How is the answer 6 when I keep getting the answer 9.16
Answer:
The value of given expression is 6.
Step-by-step explanation:
Given expression is;
[tex]\sqrt{5x^2-(-x^4)}[/tex]
We have to solve the expression when x = -2
Putting x = -2 in the given expression,
Solution = [tex]\sqrt{5(-2)^2-(-(-2)^4))}\\[/tex]
Solution = [tex]\sqrt{5(4) - (-16)[/tex]
Solution = [tex]\sqrt{20+16}[/tex]
Solution = [tex]\sqrt{36}[/tex]
Taking square root of 36
Solution = 6
Thus,
[tex]\sqrt{5x^2-(-x^4)}[/tex] = 6
Hence,
The value of given expression is 6.

Step-by-step explanation:
The equivalent expression for the expression -2/5(15 - 20d + 5c) is
-6 + 8d - 2c
Option B is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
-2/5 x (15 - 20d + 5c)
= -2/5 x 15 + 2/5 x 20 - 2/5 x 5c
= -2 x 3 + 2 x 4 - 2c
= -6 + 8d - 2c
Thus,
The equivalent expression is -6 + 8d - 2c.

Sandy ate 1/6 of a candy bar. John ate 3/4 of it. How much more of the candy bar did John eat than Sandy?
Explain how you solved.
step by step plesae AM TIMED
Answer:
John ate 7/12 more of the candy than Sandy.
Step-by-step explanation:
3/4 is equivalent to 9/12.
1/6 can be expressed as 2/12.
Step 3: 9/12 - 2/12 = 7/12.
Now that they have the same denominators, perform the subtraction process.
Then,John ate 7/12 more of the candy than Sandy.
The coordinates of triangle DEF are D(4,2), E(7,2), and F(6,8). If you translate triangle DEF 4 units right and 3 units down, what are the coordinates of E'?
Answer:
E’ is (11,-1)
Step-by-step explanation:
Here, we want to get the new coordinates of E
The translation is 4 units right ( add 4 to x-value) and 3 units down ( subtract 3 from y-value)
So for E, we have
(7 + 4, 2-3)
= (11, -1)

a family has a monthly budget of $2,400 how much money is spent on each category? 44% is spent on housing
Answer: See explanation
Step-by-step explanation:
Here's the complete question:
A family has a monthly budget of $2,400. How much money is spent on each category? 44% is spent on housing. 23% is spent on food. 6% is spent on clothing. 17% is spent on transportation. The rest is put into savings.
Housing = 44%
Food = 23%
Clothing = 6%
Transportation = 17%
Savings = 1 - (44% + 23% + 6% + 17%) = 10%
Amount spent on Housing = 44% × $2400 = 0.44 × $2400 = $1056
Amount spent on Food = 23% = 23% × $2400 = 0.23 × $2400 = $552
Amount spent in Clothing = 6% = 6% × $2400 = 0.06 × $2400 = $144
Amount spent on Transportation = 17% = 17% × $2400 = 0.17 × $2400 = $408
Savings = 10% = 10% × $2400 = 0.1 × $2400 = $240

Five cats each ate 1/5 of canned food and 1/5 cup of dry food. How much food did they eat altogether?
Answer:
2
Step-by-step explanation:
With regards to the above, we can sum up the foods ate together by the 5 cats, then we have;
= 1/5 + 1/5
= 2/5
Then we can multiply the value above by the 5 cats
= 2/5 × 5
= 10/5
= 2
The cats eat 2 foods together.

Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
c² = 42² + 56² = 1764 + 3136 = 4900 ( take the square root of both sides )

