Evaluate the following expression. You should do this problem without a calculator. log4 4 A. 4 B. C. 8 D. 1 SUBMIT
Given:
The given expression is:
[tex]\log_44[/tex]
To find:
The simplified value for the given expression.
Solution:
According to the property of logarithm,
[tex]log_aa=1[/tex]
We have,
[tex]\log_44[/tex]
Here, the base of the logarithm is 4 and the value inside the log is also 4, since these two values are same therefore the value of this expression is 1 by using the above property of logarithm.
[tex]\log_44=1[/tex]
Hence, the correct option is D.
By evaluating log4 4 without a calculator, we discover that it is equal to 1.

Suppose a triangle has two sides of length 2 and 3 and that the angle between these two sides is 60degrees. What is the length of the third side of the triangle?
Answer:
A) 2
Step-by-step explanation:
The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.
sin(A)/a=sin(B)/b=sin(C)/c
Substitute the known values into the law of sines to find a.
sin(60)/a=sin(60)/2

Type the correct answer in the box. Use numerals instead of words. Consider the logarithmic function f(x)=log^10(x) The values of f(50) rounded to the nearest hundredth is____
Answer:
1.70
Step-by-step explanation:
Logarithmic functions are the inverses of exponential functions. Hence, exponential functions can be expressed in logarithmic form whereas logarithmic function can be expressed in exponential form. Since log is a function, it is most correctly written as log.
Given that f(x) = log₁₀(x)
To find the value of f(50), we substitute x to be 50 in the logarithm function and solve:
f(50) = log₁₀(50)
f(50) = log₁₀(5 * 10) = log₁₀(5) + log₁₀(10)
f(50) = 1 + log₁₀(5) = 1 + 0.70
f(50) = 1.70

What is the sale price of crocs which regularly cost $35, but now are 30% off
Answer:24.5
Step-by-step explanation:30% of 35 is 10.5. To find the 30% off- you multiply 35 times 0.3 which is 10.5. Then you subtract the 10.5 from 35 for the total cost. 35-10.5=24.50
Answer:
the answer is 24.5
First you multiply 35 x 0.3 = 10.5, then subtract 10.5, 35-10= 24.5
Which in total the answer is 24.5
In circle F with m \angle EFG= 122m∠EFG=122 and EF=16EF=16 units, find the length of arc EG. Round to the nearest hundredth.
Given:
In circle F, [tex]m\angle EFG=122^\circ,\ EF=16[/tex] units.
To find:
The length of arc EG.
Solution:
It is given that, [tex]m\angle EFG=122^\circ,\ EF=16[/tex] units. It means the central angle of arc EG is 122 degrees and the radius of the circle F is 16 units.
Formula for arc length is:
[tex]s=2\pi r\times \dfrac{\theta}{360^\circ }[/tex]
Where, r is the radius and [tex]\theta [/tex] is the central angle in degrees.
Putting [tex]r=16,\ \theta=122^\circ,\ \pi=3.14[/tex], we get
[tex]s=2(3.14)(16)\times \dfrac{122^\circ}{360^\circ }[/tex]
[tex]s=100.48\times \dfrac{61}{180}[/tex]
[tex]s=34.0515556[/tex]
[tex]s\approx 34.05[/tex]
Therefore, the length of arc EG is 34.05 units.

State the slope and the y-intercept for the graph of the equation. y= -2
1; -2
0; -3
-2; 0
0; -2
Answer: 0; -2
Step-by-step explanation:
Data: y-intercept=x and slope=x
Equation=y=-2
Only step, Point out the y-intercept and slope
-2=y-intercept
0=slope
Reason: Since there is no visible slope, the placeholder would be 0 therefore the slope would be 0, -2 is the only number left so that means the only number that can be y-intercept is -2.
That is why the slope is 0 and the y-intercept is -2

