
third term is a+d = -2+6 = 4
Hence the required AP is -8, -2 and 4
a student has a savings account with $475 in in it. She deposits $125 of her paycheck into the account every week. Her goal is to save 7,000 for college. How long will it take her to reach her goal of $7000?
Answer:
52.2 weeks
Step-by-step explanation:
7000 - 475 = 6,525
6525 ÷ 125 = 52.2
Answer:
It will take her 53 weeks to get her goal of 7,000$
Step-by-step explanation:
I subtracted 475 from 7,000 to see how much she needed to save for. I got 6525. I multiplied 125 times 52 and got 6500. To get to her goal she needs 25 more dollars so, she'll have to work another week to get to that goal.

X, Y and Z form the vertices of a triangle with area 59.7cm2. If XZ = 21.5cm and XY = 13.5cm, work out the acute angle ∠YXZ. Round to 1 DP.
Answer: The acute angle ∠YXZ = 24.3°.
Step-by-step explanation:
If in triangle ABC, C is the angle included between sides a and b then
Area of triangle = [tex]\dfrac12a\cdot b\cdot sin C[/tex]
here, XZ = 21.5cm and XY = 13.5cm are sides that includes acute angle ∠YXZ..
Area of a triangle = 59.7cm²
then, as per given, we have
[tex]59.7=\dfrac12(21.5)(13.5)\ \sin X\\\\\Rightarrow\ 59.7=145.125\ \sin X\\\\\Rightarrow\ \sin X = \dfrac{59.7}{145.125}\\\\\Rightarrow\ \sin X =0.41137\\\\\Rightarrow\ X = \sin ^{-1}(0.41137)\approx24.3^{\circ}[/tex]
Hence, the acute angle ∠YXZ = 24.3°.
Which of the following interpretations for the given expression is correct?
A.
The sum of 2 and the quotient of 9 and 3.
B.
The product of 2 + 9 and 3.
C.
The quotient of 2 + 9 and 3.
D.
The sum of 2 and the product of 9 and 3.
Answer:
the answer is the quotient of 2+9 and 3
Find the sum by first finding the equivalent fractions so both of the fractions have common
denominators.
Answer:
3x3/8x2 = 9/16
9/16+7/16 = 16/16

Un jardinier a récolté deux quintaux trois quarts de pommes . Il vend un quintal un quart à un voisin ; il vend aussi 7/10 de quintal sur le marché du village et 2/5 de quintal à un pâtissier .Exprimer à l'aide d'une fraction la quantité de pomme que le jardinier a gardé pour lui .
Answer:
Step-by-step explanation:
Notez que: un quintal =
une unité de poids égale à 100 kg
Un jardinier a récolté deux quintaux et trois quarts de pommes.
Le nombre total de pommes récoltées = 200 kg + 3/4 du quintal de pommes
= 200 kg + 0,381 kg
= 200,381 kg
Il vend un quintal un quart à un voisin
Le montant qu'il a vendu à un voisin = 100 + 1/4 quintal de pommes
100 + 0,127
= 100,127 kg
Il vend également 7/10 d'un quintal sur le marché du village
= 7/10 × 100 kg
= 70 kg de pommes restantes
2/5 d'un quintal à un pâtissier.
2/5 × 100 kg
= 40 kg de pommes restantes
À l'aide d'une fraction, exprimez la quantité de pomme que le jardinier a gardée pour lui.
La quantité que le jardinier lui a réservée =
200 3/4 kg - (100 1/4 kg + 70 kg + 40 kg)
200,381 kg - (210,127 kg)

Answer:
b) -9.8t +18
Step-by-step explanation:
b) The instantaneous rate of change is the derivative of the height function. The power rule is separately applied to each term, and the results added.
power rule: d/dx(x^n) = nx^(n-1)
Then the derivative is ...
dh/dt = 2(-4.9t^1) +18(1 ·t^0)
dh/dt = -9.8t +18
__
If you haven't been introduced to derivatives as such, then you find the instantaneous rate of change by finding the average rate of change over a vanishing interval.
[tex]\dfrac{dh}{dt}=\displaystyle\lim\limits_{h\to 0}{ \dfrac{h(t+h)-h(t)}{h}}\\\\\dfrac{dh}{dt}=\lim\limits_{h\to 0}\dfrac{(-4.9(t+h)^2+18(t+h)+23)-(-4.9t^2+18t+23)}{h}\\\\\dfrac{dh}{dt}=\lim\limits_{h\to 0}\dfrac{-4.9(2th+h^2)+18h}{h}=\lim\limits_{h\to 0}{(-9.8t +18 -4.9h)}\\\\ \boxed{\dfrac{dh}{dt}=-9.8t +18}[/tex]

What is the radius of a circle with the circumference 81.64
Answer:r≈12.99
Step-by-step explanation:
We can use the formula of the circumference of the circle. Which is given by:
Circumference = 2 \pi r
where "r" represents radius of the circle and , pi = 3.14
Plug the given values
81.64 = 2* 3.14* r
81.64 = 6.28 r