Un movil que ha partido de reposo inicia un M.R.U.A al cabo de 8seg, cambia su rapidez a 60m/seg. Hallar la distancia recorrida por el movil. Hacer grafica
Answer:
La distancia recorrida por el móvil es 240 metros.
Step-by-step explanation:
Puesto que el móvil experimenta movimiento rectilíneo uniformemente acelerado, la distancia recorrida es determinada por las siguientes ecuaciones cinemáticas:
[tex]\Delta x = v_{o}\cdot t + \frac{1}{2}\cdot a\cdot t^{2}[/tex] (1)
[tex]v = v_{o} + a\cdot t[/tex] (2)
Donde:
[tex]\Delta x[/tex] - Distancia recorrida, medida en metros.
[tex]v_{o}[/tex] - Velocidad inicial, medida en metros por segundo.
[tex]v[/tex] - Velocidad final, medida en metros por segundo.
[tex]a[/tex] - Aceleración, medida en metros por segundo al cuadrado.
[tex]t[/tex] - Tiempo, medido en segundos.
En (2) despejamos el tiempo:
[tex]a = \frac{v-v_{o}}{t}[/tex]
Si aplicamos esta ecuación en (1):
[tex]\Delta x = v_{o}\cdot t + \frac{1}{2}\cdot \left(\frac{v-v_{o}}{t} \right)\cdot t^{2}[/tex]
[tex]\Delta x = v_{o}\cdot t + \frac{1}{2}\cdot (v-v_{o})\cdot t[/tex]
[tex]\Delta x = \frac{1}{2}\cdot v_{o}\cdot t+\frac{1}{2}\cdot v\cdot t[/tex]
[tex]\Delta x = \frac{1}{2}\cdot (v_{o}+v)\cdot t[/tex] (3)
Si sabemos que [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]v = 60\,\frac{m}{s}[/tex] and [tex]t = 8\,s[/tex], entonces la distancia recorrida es:
[tex]\Delta x = \frac{1}{2}\cdot \left(0\,\frac{m}{s}+60\,\frac{m}{s}\right) \cdot (8\,s)[/tex]
[tex]\Delta x = 240\,m[/tex]
This year Martin's income is 1/4 greater than his income from Last year. If s represents his income from last year, what is his income this year?
Answer: 1 1/4s or 1.25s
Step-by-step explanation:
From the question, we are informed that this year Martin's income is 1/4 greater than his income from last year. We are further told that his income from last year is represented by s.
Therefore, hus income this year will be:
= s + (1/4 × s)
= s + 1/4s
= 1 1/4s or 1.25s
Answer:
it is 1/4s

On a map 3 inches = 20 miles if the distance between two cities on the map is 15 inches how many miles apart are they
Answer:
100 miles is the answer
Step-by-step explanation:
3 inches = 20 miles
15/3 = 5
5 x 20
= 100 miles
========================================================
Work Shown:
(3 inches)/(20 miles) = (15 inches)/(x miles)
3/20 = 15/x
3*x = 20*15
3x = 300
x = 300/3
x = 100
Therefore, 15 inches on the map correspond to 100 miles in real life.
-------------------
We could approach the problem like this:
3 inches = 20 miles
5*(3 inches) = 5*(20 miles)
15 inches = 100 miles
In the second step, I multiplied both sides by 5 to turn the "3 inches" into "15 inches".

A, B and C are three similar shapes.
The surface area of shape A is 4 cm2
.
The surface area of shape B is 25 cm2
.
The ratio of the volume of shape B to the volume of shape C is 27 : 64.
Work out the ratio of the height of shape A to the height of shape C.
Simplify your answer, and give it in the form A : C.
+explanation pleasee :)
============================================================
Explanation
Shape A has surface area 4 cm^2
Shape B has surface area 25 cm^2
The ratio of the surface areas, from A to B, is 4:25
Apply the square root to both parts and we get 2:5 as the ratio of the corresponding sides. If shape A has a height of 2, then shape B will have a corresponding height of 5. I recommend drawing out two squares with these properties to see that their areas form the ratio mentioned above.
The ratio of the volume of shape B to shape C's volume is 27:64. Apply the cube root to both parts to get 3:4. This means if the height of shape B is 3, then the corresponding height on shape C is 4.
-----------------------
We found these ratios for the sides
A:B = 2:5B:C = 3:4The goal is to find the ratio A:B:C which ties all three shapes together showing how they all connect in terms of their corresponding sides.
Note how in A:B = 2:5 we have B = 5, but in B:C = 3:4 we have B = 3. We cannot combine the two ratios in this form since the B terms don't match.
The good news is that we can apply scaling to get the B values to match up
The ratio 2:5 is equivalent to 6:15 after multiplying both parts by 3
The ratio 3:4 is equivalent to 15:20 after multiplying both parts by 5.
The multipliers 3 and 5 are used because note how 15 is the LCM of those previous B values mentioned.
-----------------------
After scaling those ratios, we have
A:B = 6:15B:C = 15:20From here, we can quickly see that A:B:C = 6:15:20. This is possible because the '15's match up for the B terms.
If shape A has a height of 6, then shape B has a height of 15, and C has a height of 20. All of these heights correspond to one another.
Then we just erase out the B part to conclude A:C = 6:20 which reduces to A:C = 3:10 after dividing both parts by 2.

Answer: y= -3/8|x|
Step-by-step explanation: so D oh khan academy
The function after reflection is y= -3/8 |x|
What is Translation?Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.
A transformation known as a translation involves shifting each point in a figure by the same amount and in the same direction.
Given:
y= |x|
So, reflection for x axis
y= -|x|
and, scaled vertically by a factor of 3/8
y= -3/8 |x|
Hence, the function after reflection is y= -3/8 |x|
