Answer:
Voltage V=220V
Current I=4A
Now, rate at which the electrical energy transformed
P=V×I
P=220×4
P=880 watts
Now, the energy is transformed in 2 min
P=tE
E=P×t
E=880×120
E=105600J
Hence, the energy transformed is 105600 J

y = x ^2+ 8x + 15 what is the vertex, axis of symmetry, and y-intercept? Pleaseee help
Answer:
Step-by-step explanation:
y = x^2 + 8x + 15
= x^2 + 8x + 4^2 - 4^2 + 15
= (x+4)^2-1
Answer:
(−4, −1)
vertex, axis of symmetry, and y-intercept: y = (x + 4)² −1

Two lines intersect at point b, which is also the endpoint of two rays. What is the measure of angle ABC
Answer:
The answer is "[tex]22^{\circ}[/tex]"
Step-by-step explanation:
Please find the question image file in the attachment:
In this question, [tex]\angle B =90^{\circ}[/tex], that is made up of the two complementary angles that are 57 and 3x.
So, the equation is:
[tex]\to 57+3x=90\\\\\to 3x=90-57\\\\\to 3x= 33\\\\\to x=\frac{33}{3}\\\\\to x= 11[/tex]
In [tex]\Delta ABC[/tex]:
BC=2x
put the value of x in above then [tex]BC= 2\times 11^{\circ} =22^{\circ}[/tex]

Which linear function has the greatest initial value? Which has the greatest rate of change? Use the drop-down menus to show your answer
Function A: (0,0) (2,5) (4,10) (6,15)
Function B: Y = 3x-1
Function C: picture***
Answer:
Step-by-step explanation:
The function C has the greatest initial value, and the function B has the greatest rate of change
Linear functionA linear function is a function whose value changes at a constant rate.
A linear function is represented as:
[tex]y = mx + c[/tex]
Where
m represents the ratec represents the initial value, or the value of the function, when x = 0Initial valuesThe initial value of function A is 0.
This is so because y = 0, when x = 0
The initial value of function B is -1
This is so because the value of function y = 3x - 1 is -1, when x = 0
From the graph, the initial value of function C is 2
Hence, the function C has the greatest initial value
Rate of changeRate of change is calculated as:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, the rate of change of function A is calculated as follows:
[tex]m = \frac{5 - 0}{2-0}[/tex]
[tex]m = \frac{5 }{2}[/tex]
[tex]m = 2.5[/tex]
The rate of change of function A is 2.5
The rate of change of function B is 3.
The rate of change of function C is calculated as follows:
[tex]m = \frac{3 - 2}{3-0}[/tex]
[tex]m = \frac{1}{3}[/tex]
The rate of change of function C is 1/3
Hence, the function B has the greatest rate of change

Hi there!
So what we need to do here is this...
Multiply -3/4 with there own parentheses and multiply 2 with it’s own parentthese also.
[tex]- \frac{3}{4} x 5p = 3 \frac{3}{4} p[/tex]
[tex]-\frac{3}{4} x 12 = 9[/tex]
Then do the second parenthese...
[tex]2x8=16[/tex]
[tex]2x - \frac{1}{4} = \frac{1}{2}p[/tex]
Add them like this...
[tex]( 3 \frac{3}{4}p + 9 ) + ( 16 -\frac{1}{2}p )[/tex]
Simplflied it again.../ since 3 3/4 and 1/2 both have p, add them...
[tex]3 \frac{3}{4} + - \frac{1}{2}p=3 \frac{1}{4}p[/tex]
Add the rest:
[tex]3 \frac{1}{4}p+9+16[/tex]
5. Find the slope. Make sure to reduce

Measure of angle s:
Sum all angles of triangle is = 180 degrees
So,

Discriminant=__
Number of solutions for the quadratic equation=___
a^2+3a=7
Answer:
two unequal, complex roots
Step-by-step explanation:
Rewrite this quadratic as a^2 + 3a - 7 = 0. The coefficients are {1, 3, -7}. The discriminant is b^2 - 4ac = 3^2 - 4(1)(-7), or 9 - 28, or -19.
Because the discriminant is negative, we know immediately that this quadratic has two unequal, complex roots.
What is the value ofx?
Answer:
x = 39
Step-by-step explanation:
∠JKL and ∠LKM are complementary angles meaning they have a sum of 90° Knowing this, we can create an equation to solve for x.
2x - 14 + 26 = 90
2x + 12 = 90
2x = 78
x = 39
Diego has a water bottle and pours 6.8 ounces of water out from the full bottle. He estimates that he poured out 20% of the water in the bottle
Answer:
34 ounces
Step-by-step explanation:
Here is the full question
Diego pours 6.8 ounces of water from a full bottle. He estimates that he poured out 20% of the water in the bottle. About how much water was in the full bottle?
Let b = total ounces in the bottle
the equation that can be derived from this question is :
0.2 x b = 6.8
To find b, divide both sides by 0.2
b = 6.8 / 0.2 = 34 ounces

solve for x. 9 4 13.5 x+4
Answer:
x = 2
Step-by-step explanation:
The parallel lines divide the transversals into proportional segments, that is
[tex]\frac{x+4}{13.5}[/tex] = [tex]\frac{4}{9}[/tex] ( cross- multiply )
9(x + 4) = 54 ( divide both sides by 9 )
x + 4 = 6 ( subtract 4 from both sides )
x = 2
