23+87+98=208

2.08+1=3.08

3.08-----> 308p

Answer: 208 in^2

Step-by-step explanation:

find the surface area of the square base

8(8)=64

find the surface area of the 4 triangular lateral faces

SA=4(bh÷2)

4(8 x 9 ÷2)

4(36)=144

add the surface area of the square base and lateral faces

64+144=208

The rate of change is the slope. The slope is the number in front of the x

Function 1 rate of change is -1/2

Function 2 rate of change is -3/4

The greater rate of change would be the steepest slope.

Function 2 has the greater rate of change

Answer:

36.5miles/gallon

Step-by-step explanation:

Given the equation y=36.5x which represents the number of miles, y, that Katherine can drive her car for every, x, gallons of gas. The rate of change of the function is expressed as dy/dx

On differentiating the function;

dy/dx = 36.5

Hence the rate of change of the function is 36.5miles/gallon

Answer:

C

Step-by-step explanation:

When the divisor in an expression is a fraction, you use the reciprocal of the fraction. The reciprocal of the fraction 1/3 is 3/1. Therefore, it would be 3/4 times  3/1.

Gene therapy is a procedure used to treat and cure sickness by altering a person's gene structure, hence options C, D, and E are correct.

A type of genetic engineering is gene therapy. Gene therapy is a method of treating illnesses. Gene therapy involves replacing mutated genes.

rDNA technology is used in genetic engineering to recreate the genetic code. In order to treat and cure illnesses, gene therapy also modifies the gene. Gene therapy replaces damaged or mutant genes in order to treat illness.

It has a characteristic that offers promise in curing fatal illnesses including cancer, diabetes, AIDS, and many others. Through gene replacement therapy, defective genes are replaced with healthy ones.

Therefore, gene therapy is a form of genetic engineering, hence options C, D, and E are correct.

Answer:

S₁₅ = 645

Step-by-step explanation:

The sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Using the nth term formula [tex]a_{n}[/tex] = 5n + 3 , then

a₁ = 5(1) + 3 = 5 + 3 = 8

a₂ = 5(2) + 3 = 10 + 3 = 13 , then

d = a₂ - a₁ = 13 - 8 = 5

Thus

S₁₅ = [tex]\frac{15}{2}[/tex] [ (2 × 8) + (14 × 5) ]

     = 7.5( 16 + 70)

     = 7.5 × 86

     = 645

Answer:

400 cm²

Step-by-step explanation:

25÷20 = 1.25

Area = 1.25 × 320

= 400 cm²

Answer:

500

Step-by-step explanation:

Base is 20, height is 16, the larger one is 1.25 times larger, so the height of the larger one is 16*1.25=20. This means that the area of the larger one is 20*25=500.

Answer:

The absolute value of -9 is less than 9 I'm pretty sure

Answer:

45%

Step-by-step explanation:

45 out of 100 equals 45%.

===================================================

Explanation:

We could add 9 to both sides, and then apply the square root to both sides. Don't forget about the plus minus

x^2 - 9 = 0

x^2 = 9

x = sqrt(9) or x = -sqrt(9)

x = 3 or x = -3

To check these answers, you replace x with those values we found. I'll show you how to check x = 3

x^2 - 9 = 0

(3)^2 - 9 = 0

9 - 9 = 0

0 = 0

So that confirms x = 3. The confirmation for x = -3 is nearly the same. Keep in mind that (-3)^2 = (-3)(-3) = 9. You'll be squaring the negative as well.

------------------

Another method you could do is to use the difference of squares rule

x^2 - 9 = 0

x^2 - 3^2 = 0

(x - 3)(x + 3) = 0

Now apply the zero product property. This effectively means you set each factor equal to zero and solve for x

x-3 = 0 or x+3 = 0

x = 3 or x = -3

We end up with the same solution set.

Yet another method you could use is the quadratic formula, but that may be overkill. It's still good practice to do.

Graphing is a visual way to find the answers. You'll graph y = x^2 - 9 and look to see where the curve crosses or touches the horizontal x axis.

Answer:

2.575844

Step-by-step explanation:

This is a simple change of temp problem, from 539K to -62C but to start you have to change the C to K, which is simply adding 273 to the -62 so 211K.

Now you take P1/T1 = P2/T2 so,

6.58 = x

539 = 211

now cross multiply and divide, 211 x 6.58 then divide by 539.

this will give you your answer
