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

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.

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

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

-46 - 8x > 22

Step 2: Solve for x

Answer: x < −17/2

Step-by-step explanation:

Let's solve your inequality step-by-step.

−46 − 8x > 22

Step 1: Simplify both sides of the inequality.

−8x − 46 > 22

Step 2: Add 46 to both sides.

−8x − 46 + 46 > 22 + 46

−8x > 68

Step 3: Divide both sides by -8.

−8x/−8 > 68/−8

x < −17/2

just add up the lengths of the three sides

length of AB =

[tex] \sqrt{ {2}^{2} + {6}^{2} } [/tex]

length of BC

[tex] \sqrt{ {7}^{2} + {3}^{2} } [/tex]

length of CA

[tex] \sqrt{ {5 }^{2} + {1}^{2} } [/tex]

(yeah, it's with pythagoras)

let's sum everything up

length AB+BC+CA = 21.011

the units would just be considered as "length units" I guess

Answer:

Home Water Works says that in most homes, showers are the third-largest user of water after toilets and clothes washers. The average American shower water usage is 17.2 gallons with the average shower length being 8.2 minutes. The average flow rate is 2.1 gallons per minute.

Answer:

90.2 gallons

Step-by-step explanation:

This is because if we take 8.8 * 8.2=72.16

then we do 72.16*5 =360.8

360.8 / 4 = 90.2 gallons.

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.

Let's solve your equation step-by-step.

−8(z+4)=−7(z+−4)+−3

Step 1: Simplify both sides of the equation.

-8z-32=-7z+25

Step 2: Add 7z to both sides.

-z-32=25

Step 3: Add 32 to both sides.

-z=57

Answer:-57

Step-by-step explanation:

-8(z+4) = -7(z+-4)+-3

-8z-32= -7z+28-3

-8z-32=-7z+25

-57=z

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

Answer:

1/16

Step-by-step explanation:

They are independent events so we can multiply the probabilities

P(heads) = 1/2

P(4 heads) = P(heads)*P(heads)*P(heads)*P(heads)

                   = 1/2*1/2*1/2*1/2

                     = 1/16

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

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.

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

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:

[tex]x=4.02[/tex]

Step-by-step explanation:

The given triangle is a right triangle, this is indicated by the box around one of the angles, signifying that the angle is a (90) degree angle. Therefore, to solve this problem one must use trigonometric ratios. These ratios are used to describe the relationship between an angle and the sides in a right triangle.

[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}\\[/tex]

Bear in mind, the names of the sides of the triangle are relative to the angle that one uses to describe it in the triangle. Therefore the (opposite) and (adjacent) sides will change depending on the angle one chooses to look at it from.

In this case, one is given the length of the side opposite the given angle. One is asked to find the measure of the side adjacent to the angle. Therefore, it would make the most sense to use the tangent (tan) ratio.

[tex]tan(\theta)=\frac{opposite}{adjacent}[/tex]

Substitute,

[tex]tan(20)=\frac{9}{x}[/tex]

Manipulate the equation such that it is solved for (x),

[tex]x=\frac{9}{tan(20)}[/tex]

Solve,

[tex]x=4.02[/tex]
