Final answer:

The zeros of the function h(x)=(-4x-3)(x-3) are x=3/4 and x=3, with the smaller solution being 3/4 and the larger solution being 3.

Explanation:

To solve for x, we need to find the zeros of the function h(x) = (-4x-3)(x-3). The zeros of a function occur where the function equals zero, so setting h(x) to zero gives us:

0 = (-4x - 3)(x - 3)

A function is zero when any of its factors are zero. We can, therefore, set each factor equal to zero and solve:

-4x - 3 = 0 => x = -3/(-4) => x = 3/4

x - 3 = 0 => x = 3

So the zeros of the function are x = 3/4 and x = 3. The smaller solution is x = 3/4, and the larger solution is x = 3.

Answer:

x=11 and x=18

Step-by-step explanation:

The given quadratic equation is;

[tex](x-8)^2-13(x-8)+30=0[/tex]

Let u=(x-8)

[tex]u^2-13u+30=0[/tex]

Split the middle term;

[tex]u^2-10u-3u+30=0[/tex]

Factor by grouping

[tex]u(u-10)-3(u-10)=0[/tex]

[tex](u-10)(u-3)=0[/tex]

We have either u=10 or u=3

This implies that;

x-8=10 or x-8=3

x=10+8 or x=3+8

x=18 or x=11

Answer:

4153

Step-by-step explanation:

(x-3)/10 + 3000 = x-73

(x-3)/10 = x - 3738

x-3 = 10x - 37380

 x = 10x - 37377

-9x = -37377

 x = 4153

: P

Answer:

4153

Step-by-step explanation:

Let the original number be x

First, you subtract 3 from the original number. This removes 3 from the last digit, but leaves a zero there.

Now to remove the zero, you divide by 10.

Finally, to put the 3 at the first position, you add 3000.

Now Moving the last digit, 3, to the first position the number becomes :[tex]\frac{x-3}{10}+3000[/tex]

We are given that the number will decrease by 738.

A.T.Q

[tex]\frac{x-3}{10} + 3000 = x-738[/tex]

[tex]\frac{x-3}{10}= x - 3738[/tex]

[tex]x-3 = 10x - 37380[/tex]

[tex]x = 10x - 37377[/tex]

[tex]-9x = -37377[/tex]

[tex]x = 4153[/tex]

Hence the original 4-digit number is 4153.

Point D lies on the circumference of the unit circle

Step-by-step explanation:

Use the unit circle formula x^2 + y^2 = 1 plug the possible answer choices into this formula and determine  which one is true.

D(3/4,root 7/4) lies on the circumference of the unit circle , Option D is the correct answer.

A unit circle is a circle with 1 unit radius and the center is at origin .

The equation of a unit circle is x ² + y² =1

The points given are

A(4,3) B(1/2,1/5) C(0.6,0.7) D(3/4,root 7/4).

To check if they lie on the circumference of a unit circle , They have to be substituted in the equation of unit circle.

Point A

4 ² + 3² =1

16+ 9 ≠ 1

Point B

(1/2) ² + (1/5)² =1

(1/4) + (1/25) = 1

29/100  ≠ 1

Point C

(0.6) ² + (0.7)² =1

0.85 ≠ 1

Point D

(3/4)² + (√7/4)² =1

(9/16) + (7/16) = 1

1 = 1

Therefore , Option D,  D(3/4,root 7/4) lies on the circumference of the unit circle.

Answer:

108.505

Step-by-step explanation:

Let's talk money for just a second. Which would you rather have 20 dollars or 20.32      20dollars and 32 cents?

Isn't 20.32 bigger than 20.

You should say yes.

If that is true, then 108.505 should be larger than 108.5 not by much, but still larger.

After comparing digits after the decimal point, 108.505 is greater than 108.5 because 505 is greater than 500.

When comparing two decimal numbers, you should compare them digit by digit, starting from the leftmost digit. In this case, both numbers start with 108, which is the same. However, when comparing the next set of digits after the decimal point, you have 505 for the first number and 5 (equivalent to 500) for the second number. Because 505 is greater than 500, the first number, 108.505, is greater than the second number, 108.5.

255 - 6          = 10x

249               = 10x

x                    = 249/10 = 24.9

Given:

Find:

Solution:

The given equation is [tex]25\frac{1}{2} * 5 -3 = 5x[/tex]

Now, solving the equation, we get;

[tex]25\frac{1}{2} * 5 -3 = 5x[/tex]

[tex]\frac{51}{2} *5 - 3 =5x[/tex]

Now, multiplying the 51/2 with 5, we get;

[tex]\frac{255}{2} - 3 = 5x[/tex]

Now, we will take lcm and we get;

[tex]\frac{255-6}{2} = 5x[/tex]

[tex]\frac{249}{2} = 5x[/tex]

Now, multiplying with 2 on both sides of the equation, we get;

Answer:

x = 35 degrees.

Step-by-step explanation:

cos x = sin(20 + x)

Using the identity cos x = sin(90 - x):

20 + x = 90 - x

2x = 70

x = 35 degrees (answer).

