. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.
Answer: [tex]3^{\circ}C[/tex]
Step-by-step explanation:
Given
The temperature on Monday was [tex]-5^{\circ}C[/tex]
By Tuesday, it becomes [tex]-2^{\circ}C[/tex]
Change in temperature is the difference between the two temperatures.
[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]
Therefore, the change in temperature is [tex]3^{\circ}C[/tex].

WILL GIVE BRAINLIEST AND THANKS. determine if these are tangent to the circle
Answer:
19 Five is not tangent to the circle.
20 Eight is tangent to the circle.
Step-by-step explanation:
In order for one of the legs to be a tangent to a circle, the length must be part of a right angle triple.
I don't think the diagram on the left is, but I'll check it.
5^2 + 12^2 =
25 + 144 =
169
square root of 169 is 13
The length of the hypotenuse should be 13 not 14. Fourteen does not make Pythagorean triple. 13 would. So the line 5 units long does not make a tangent to the given circle.
The diagram on the right is a different story. 6 8 and 10 do make a Pythagorean triple, even though the two diagrams are not the same.
The radius and the distance to the external point form a right angle.
The Pythagorean triple is
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
Hey! can someone help me find the value of x please??!
Answer:
x = 13
Step-by-step explanation:
The triangles base angles are congruent, so the triangle is isosceles with the 2 legs being congruent, then
x = 13

Work out the mean for the data set
below:
2.3, 0.3, 7,6.1, 9.7
Give your answer as a decimal.
Answer:
Mean = 5.08
Step-by-step explanation:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
[tex] \frac{2.3 + 0.3 + 7 + 6.1 + 9.7}{5} [/tex]
[tex] = \frac{25.4}{5} [/tex]
= 5.08

Does anyone know how to solve this?
Given :
A right angle triangle ABC .
To Find :
The perimeter of ABC .
Solution :
Since, triangle ABC is right angled and angle ∠ABC is 46° .
So, AC = AB cos 46° = 7.64 units.
Also, CB = AB sin 46° = 7.91 units.
Therefore, the perimeter of ΔABC is :
P = 11 + 7.64 + 7.91 units
P = 26.55 units
Hence, this is the required solution.
Factor completely 18x2 − 21x −15. 3(2x + 1)(3x − 5) 3(2x − 5)(3x + 1) 3(2x − 1)(3x + 5) 3(6x + 1)(x − 5)
Answer:
3(2x + 1)(3x - 5)
Step-by-step explanation:
Given
18x² - 21x - 15 ← factor out 3 from each term
= 3(6x² - 7x - 5 ) ← factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 6 × - 5 = - 30 and sum = - 7
The factors are + 3 and - 10
Use these factors to split the x- term
6x² + 3x - 10x - 5 ( factor the first/second and third/fourth terms )
3x(2x + 1) - 5(2x + 1) ← factor out (2x + 1) from each term
(2x + 1)(3x - 5)
Then
18x² - 21x - 15 = 3(2x + 1)(3x - 5)
Answer:
A
Step-by-step explanation:
Consider this equation
3x+ 1=2x-5
Answer: x=-6
Step-by-step explanation:
Add 5 to both sides to get 2x by itself
Yes, subtract 1 from both sides to get 3x by itself so you can subtract 2x as to not get a negative x value
One common mistake would be to accidentaly adding or subtracting 1 or 5 when they are supposed to be added/subtracted. To avoid this just go back and check your awnser by plugging it in.

PLEASE HELP ME WHAT IS THE ANWSER
Answer:
c is the same angle as a
b and d are the same as the other
and together the are what's left from 360° after a and c got their share
so
360 -98 -98 = b + d
makes
164 = b + d
since they are of equal value, just decide 164 by 2 and you got b and d at once
pls brainliest
Answer:
Vertical Angles: a and c , d and b
m<b= 82⁰ , m<c=98⁰ , m<d=82⁰
Adjacent Angles: a and b , b and c , c and d ,d and a

what are the answer to this question
Answer: t=-3h+25
Step-by-step explanation:
t=-3h+25
25 degrees is a constant-- it never changes, no matter how many hours goes by. So, you don't multiply a variable with it.
The temperature drops every 3 hours-- this is not constant, since it's dependent on the number of hours that passes. So, use a variable here. Since the temperature drops every three hours, it's -3, and not 3.
Answer:
[tex]t=-3h+25[/tex]
Step-by-step explanation:
If we know that when [tex]h=0[/tex], [tex]t=25[/tex], then we can use a direct proportion equation ([tex]x=ky[/tex]). The temperature decreases every hour by 3 degrees. However, we know that before any temperature drop, the temperature was 25 degrees. All together, this gives us [tex]t=-3h+25[/tex], where [tex]-3h[/tex] is the temperature drop each hour, and [tex]25[/tex] is the starting temperature. Hope that explained things :)

A 525ft cable runs from the top of an antena to the ground. The angle of elevation made by the ground to the top of an antena 25°
How tall is the antena ??
Answer:
221.87 feet
Step-by-step explanation:
Given that,
A 525 ft cable runs from the top of an antenna to the ground.
The angle of elevation made by the ground to the top of an antena 25°
We need to find the height of the antenna.
Using trigonometry,
Hypotenuse, H = 525 ft
θ = 25°
So,
[tex]\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=525\times \sin(25)\\\\P=221.87\ ft[/tex]
So, the height of the antenna is equal to 221.87 feet.

Answer:
y = x
Step-by-step explanation:
i took two points which are very close to the trend line - (3,3) and (5,5) - to get the slope
the slope is 2/2 or 1 and the y-intercept is zero
this means the trend line is 'y = x'
Help me please!!! I really need it!
Answer: The value of x can be either 5 or 10.
Step-by-step explanation:
We are given:
Total profit, P = $5600
The given equation follows:
⇒ P = 600 + 1500x - 100x²
Putting value of P in above equation, we get:
⇒ -100x² + 1500x + 600 = 5600
⇒ -100x² + 1500x - 5000 = 0
⇒ 100x² - 1500x + 5000 = 0
Solving this equation by middle term split, we get:
⇒ 100(x² - 15x + 50) = 0
⇒ (x² - 10x - 5x + 50) = 0
⇒ x(x - 10) - 5(x -10) = 0
⇒ (x - 10)(x - 5) = 0
⇒ x = 10, 5
Hence, the value of x can be either 5 or 10.
