Step-by-step explanation:

Answer:

option 2

Step-by-step explanation:

QR = 15 ( triangle is a 8- 15- 17 Pythagorean triple )

cosP = [tex]\frac{PR}{PQ}[/tex] = [tex]\frac{8}{17}[/tex] ≠ [tex]\frac{8}{15}[/tex]

tanQ = [tex]\frac{PR}{QR}[/tex] = [tex]\frac{8}{15}[/tex] ≠ [tex]\frac{15}{8}[/tex]

sinP = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{15}{17}[/tex] ≠ [tex]\frac{8}{17}[/tex]

cosQ = [tex]\frac{QR}{PQ}[/tex] = [tex]\frac{15}{17}[/tex] ← correct statement

Answer:

its the cos q = 15/17

Step-by-step explanation:

cos q = 15 (adjacent) / 17 (hypothenuse)

Answer:

The percent of interest is 12.3% per year

Step-by-step explanation:

According to the question Elwood invested 5000 $ in market account

The market account gives the compound interest annually

let p be the interest per year then

At the end of 1st year

amount =(1+0.p) x 5000  = 1.p x 5000

similarly at the end of 2nd year

amount =(1+0.p) x(1+0.p)x 5000  = [tex](1.p)^{2}[/tex] x 5000

similarly at the end of 3rd year

amount = 7100 $ = [tex](1.p)^3[/tex] x 5000

⇒ [tex]\frac{71}{50}[/tex] = [tex](1.p)^3[/tex]  

1.392 =  [tex](1.p)^3[/tex]

on further solving we get

1.p = [tex](1.42)^{1/3}[/tex] = 1.123

thus 1.p = 1 + 0.p = 1.123

thus p = 0.123

thus the percent of interest is 12.3% per year

Answer:

drop down 1 a slower rate per year

drop down 2 670

Step-by-step explanation:

as in three years you get $7100

you take that and subtract it by your starting amount (5000)

7100-5000= 2100

then divide 2100 by the number of years (3)

to get your annual rate of 700$

then you take the 8 year total and subtract it from your 3 year total

10350-7100= 3250

Then divide that by 5 because that how many years it has been

to get the annual rate of 650

making the 5 year rate slower.

The to find the average rate over all 8 year you take 10350 and subtract it from your starting number 5000

10350-5000= 5350

then take 5350 and divide it by the number of years (8)

you then get you average rate of 668.75

668.75=670

Hope this helps!

Answer:

0,13

Step-by-step explanation:

the answer of the question is 14/25

Step-by-step explanation:

Equating two statements is called proportion. By property of the proportion, the cross product of the mean is equal to cross product of the extreme. Also we can denote as ratio of extreme and mean.

A×B=B×C

Answer:

The answer would be A

Step-by-step explanation:

The Y axis represents the distance Liana traveled from 0 (campsite). the X axis represents the amount of time.

Liana travels away from the campsite for 30 minutes (slope), and then she stops completely for 10 minutes (no Y axis moments). She then returns back to camp faster (minutes)

Every other answer is incorrect as they maintain a single block from the graph, and each block is counted as 5 minutes. The only answer that has that 10 minute wait is answer A

The correct graph of this situation is showing in Graph 2.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes,

And, Finally she hikes back to her campsite at a faster pace, reaching it in 20 minutes.

Now,

Let time is showing on x - axis.

And, Distance from campsite in on y - axis.

Hence, In graph 2;

Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes, And, Finally she hikes back to her campsite at a faster pace, reaching it in 20 minutes.

Answer:

Please check the explanation.

Step-by-step explanation:

Show that 4x - x² - 7 is always negative.

Given

4x - x² - 7

4x - x² - 7 is always negative because:

Hence, 4x - x² - 7 is always negative

For example,

let suppose we enter x = 1

[tex]4(1)-1^{2} -7\\=4-1-7\\=4-8\\=-4[/tex]

let suppose we enter x = -1

[tex]4(-1)-(-1)^{2} - 7\\= -4 - 1 - 7\\= -12[/tex]

Answer:

Stephanie sprinted 550 yards.

Step-by-step explanation:

Given that,

Stephanie ran three sprints during practice.

Her first sprint was 175 yards, her second sprint was 150 yards, and her third sprint was 225 yards.

We need to find the total distance that Stephanie sprinted. It is simply equal to the sum of all above sprints.

Distance = 175 yards + 150 yards + 225 yards

= 550 yards

Hence, Stephanie sprinted 550 yards.

Answer:

the  percentage of the students in the band that play a percussion instrument is 14.6%

Step-by-step explanation:

The computation of the percentage of the students in the band that play a percussion instrument is as followS;

= number of students played percussion instrument ÷ total number of students

= 6 students ÷ 41 students

= 14.6%

Hence, the  percentage of the students in the band that play a percussion instrument is 14.6%

Answer:

[tex]\displaystyle \frac{d}{dx} \Big [ \frac{3}{x^2} \Big ]=-\frac{6}{x^3}[/tex]

Step-by-step explanation:

We can use either the Power Rule or the Quotient Rule to find the derivative of 3/x².