Answer:

Value of x is 35°.

Step-by-step explanation:

Given:

cos x = sin ( 20 + x )

To find: Value of the x.

We know that [tex]sin\,(90-\theta)=cos\,\theta[/tex]

Consider,

cos x = sin ( 20 + x )

sin ( 90 - x ) = sin ( 20 + x )

Comparing both sides,

90 - x = 20 + x

-x - x = 20 - 90

-2x = -70

x = 35°

Therefore, Value of x is 35°.

[tex](\frac{f}{g})(x)=\frac{x^{2} +2x-3}{x^2-9}[/tex]  since x = 4, you plug in 4 into the x's in the equation

so [tex](\frac{f}{g})(4)=3[/tex]

(f + g)(x) = (x² + 2x - 3) + (x² - 9)     Plug in 4 for x

(f + g)(4) = 4² + 2(4) - 3 + (4)² - 9

Answer:

Perimeter=737 feets

Area=13542.6 ft²

Step-by-step explanation:

Well assuming that a,b,c are the three sides of the triangle and h is the height then;

Perimeter=distance around the figure

P=164+221+352= 737 feet

Area of a triangle given three sides is calculated using the formulae;

Area=√s (s-a) (s-b) (s-c) where  s=(a+b+c)/2

Finding s;

s=(164+221+352)/2 =368.5 feet

Finding the area

A= √ 368.5 (368.5-164) (368.5-221) (368.5-352)

A=√368.5 (204.5) (147.5) (16.5)

A= 13542.6 ft²

Answer: 39 degrees

Step-by-step explanation: The angle sum of a triangle is 180 degrees so we take 102 from 180.

180-102=78

Since the two angles are the same then we just divide 78 by 2

78/2=39

Answer:

∠E ≈ 37°

Step-by-step explanation:

Using the Sine Rule in ΔEFG, that is

[tex]\frac{26}{sinE}[/tex] = [tex]\frac{42}{sin102}[/tex] ( cross- multiply )

42 × sinE = 26 × sin102° ( divide both sides by 42 )

sinE = [tex]\frac{26(sin102)}{42}[/tex] ≈ 0.6055..

E = [tex]sin^{-1}[/tex] (0.6055 ) ≈ 37°

The two angles are supplementary angles and make a straight line.

This means when added together they need to equal 180 degrees.

x + 34 + 2x + 2 = 180

Combine like terms:

3x + 36 = 180

Subtract 36 from each side:

3x = 144

Divide both sides by 3:

x = 48

the hypotenuse is always the line directly in front of the right angle.

Part 1) [tex]HD=\sqrt{105}\ units[/tex]

Part 2) [tex]JD=2\sqrt{34}\ units[/tex]

Part 3) [tex]KD=6\sqrt{2}\ units[/tex]

Step-by-step explanation:

step 1

Find the length HD

In the right triangle HDF

Applying the Pythagoras Theorem

[tex]FD^{2} =HF^{2} +HD^{2}[/tex]

substitute the values and solve for HD

[tex]19^{2} =16^{2} +HD^{2}[/tex]

[tex]HD^{2}=19^{2}-16^{2}[/tex]

[tex]HD=\sqrt{105}\ units[/tex]

step 2

Find the length JD

In the right triangle JDF

Applying the Pythagoras Theorem

[tex]FD^{2} =JD^{2} +FJ^{2}[/tex]

we have

[tex]FD=19\ units[/tex]

[tex]FJ=JG=15\ units[/tex] ----> because JD is a perpendicular bisector

substitute the values and solve for JD

[tex]19^{2} =JD^{2} +15^{2}[/tex]

[tex]JD^{2}=19^{2}-15^{2}[/tex]

[tex]JD^{2}=136[/tex]

[tex]JD=\sqrt{136}\ units[/tex]

[tex]JD=2\sqrt{34}\ units[/tex]

step 3

Find the length KD

In the right triangle KDG

Applying the Pythagoras Theorem

[tex]GD^{2} =KD^{2} +GK^{2}[/tex]

we have

[tex]GD=FD=19\ units[/tex]

[tex]GK=17\ units[/tex]

substitute the values and solve for KD

[tex]19^{2} =KD^{2} +17^{2}[/tex]

[tex]KD^{2}=19^{2}-17^{2}[/tex]

[tex]KD^{2}=72[/tex]

[tex]KD=\sqrt{72}\ units[/tex]

[tex]KD=6\sqrt{2}\ units[/tex]

Answer:

Option A

Step-by-step explanation:

Given

m=( y_2- y_1)/(x_2-x_1 )

In order to get the equivalent equation, multiplying the denominator x_2-x_1with m.

m(x_2-x_1 )=y_2- y_1

Adding y1 to both sides of equation will give:

m(x_2-x_1 )+ y_1=y_2- y_1+y_1

So the end result will be:

m(x_2-x_1 )+ y_1=y_2

Can also be written as:

y_2=m(x_2-x_1 )+ y_1

Comparing it the given options gives us that Option A is the correct answer.

The Correct answer is A
