Answer:

640

Step-by-step explanation:

y = 40(4)^x

x = 26/13 = 2

y = 40(4)^2

y = 40 (16)

y = 640

it's infinitely many bc the equations have the same line

Answer:

a1x + b1y + c1 = 0

a2x + b2y + c2 = 0

Here a1, b1, c1, a2, b2, c2 are all real numbers.

Note that, a12 + b12 ≠ 0, a22 + b22 ≠ 0

Step-by-step explanation:

How many solutions does the following system have?

y = -2x – 4

y = 3x + 3

Solution:

Given y = -2x – 4

y = 3x + 3

Rewriting to the general form

-2x – y – 4 = 0

3x – y + 3 = 0

Comparing the coefficients,

(a1/a2) = -⅔

(b1/b2) = -1/-1 = 1

(a1/a2) ≠ (b1/b2)

Hence, this system of equations will have only one

Answer:

42.64°

Step-by-step explanation:

Note: A rhombus has all its sides equal, its opposite angle are equal, its  has bigger and smaller diagonal, diagonal bisect the angles and diagonal bisect each other.

From the diagram attached,

sinθ = opposite/adjacent

sinθ  = 4/11

θ = sin⁻¹(4/11)

θ = 21.32

Therefore, from the diagram,

The smaller angle of the rhombus = 2θ

The smaller angle of the rhombus = (2×21.32)

The smaller angle of the rhombus = 42.64°

When we construct the confidence interval their sample must have some conditions which are as follows,

Therefore , these are the conditions which the administrator should use to construct a one-sample z interval for a proportion.

When two ratios are equivalent to each other , they are said to be in a state called proportion. The proportion formula is used to see whether  the given ratios or fractions are equal or not . The proportion formula can be given as, The product of means is equal to the the product of extremes. This can be written as ad = bc.

Answer:

B) 15

Step-by-step explanation:

only options are 15 or 7 inches because the problem mentioned the triangle is isosceles (they have two equal sides)

we can eliminate 7 because of the triangle inequality theorem

if two sides of a triangle are 7 then their sum is only 14 and it would need to be greater than the third side of 15

Step-by-step explanation:

[tex]\sf \hookrightarrow \: x + x + 88 = 180 \\ \sf \hookrightarrow \: 2x +88 = 180 \\ \sf \hookrightarrow \: 2x = 180 - 88 \\ \sf \hookrightarrow \: 2x = 92 \\ \sf \hookrightarrow \: x = \frac{92}{2} \\ \sf \hookrightarrow \: x = 46[/tex]

Answer:

46 degrees

Step-by-step explanation:

Sum of interior angles of a triangle is 180,

x + x + 88 = 180

2x + 88 = 180

2x = 180 - 88

2x = 92

x = 92 / 2

x = 46 degrees

Answer:

It is a function

Step-by-step explanation:

A linear function

[tex]x = y - 3[/tex]

and

[tex]x = y - 4[/tex]

The required interval is (-∞, 0) for which the given function h(x) = x² - 1, has the negative rate of change.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
Given expression,
h(x) = x² - 1

Since the above expression is of parabola, which has a decreasing curve from (-∞, o), simultaneously the function shows the negative rate of change until the function is decreasing, So the required interval for which the function shows the negative rate of change is (-∞, 0).

Thus, The required interval is (-∞, 0) for which the given function h(x) = x² - 1, has the negative rate of change.

Answer:

68

Step-by-step explanation:

25% of a number is 20, where the number is 80 because 25% times 4 is 100% and 20 times 4 is 80.

We can check by doing 60% of 80 to see if it is 48. Instead of 60%, we can do 10% of 80, which is 8. Since we divided by 6, we multiply 8 by 6 which is 48.

Since we know 80 is the number, we have to find 85% of 80. First, let's find 5% of 80, which is 4 since 4 x 20 is 80 and 5% x 20 is 100%. Now, 85 divided by 5 is 17, let's multiply 17 by 4 to get 85% of 80. 17 x 4 is 68 which is 85% of 80.

Answer:

[tex]150.8 < 487[/tex]

Step-by-step explanation:

Given

[tex]C = 487cm[/tex] -- Actual measurement

[tex]M = 150.8[/tex] -- Recorded measurement

Required

Is M < C or M > C?

By comparing both values, we can see that:

[tex]M < C[/tex]

Because, on a number line from right to left; 150.8 comes before 487.

Hence:

[tex]150.8 < 487[/tex]

Answer:

0.0977

Step-by-step explanation:

From the question,

A = πR²...................... Equation 1

Where A = Area of the circular flower garden, R = Radius of the circular flower garden.

Also,

A' = πr²..................... Equation 2

Where A' = Area of the circular pool, r = radius of the circular pool.

If a coin is tossed at random into the garden, the probability that the coin will land in the pool is

Pr = Area of the pool(A')/Area of the garden(A)

Pr = A'/A....................... Equation 3

Substituting equation 1 and 2 into equation 3

Pr = πr²/πR².

Pr = r²/R².................... Equatio 4

Given: R = 16/2 = 8 feet, r = 5/2 = 2.5 feet.

Substitute these values into equation 4

Pr = 2.5²/8²

Pr = 6.25/64

Pr = 0.0977

The height of rock 4 seconds after it was thrown is 168 ft.

Speed is measured as distance moved over time.

Speed = Distance/ Time.

Here, given that,

we have

a rock is thrown off a bridge 40 feet above a river at an initial velocity of 96 feet per second.

The height h, in feet, of the rock

t seconds after it was thrown can be modeled by the function

h(t)=-16t^2 +96t+40.

where

h -----> is the height in feet of the rock

t -----> the time in seconds

For , t=4, we get,

substitute the value of t in the function and find the value of h

h(4)=-16×4^2 +96×4+40.

So, h= 168

Hence, the height of rock 4 seconds after it was thrown is 168 ft.

ANSWER:    X = 5

(x = 5 ),  (x = - 2 )

Step-by-step explanation:

when 10 is subtracted from the square of a number the result is 3 times the number.

Find the positive solution.

Let:   x = number

Let x^2 = square of a number.

x^2 - 10x = 3x transpose

x^2  -  3x - 10 = 0

Apply Factoring: Fractions of  10  are   5  and 2

( - 5)(2)  =   - 10

- 5  + 2  =  - 3

( x - 5 )(x + 2) = 0

x - 5 = 0      x + 2 = 0

x = 5             x   =  - 2

So the positive solution is:

ANSWER:    X = 5
