Find the distance between the two points rounding to the nearest tenth (if necessary).
(−1,−2) and (5,2)
Answers
Answer:
7.2 units
Step-by-step explanation:
To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Plug in the given values of (-1, -2) & (5, 2)
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(5 - (-1))² + (2 - (-2))²]
Simplify the parentheses.
d = √[(5 + 1)² + (2 + 2)²]
d = √[(6)² + (4)²]
Simplify the exponents.
d = √[36 + 16]
Add.
d = √[52]
Evaluate the radical.
2√13 or 7.2111
Round the decimal.
7.2 units

[tex]y = \frac{1}{2} e^{x}[/tex] equation is represented by the given graph.
What is graph?
"Graph is defined as the representation of relation between two variables on the coordinate plane."
According to the question,
From the observation of the graph,
for x= 0
y- intercept = [tex]\frac{1}{2}[/tex]
a. [tex]y = \frac{1}{8} e^{x}[/tex]
Substitute x = 0 in the equation we get,
[tex]y = \frac{1}{8} e^{0}[/tex]
⇒ [tex]y = \frac{1}{8}[/tex]
Therefore,
Option (a) is not the correct answer.
b. [tex]y = \frac{1}{2} e^{x}[/tex]
Substitute x = 0 in the equation we get,
[tex]y = \frac{1}{2} e^{0}[/tex]
⇒ [tex]y = \frac{1}{2}[/tex]
which is same as graph value.
Hence, Option (b) is the correct answer.

y^2 + 576= 1296
y^2= 720
y= [tex]12\sqrt{5}[/tex]

Dillon peeled 40 pounds of potatoes. How many ounces of potatoes did Dillon peel?
Answers
Answer:
640
Step-by-step explanation:
40 pounds = 640 ounces
The ounces of potatoes that Dillon peeled is 640 ounces.
What is Unit Conversion?Unit conversion is defined as expressing the same quantity by different measurement units.
For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.
Given that,
Amount of potatoes that Dillon peeled = 40 pounds
We have to convert the same amount of potatoes in to the measurement unit of ounces.
We have to convert the unit.
We have the measurement unit that,
1 pound = 16 ounces
40 pounds = 40 × 16 = 640 ounces
Hence 640 ounces of potatoes did Dillon peel.

Sine cannot be greater than 1.
The given conditions cannot form a triangle, there is no possible value of K.
What is sine law?In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
Given that, in a triangle Δ IJK, k = 64 inches, j = 17 inches and ∠J = 68°.
We need to find value of ∠K,
So, using the sine law,
Sin K / k = Sin J / j = Sin I /i
So,
Sin K / k = Sin J / j
Sin K / 64 = Sin 68° / 17
Sin K = 3.5
K = Sin⁻¹(3.5)
K = ERROR
Hence, the given conditions cannot form a triangle, there is no possible value of K.