Rewrite [tex]\displaystyle \frac{3}{x^2}[/tex] as [tex]\displaystyle 3\cdot \frac{1}{x^2}[/tex] which is equivalent to [tex]3\cdot x^-^2[/tex].

Now we can apply the power rule to 3x⁻². Subtract 1 from the exponent and multiply the coefficient by -2.

This can be rewritten as [tex]\displaystyle -\frac{6}{x^3}[/tex].

Substituting 3 for f(x) and x² for g(x), we get:

Simplify.

Using exponent rules, we can rewrite this as:

This can be rewritten as [tex]\displaystyle -\frac{6}{x^3}[/tex], which is the same as what we got using the product rule.

Answer:

[tex]\displaystyle \frac{d}{d x}\left[\frac{3}{x^2}\right] = -\frac{6}{x^{3}}[/tex].

Step-by-step explanation:

Let [tex]f(x)[/tex] and [tex]g(x)[/tex] denote two functions of [tex]x[/tex]. Assume that [tex]g(x) \ne 0[/tex]. The quotient rule states that:

[tex]\displaystyle \frac{d}{d x}\left[\frac{f(x)}{g(x)}\right] = \frac{{f}^\prime(x) \cdot g(x) - f(x) \cdot g^{\prime}(x)}{{(g(x))}^2}[/tex].

In this question:

Find [tex]{f}^{\prime}(x)[/tex] and [tex]{g}^{\prime}(x)[/tex].

Notice that the value of [tex]f(x)[/tex] is constantly [tex]3[/tex] regardless of the value of [tex]x[/tex]. By the constant rule, [tex]{f}^{\prime}(x) = 0[/tex].

For [tex]{g}^{\prime}(x)[/tex], consider the power rule:

if [tex]m[/tex] represents a rational number (such as [tex]2[/tex],) then by the power rule, [tex]\displaystyle \frac{d}{d x}\left[{x}^{m}\right] = m\, {x}^{m-1}[/tex].

Apply this rule to find [tex]{g}^{\prime}(x)[/tex].

[tex]\begin{aligned}{g}^{\prime}(x) &= \frac{d}{d x} \left[x^{2}\right] \\ &= 2\, x^{2 - 1} \\ &= 2\, x\end{aligned}[/tex].

Substitute [tex]f(x) = 3[/tex], [tex]{f}^{\prime}(x) = 0[/tex], [tex]g(x) = x^{2}[/tex], and [tex]{g}^{\prime}(x) = 2\, x[/tex] into the quotient rule expression to find [tex]\displaystyle \frac{d}{d x}\left[\frac{3}{{x}^{2}}\right][/tex]:

[tex]\begin{aligned}&\; \frac{d}{d x}\left[\frac{3}{{x}^{2}}\right] \quad \genfrac{}{}{0em}{}{\leftarrow f(x) = 3}{\leftarrow g(x) = {x}^{2}} \\ =&\; \frac{d}{d x}\left[\frac{f(x)}{g(x)}\right]\\ =&\; \frac{{f}^\prime(x) \cdot g(x) - f(x) \cdot g^{\prime}(x)}{{(g(x))}^2} \\ =& \; \frac{0 \, x^2 - 3\, (2\, x)}{\left({x}^{2}\right)} \\ =&\; -\frac{6}{x^{3}}\end{aligned}[/tex].

Therefore, [tex]\displaystyle \frac{d}{d x}\left[\frac{3}{{x}^{2}}\right] = -\frac{6}{x^{3}}[/tex].

Answer:

Solving the expression: [tex]\frac{3}{4}g=-12[/tex] we get: [tex]\mathbf{g=-16}[/tex]

Step-by-step explanation:

We need to solve the expression: [tex]\frac{3}{4}g=-12[/tex] and find the value of g

Solving:

[tex]\frac{3}{4}g=-12[/tex]

Multiply both sides of the equation by [tex]\frac{4}{3}[/tex] because we need to find value of g.

[tex]\frac{3}{4}g\times \frac{4}{3} =-12\times \frac{4}{3}\\g=-4\times 4\\g=-16[/tex]

So, we get g = -16

Solving the expression: [tex]\frac{3}{4}g=-12[/tex] we get: [tex]\mathbf{g=-16}[/tex]

Answer:

10 meters

Step-by-step explanation:

Use the Pythagorean Theorem for this one:

[tex]a^{2} + b^{2} = c^{2}[/tex]

If a = 6, b = 8, then:

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]6^{2} + 8^{2} = c^{2}[/tex]

[tex]\sqrt{6^{2} + 8^{2}} = c[/tex]

[tex]\sqrt{36 + 64} = c[/tex]

[tex]\sqrt{100} = c[/tex]

[tex]10 = c[/tex]

[tex]c = 10[/tex]

According to the Pythagorean theorem, if the flagpole is 6 meters high and the hook is 8 meters from its base, the rope is 10 meters long.