Diego’s family car holds 14 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less.
1. Starting from a full tank, can Diego's family drive the car for 14 days without the warning light coming on? Explain your reasoning.
2. Starting from a full tank, can Diego’s family drive the car for 25 days without the warning light coming on? Explain your reasoning.
3. Diego says the expression 14 - 0.6t helps him to understand this situation. What does this expression represent, and what does the variable t stand for?
4. Write and solve an equation to determine the number of days Diego’s father can drive the car without the warning light coming on.
5. Write and solve an inequality that represents this situation. Explain clearly what the solution to the inequality means in the context of this situation.
Answer:
1) if he wants to do that he needs 0.6 gallons x 14 days = 8,4 gallons.
If the car starts with 14 gallons then he is able to ride 14 days without the warning light.
2) now he would need 0.6 gallons x 25 days = 15 gallons.
he only has 14 gallons so that is not possible.
3) no clue sorry
4) x= the days he can drive without the warning light
14-1,5 = 0,6.x
<=>12,5= 0,6.x
<=>20,833... = x
He can go 20 days without the warning light.
5) x= the days he can drive his car without seeing the warning light.
x.0,6<12,5
<=> x<20,833...
If he drives 20,833... days he will see the warning light so everything before that he won't see it.

The points ( − 4 , 9 ) and ( 4, −9) lie on the same line. What is its equation in slope-intercept form of this line?
Answer:
y = -9/4x
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
= ( -9-9)/(4 - -4)
( -9-9)/(4+4)
-18/8
-9/4
Slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = -9/4 +b
Substitute a point into the equation
9 = -9/4(-4) +b
9 = 9+b
b=0
y = -9/4x

Answer:
Vertical change of point C to B = 4.5
Vertical change of point A to D = -4
Step-by-step explanation:
Vertical change of a point is the rise of the given point.
Now we have to calculate the rise of point C to B,
y-coordinate of the point C → -2.5
y-coordinate of the point B → 2
Rise from C to B = 2 - (-2.5)
= 2 + 2.5
= 4.5
Similarly, y - coordinate of point A → 2
y - coordinate of point D → -2
Vertical change or rise = -2 - 2
= -4
Therefore, vertical change of point C to B = 4.5
Vertical change of point A to D = -4

Michelle throws a frisbee into the air. The height of the frisbee at a given time can be modeled by the equation h(t)= -2t
Answer:
(a) The ball will hit the ground after 3 seconds
(b) The maximum height is 6.125
Step-by-step explanation:
Given
[tex]h(t) = -2t^2 +5t +3[/tex]
Solving (a): When the frisbee will hit the ground?
To do this, we set h(t) to 0
So, we have:
[tex]h(t) = -2t^2 +5t +3[/tex]
[tex]-2t^2 +5t +3=0[/tex]
Expand
[tex]-2t^2 +6t-t +3=0[/tex]
Factorize
[tex]-2t(t - 3) -1(t - 3) = 0[/tex]
Factor out t - 3
[tex](-2t -1)(t - 3) = 0[/tex]
Split:
[tex]-2t -1= 0\ or\ t - 3 = 0[/tex]
Solve for t in both equations
[tex]-2t =1\ or\ t = 3[/tex]
[tex]t =-\frac{1}{2}\ or\ t = 3[/tex]
Time can't be negative; So:
[tex]t = 3[/tex]
Solving (b): How height the frisbee will go?
First, we calculate time to reach the maximum height
[tex]t = -\frac{b}{2a}[/tex]
Where:
[tex]h(t) = at^2 + bt + c[/tex]
By comparison:
[tex]a = -2,\ b =5,\ c =3[/tex]
So:
[tex]t = -\frac{b}{2a}[/tex]
[tex]t = -\frac{5}{2*-2}[/tex]
[tex]t = \frac{5}{4}[/tex]
[tex]t = 1.25[/tex]
So, the maximum height is:
[tex]h_{max} = -2 * 1.25^2 + 5 * 1.25 + 3[/tex]
[tex]h_{max} = 6.125[/tex]

Answer:
a+4=11b
Step-by-step explanation:
Distributive property in mathematics means to multiply the sum by a number of two or more add-ons will provide the same result that each add-on multiplies by a single number and then together add the products.
for example a( b+c) = ab+ac
Therefore, applying distributive property in asked eapression
12(2a - 6b+ 8) = 21(2a−6b+8)
24a+72b+96 = 42a-126b+168
198b=18a+72
9a +36=99b
3a+12=33b
a+4=11b
