To draw a 50 degree angle with a protactor, proceed as follows :
Draw a straight line (i.e. an arm of the angle).Place a dot at one end of the arm. This dot represents the vertex of the angle.Place the centre of the protractor at the vertex dot and the baseline of the protractor along the arm of the angle.Find 50 degree angle on the scale and then mark a small dot at the edge of the protractor.Join the small dot to the vertex with a ruler to form the second arm of the angle.Label the angle with capital letters.Remember that 50 degree angle cannot be constructed using compass.

y = -(x - 2)² - 4
Step-by-step explanation:
The vertex of this function is (2, -4), which is given in the tableThe vertex form an equation is given as :
y = a(x - h)² + kSubstitute the vertexy = a(x - 2)² - 4Substitute any point in the table to find a :
-8 = a(0 - 2)² - 44a = -4a = -1Hence, the final equation :
y = -(x - 2)² - 4Option 2help pleaseeeeeee. i don’t onowww
in an exponential expression, the rate of change is usually the parenthesized expression, namely on y = a(b)ˣ, the rate will be "b", so in this case the rate is just ∛24
[tex]\sqrt[3]{24} ~~ \begin{cases} 24=2\cdot 2\cdot 2\cdot 3\\ \qquad 2^3\cdot 3 \end{cases}\implies \sqrt[3]{2^3 \cdot 3}\implies 2\sqrt[3]{3}[/tex]
A 5kg sample of plutonium-239 has a half-life of 21,400 years by emitting a 5.157 mev (million or mega electron volts) alpha particles. assume that the rate of decay is constant, how long will it take for the sample to degrade to 4.5kg?
Using an exponential function, it is found that it will take 3,252 years for the sample to degrade to 4.5kg.
What is the exponential function for the amount of a substance?It is given by:
[tex]A(t) = Pe^{-kt}[/tex]
In which:
P is the initial amount. k is the decay rate, as a decimal.The half-life is of 21,400 years, hence, A(21400) = 0.5P, and this is used to find k.
[tex]A(t) = Pe^{-kt}[/tex]
[tex]0.5P = Pe^{-21400k}[/tex]
[tex]e^{-21400k} = 0.5[/tex]
[tex]\ln{e^{-21400k}} = \ln{0.5}[/tex]
[tex]-21400k = \ln{0.5}[/tex]
[tex]k = -\frac{\ln{0.5}}{21400}}[/tex]
k = -0.00003239005
Hence, considering the initial mass is of P = 5 kg, the amount after t years is given by:
[tex]A(t) = 5e^{-0.00003239005t}[/tex]
The amount will be of 4.5 kg at t for which A(t) = 4.5, hence:
[tex]4.5 = 5e^{-0.00003239005t}[/tex]
[tex]e^{-0.00003239005t} = 0.9[/tex]
[tex]\ln{e^{-0.00003239005t}} = \ln{0.9}[/tex]
[tex]-0.00003239005t = \ln{0.9}[/tex]
[tex]t = -\frac{\ln{0.9}}{0.00003239005}[/tex]
t = 3252.

Which inequality is equivalent to −y≥18?
[tex]\rule{199}{1}[/tex]
Given question:-
Which inequality is equivalent to -y≥18?
Answer and how to solve:-
Divide by -1 on both sides to fully simplify the inequality, which is what we're asked to do.
So we get
y≤-18
Notice that the inequality sign changed.
The inequality sign changes when we divide both sides of an inequality by a negative number.

Please answer ! Polynomials and Factoring problems. Thank you!
Answer: The answer to your first question is b^2+2b-8. You second answer is y^2-4y+3.
Step-by-step explanation: Now, these questions deal with the FOIL method commonly taught in schools. The FOIL method is to turn factored binomials back into quadratics. Let's first go over what FOIL means.
F - First. So you multiply the first terms in each set of parenthesis, so b times b and y times y make b squared and y squared.
O - Outer. Multiply the two outer terms together, so b times -2 and y times -3. Remeber to pay attention to your signs when you multiply during these probelms!
I- Inner. Multiply the two inner terms together. so 4 times b and -1 times y. Again, make sure the signs are incorporated!
L - Last. Multiply the last terms in the binomials. So 4 times -2 and -1 times -3.
Now that we have our numbers, we have expanded quadratics that look like these:
b^2 -2b+4b-8 and y^2-3y-y+3
Now combine the two middle terms into +2b and -4y, and your answers are b^2+2b-8 and y^2-4y+3.

◆ First, the word "more" indicates that we add.
Here we have 19 more than c, so we add c plus 19, which looks as follows:-
✳︎ [tex]\sf{19+c}[/tex]
This expression is equal to 4:-
✳︎[tex]\sf{19+c=4}[/tex]
If you also need to find c, subtract 19 on both sides:-
c=-15So we conclude that the value of c is -15.

Answer:
19 + c = 4
Step-by-step explanation:
Given:
19 more than the number c is 4We know that:
The word "more" means addition between two numbers. The word "is" means two terms or two expressions are equivalent.Therefore, we can make the following replacements:
"19" ⇒ "19""more" ⇒ "+""c" ⇒ "c""is" ⇒ "=""4" ⇒ "4"When we replace the bolded text in the statement, we get;
⇒ 19 more than the number c is 4
⇒ 19 more than the number c is 4 ["19" ⇒ "19"]
⇒ 19 + than the number c is 4 ["more" ⇒ "+"]
⇒ 19 + c is 4 ["than the number c" ⇒ "c"]
⇒ 19 + c = 4 ["is" ⇒ "="]
⇒ 19 + c = 4 ["4" ⇒ "4"]
Thus, the expression/equation that represents the statement is [tex]\small\text{19 + c = 4.}[/tex]
