Explicación paso a paso:
Dado :
La frecuencia máxima del pulso que se debe mantener durante las actividades aeróbicas viene dada por:
0,88 (220-A); donde A = edad
Para una persona de 20 años
Supongamos que la edad es de 20 años; A = 20
Poniendo A = 20 en la ecuación;
0,88 (220 - A); A = 20
Frecuencia de pulso máxima:
0,88 (220 - 20)
0,88 (200)
= 176
La frecuencia de pulso máxima es 176

The value of the variable 'x' using the cosine formula will be 5.4 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
The value of 'x' is given by the cosine of the angle ∠LKM. And the cosine of an angle is the ratio of the base and hypotenuse of the right-angle triangle. Then we have
cos 19° = 5.1 / x
x = 5.4
The value of the variable 'x' using the cosine formula will be 5.4 units.

Which of the following equations is equivalent to 6(3p – 2) = 20?
18p – 2 = 20
18p – 12 = 20
9p – 8 = 20
9p – 4 = 20
Answer:
18p - 12 = 20
Step-by-step explanation:
=> 6(3p – 2) = 20
=> 6x3p – 6x2 = 20
=> 18p - 12 = 20
Answer:
18p -12 = 20
Step-by-step explanation:
6(3p – 2) = 20
Distribute
6*3p - 6*2 =20
18p -12 = 20
Paul's company rents cars to people who are at least 25 years old. Which graph best represents the possible ages of people who can rent cars from Paul's company?
A number line with an open circle on 25, with shading to the right.
A number line with a closed circle on 25, with shading to the right.
A number line with an open circle on 25, with shading to the left.
A number line with a closed circle on 25, with shading to the left.
Answer:
A number line with a closed circle on 25, with shading to the right.
Explanation:
A closed circle means "greater than or equal to" or "less than or equal to".
A open circle means "less than" or "greater than"
Therefore, since the question says: "who are at least 25 years old", a closed circle is the correct answer.
And says it says "at least 25 years old" it means that it shaded to the right, and that the circle is on the number 25.
Answer:
A number line with a closed circle on 25, with shading to the right.

If the measure of angle 5 is (3x + 50) degrees and the measure of angle 6 is (5x + 16) degrees, what value of x will guarantee equation AB \\ DE
Answer:
x = 17
Step-by-step explanation:
If AB // DE, then angle 5 and angle 6 are alternate interior angle and they should be congruent.
5x + 16 = 3x + 50
Subtract 16 from both sides
5x = 3x + 50 - 16
5x = 3x + 34
Subtract 3x from both sides
5x - 3x = 34
2x = 34
Divide both sides by 2
x = 34/2
x = 17
Answer:
To AB \\ DEangle 5 should be equal to angle 63x + 50 = 5x + 16
5x - 3x = 50-16
2x = 34
x = 17

Complete the function for this graph.
Answer:
k(x) = -2|x - (-3)| + 4
Step-by-step explanation:
Parent function for the graph is,
f(x) = |x|
If the parent function is vertically stretched by a scale factor of 2,
New function will be,
g(x) = 2|x|
If the function 'g' is reflected across x-axis,
h(x) = -2|x|
If the function 'h' is translated 3 units left and 4 units upwards, new function will be,
k(x) = -2|x - (-3)| + 4

=120 ÷2
=60
Answer is
z = 70
x = 70
Step-by-step explanation:
z is also equal to x because two sidess are equal
40 + x + x =180
40 + 2x = 180
2x = 140
x =70
so x and z are 70 each

y = x + 8
x + y = 2
Step 2: Solve for x
Substitution
Substitute in y [2nd Equation]: x + x + 8 = 2Combine like terms: 2x + 8 = 2[Subtraction Property of Equality] Subtract 8 on both sides: 2x = -6[Division Property of Equality] Divide 2 on both sides: x = -3Step 3: Solve for y
Substitute in x [1st Equation]: y = -3 + 8Add: y = 5Answer:
x = - 3
y = 5
Step-by-step explanation:
y = x + 8 ------(I)
x + y = 2 -------------(II)
Substitute y = x + 8 in equation (II)
x + x + 8 = 2
Combine like terms
2x + 8 = 2
Subtract r from both sides
2x = 2- 8
2x = -6
Divide both sides by 2
x = -6/2
x = -3
Plug in x = -3 in equation (I)
y = -3 + 8
y = 5

Answer:
B. neither perpendicular nor parallel
Step-by-step explanation:
to be perpendicular, the slopes have to be complete opposites. in this case, the second term would have to be y=-0.5x to be perpendicular. to be parallel, the two would have to have the same slopes; so y=2x and y=2x
